The U.S. Congress has been struggling to create a comprehensive energy program. A key component of the present attempt, recommended by President Carter, is a synthetic fuel program. In July of 1979, the President asked for an $88 billion “crash program” to encourage development of synthetic fuels. To date, a three month struggle to reach a consensus between House and Senate conferees has brought only limited results. Compromise is emerging in the form of a proposal for a “synthetic fuels corporation.” The body would have the authority to disperse $20 billion in the form of federal loan guarantees and purchase agreements with more money to become available later.

Coal‐tar pitch, either in its simple form or as part of more complicated formulations, is being increasingly used in modern times for the heavy‐duty protection of steelwork, concrete, non‐ferrous metals, etc. wherever the utmost in resistance to corrosion is required. Wailes Dove Bitumastic Ltd., of Hebburn, Co. Durham, have been specialists in coal‐tar pitch compositions for over 100 years and are in the vanguard of research to extend its possibilities to keep pace with modern needs for corrosion prevention. This report traces the development of coal‐tar pitch from its use as a simple, single material to its use in the most modern and advanced type of coatings.

The purpose of the study is to evaluate the impact of China's current coal‐to‐liquids (CTL) activities on its coal and oil markets from 2005 to 2025.

A partial equilibrium multi‐equation model of China's oil and coal markets is developed based on data obtained from the existing literature. The impact of CTL technologies on China's oil and coal markets is evaluated using computer simulations by solving the model under scenarios with and without CTL production.

The simulation results show that on average, the planned CTL activities will decrease crude oil prices by 5.73 percent and China's oil imports by 6.09 percent and increase China's domestic oil supply by 9.26 percent over the 20 year period. Also, China's demand for oil will increase by 0.35 percent on average, suggesting that CTL production will slightly stimulate China's demand for oil because of the drop in oil prices. China's demand for coal will also increase by 1.02 percent because of the additional demand for coal created by CTL production. Surprisingly, both coal prices and China's coal supply will decline by 0.51 percent while the demand for coal and coal supply of the rest of the world will be reduced by 1.63 percent and 0.28 percent, respectively.

The paper is the first study on the implication of CTL conversion from an economist's point of view. It applies an economic model to quantify the impacts of such technology on overall energy prices and supplies.

The purpose of this paper is to explore key factors or criteria of sustainable supply chain management (SSCM) influencing Indonesian coal companies, using “adoption, implementation, and performance” (A-I-P) of SSCM, thru three means: first, to investigate which criteria have higher weight to achieve SSCM in Indonesia; second, to see whether there are any differences between the Indonesia case and existing literature of SSCM; third, to highlight any causal relationships between the Indonesia case and the SSCM theory.

DEMATEL-based analytic network process (DANP) questionnaire survey with a theoretical SSCM model is applied to conduct an empirical test for the coal production and supply chain companies in Indonesia.

The “performance” dimension out of the A-I-P of the SSCM is the most important one, while the “adoption” dimension is the least. Out of the 12 criteria under the three dimensions, the “operational, economic, environmental, and social” factors under the category of the performance dimension and the “ISO 14001 certification” criteria belonging to the dimension of “implementation” are the top five key factors in the SSCM.

There are some limitations in this study. First and foremost is the relatively small sample size with a limited geographic area, although they are unavoidable owing to one country case study.

The test results are helpful to draw guidance for sustainable supply chain managers in implementing efficient SSCM in the wave of tough competition and changing marketplace.

This study contributes first to developing a theoretical framework for SSCM under the A-I-P model and second, to applying DANP to an empirical case of SSCM of the coal industry in Indonesia. As a result, the authors draw helpful guidelines and policy implications for SSCM of the coal industry, referring to the A-I-P dimension as drivers and enablers for the SSCM performances of the industry.

Energy is a driving force of economic development in the modern world, while as a commodity group it holds the greatest share of the world seaborne trade. Oil, natural gas and coal are the three most important sources of energy for the European Union which, as a bloc, represents 17% of the total energy consumption. The aim of the present paper is to explore the economics and trade issues of these three major energy commodities and investigate the role of the maritime transport in the energy trade within the context of the EU-25. A number of factors are considered in order to discuss contemporary opportunities and challenges that arise in this context for the shipping business. The examination reveals the critical dependence of EU-25 energy supply on seaborne trade and the considerable reliance of the maritime transport on such commodities for the generation of shipping business within the realms of the EU-25. Among the parameters regarded as conducive to the demand of shipping services in the context of the EU energy trade are the energy demand factor, the import dependency factor, the cost effective production element, and seaborne trade related parameters while consideration is also given to environmental issues.

This paper aims to take the four resin as adsorbent and coal ash alkaline solution as the material and use the single factor experimental method to study absorption influence factors for each resin to absorb lithium. At the same time, the authors got the special properties of some kinds of resin and compared the test results of each resin at the optimum factors.

Because many factors affect the test, this study uses the method of comparison and control variables. This method study on the influencing factors of ion exchange resin adsorption Li⁺.

In these adsorption experiments, the basic resin adsorption effect is more obvious. The optimum adsorption conditions are as follows: resin quality is 0.1 g, the volume of fly ash solution is 100 ml, magnetic stirrer speed is 140 r/min and the adsorption time is 60 min. Under these conditions, the adsorption rate of Li⁺ could reach 25.17 per cent aluminum.

