A literature review was conducted on In Situ Coal Gasification with particular attention to environmental effects, benefits and process controls of this emerging technology. In Situ coal gasification also known as Underground Coal Gasification (UCG), appears to be both technically and economically ...
Modeling and simulation of coal gasification on an entrained flow coal gasifier In this paper, the recent researches and developments on coal gasification modeling and simulation are described. Numerical models for the three chemical p... HKR Watanabe - 《Advanced Powder Technology the Internation Jour...
Therefore, in the case of early water intrusion, the higher the moisture content of the coal is, the smaller the gas desorption amount, and the slower the desorption rate. This situation is different from that when using hydraulic technology in a coal seam. In the field, the coal seam ...
Existing and projected shortages of natural gas in the United States have stimulated extensive research to develop the technology for commercial production of synthetic high-Btu gases of pipeline quality. In this general effort, coal gasification has been given particular emphasis because of the ...
The scrubbing–cooling chamber plays an important role in the coal entrained-flow gasification technology containing water quench process as a washing and cooling device for high temperature crude coal gas. A composite bubble column is employed in an opposed multi-burner (OMB) gasifier named scrubbing...
Two exposures were carried out in the gasifier of the Westinghouse Process Development Unit to evaluate the performance of a wide variety of candidate construction materials for hostile high temperature, high pressure coal gasification environments. The test materials included highly alloyed iron-, cobalt...
A theoretical solution of the channeling effect is presented. The details of the channeling production are investigated in detail and an approximate method... K Vafai - 《Journal of Energy Resources Technology》 被引量: 27发表: 1986年 Catalytic Gasification of Coal using Eutectic Salt Mixtures The...
New Trends in Coal Conversion: Combustion, Gasification, Emissions, and Cokingcovers the latest advancements in coal utilization, including coal conversion processes and mitigation of environmental impacts, providing an up-to-date source of information for a cleaner and more environmentally friendly use ...
