AbstractAbstract
[en] Underground Coal Gasification (UCG) is the conversion of coal in the seam into a combustible gas. UCG is conceptually very simple but controlling the reaction and producing a consistent gas quality under a variety of geological and coal conditions is difficult to achieve. The basic concept has two boreholes, one for the injection of oxidants and the other for the removal of the product gas. (authors)

AbstractAbstract
[en] A phenol-formaldehyde polymer carbon with a very low ash content (<0.01%) and a widely developed porosity has been used to analyze the effect that its surface chemistry has on calcium dispersion and, therefore, on its catalytic activity. Two calcium loading levels have been studied; one with a percentage of calcium near to the maximum ion-exchange capacity of the carbon and the other with a higher calcium loading. Different techniques (TG-DTA, TPD-MS, XPS, EXAFS, XRD) have been used to analyze the surface chemistry of the carbon and properties of the calcium as initial distribution, dispersion and catalytic activity. The results show that the surface chemistry of the carbon controls the distribution and growing of calcium particles during the preparation step and, therefore, determines its dispersion, the calcium-carbon contact and its catalytic activity. This study shows that the calcium-carbon contact is directly related to the calcium ion-exchanged with the carboxylic groups of the carbon. (author)

AbstractAbstract
[en] The US electric power production market is experiencing significant changes sparking interest in the current and future alternatives for power production. Coal gasification technology is being marketed to satisfy the needs of the volatile power production industry. Coal gasification is a promising power production process in which solid coal is burned to produce a synthesis gas (syn gas). The syn gas may be used to fuel combustion integrated into a facility producing electric power. Advantages of this technology include efficient power production, low flue gas emissions, flexible fuel utilization, broad capability for facility integration, useful process byproducts, and decreased waste disposal. The primary disadvantages are relatively high capital costs and lack of proven long-term operating experience. Developers of coal gasification intend to improve on these disadvantages and lop a strong position in the power generation market. This paper is a marketing analysis of the partial oxidation coal gasification processes emerging in the US in response to the market factors of the power production industry. A brief history of these processes is presented, including the results of recent projects exploring the feasibility of integrated gasification combined cycle (IGCC) as a power production alternative. The current power generation market factors are discussed, and the status of current projects is presented including projected performance

AbstractAbstract
[en] Underground coal gasification (UCG) is in its nascent stage of development. Most of the projects are in the nature of pilot projects. UCG technology requires acceptance in general commercial framework as it matures with the progress of time. Policy and regulatory framework, therefore, is considered here only in the expectation that UCG technology may finally be rolled out sooner than later. India is actively pursuing consultations with major countries which have recorded successes in implementing UCG technology in varying measures. In this background, the discussion on policy and regulatory framework is essentially an effort to capture the broad outline of the understanding of the UCG process in a regulatory construct as compared with other regulatory regimes of similar nature.

AbstractAbstract
[en] In the existing in Kazakhstan fuel-energy situation the important significance has got the non-traditional geo-technological ways of minerals extraction. These methods stipulating transformation of coals and shale oils into mobile state within the productive thickness. These methods in the high level meet to the principles of recycling technologies. Key place among geo-technological methods of development, reprocessing solid combustible minerals is the underground gasification of coals (UGC). The technology is based on the coal transformation into combustible gas in the depth at an deposit. In the Kazakhstan there are lignite deposits most auspicious for organization of UGC methods. The deposits are as follows: Low-Ili and Lenger (South Kazakhstan), Chernigov (North Kazakhstan). At the same time these deposits are unfavourable for traditional development technologies

AbstractAbstract
[en] During recent approach the basic emphasis is on electricity generation from coal. Electricity generated from hydroelectric power plants is not enough to meet today's demands, so it's the necessity of day to seek alternate sources. Coal is the most abundant and versatile fossil fuel. Pakistan's total coal reserves are estimated to be around 184.5 billion tones, which also included recently discovered deposits of low sulphur coal at Thar. Out of these large reserves Pakistan utilizes only 40 million tones per year. The existing coal reserves in the country could meet the requirements of 6 power plants of 1000 MW for next 30 50 years, but currently coal makes merely 1% of electricity generation. In this coherence, coal-burning power plant with zero toxic gases/solids emissions is proposed. The traditional coal power plant can be installed for electricity generation and with use of different environmentally sound technologies, so that emission of toxic gases or solids is captured at the source and finally used for other useful purposes.

AbstractAbstract
[en] This presentation focuses on the use of low rank coals to form synfuels. A worldwide abundance of low rank coals exists. Large deposits in the United States are located in Texas and North Dakota. Low rank coal deposits are also found in Europe, India and Australia. Because of the high moisture content of lignite ranging from 30% to 60% or higher, it is usually utilized in mine mouth applications. Lignite is generally very reactive and contains varying amounts of ash and sulfur. Typical uses for lignite are listed. A commercial application using lignite as feedstock to a synfuels plant, Dakota Gasification Company's Great Plains Gasification Plant, is discussed