Li extracted from coal ash can not only relieve the lithium resources in short supply but can also provide a new mode to the field of coal resources in recycling economy and transition economy. At the same time, the extraction of Li resources will provide an important reserve of raw materials for the future of nuclear power plant.

This study aims to focus on the submicron particles (with diameter of 0.2-1.0 μm) of the ambient air from a coal-fired power plant. A systematic examination of their morphology, particle size and chemical element will be analyzed, so as to provide more scientific information and theoretical basis for the formation and control method of inhalable particles, as well as data support for environmental impact and ecological effects assessments.

In this paper, the morphology, size distribution and elemental characteristics of submicron particles from ambient air of a coal-fired power plant are studied by single particle analysis.

The results show that atmospheric particles in coal-fired power plant are mainly spherical particles, and most of them are soot aggregates adhered or coated with other particles with few rectangle particles. The particles collected in the afternoon and evening are mainly of spherical particles, and small-sized particles collected in the morning are mainly spherical ones, while the overall concentration is larger than that of the spherical particles in the size range above 0.5 μm. The results indicated that the larger-sized spherical particles have a lower concentration.

Coal-fired power plants are still the main supply of electricity in China, but the inhalable particles, especially sub-micron particles (0.1-1.0 μm) cannot be effectively captured by the dust removal device from the coal-fired power plant. Thus, a large amount of inhalable particles is emitted into the atmosphere, becoming the major air pollutants in China.

Animal liquid manure contains large amounts of phosphorus (P), which is susceptible to runoff losses when manure is surface-applied on farms as a soil amendment. Even very small quantities of P can have a large impact on waterways and lead to eutrophication. Previous studies have shown that flue gas desulfurization (FGD) gypsum, a coal combustion by-product, can reduce P losses from runoff in soils. Therefore, the authors hypothesize that FGD gypsum could reduce nutrients in liquid manure prior to field applications. The purpose of this paper is to evaluate the effect of FGD gypsum to reduce P and suspended solids (SS) concentrations in liquid manure, also determining its proper rate(s) and minimum time of reaction.

The experimental design was completely randomized with three replicates. Each plot was constituted by a polyvinyl chloride (PVC) column (1 m height and 0.15 m diameter). Dairy liquid manure and FGD gypsum rates (0, 0.62, 1.25 and 2.5 mgl⁻¹) were added to the PVC columns and manually shaken for two minutes. Sampling was performed at 0.35, 0.65 and 0.95 m depths after 0 (immediately after shaking), 4, 8, 16 and 24 hours. Amount of phosphorus was determined by a colorimetric method and solids concentration by mass difference.

FGD gypsum reduced P concentrations in the liquid manure after four hours of reaction. The most effective rate was 0.62 mgl⁻¹at a 0.35 m depth. FGD gypsum increased SS concentrations in depth in all treatments.

There are growing concerns regarding the fate of nutrients, especially phosphorus, from land application of animal waste. The results indicated that treating liquid manure in the settling tanks with FGD gypsum before field application can be particularly useful on farms where surface-manure is applied, reducing potential losses of P following manure applications, and consequently the eutrophication risk to waterways.

This article is based on the REACCESS research project, sponsored by the European Commission, with the objectives of evaluating the technical, economic, and environmental aspects of present and future energy corridors between the European countries (EU27) and their main energy suppliers. GCC countries have an important role to play given their role in EU energy supply and in greenhouse gas emissions. The paper aims to discuss these issues.

A single energy model was built by hard‐linking the TIMES integrated assessment model (TIAM‐World), the Pan European TIMES model (PET), and the RECOR model (REaccess CORridors), including more than 1,000 possible energy corridors supplying the European countries. Another major methodology advance was to create a hybrid objective function, combining the usual cost objective and a metric representing the supply risk incurred by EU27. The risk component was constructed via a novel approach that aggregates the elemental risk parameters of each corridor using a Min‐Max function. Four contrasted scenarios were assessed, based on security and climate objectives.

Among the many results, it appears that a large reduction of the supply risk may be achieved at a very modest increase of the total energy system cost for EU27. Cross‐effects of climate mitigation and security objectives are also observed. Due to the diversification requirement, the contribution of GCC countries to EU energy imports increases under risk scenario. Sensitivity analyses show that the European energy system seems unable to reduce the market shares of fossil fuels import from MENA countries, including GCC countries, much below the reference case, proving the strong dependency of EU27 energy system from these countries. However, total fossil fuels imports, as well as total energy consumed, are decreased under the risk adverse scenarios.

Methodological developments, as described above, result in an advanced tool to assess how to increase the “energy system security”, by reducing the concentration of supply countries, diversifying import sources but also reducing the energy dependence at the end‐use side.

To be competitive, capitalism must lower the cost of production by lower wage costs, lower inflation, lower interest rates, and lower taxes. The welfare state has become the greatest hindrance because it supports costly wage rates even in a recession with high unemployment. The consequences of a weak welfare state, however, are rising unemployment, poverty and crime. But an internationally‐oriented economy does not need to depend on local demand, much of which is created by full employment. One solution is for the unemployed to become self‐employed. Capitalism, over the years, has achieved an unlimited capacity to produce, improve and diversify output at a declining cost per unit of output, but paradoxically has created an increasing problem in marketing its ever‐expanding output. Attempts to explain this.
