In an underground coal gasification (UCG) process, ( ) coal-seams are reacted with insufficient oxygen to create syngas underground. A. above-ground B. canceling C. untapped D. UCG 如何将EXCEL生成题库手机刷题 如何制作自己的在线小题库 > 手机使用 分享 反馈 收藏 举报 ...
The coal gasification process of a slurry feed type, entrained-flow coal gasifier was numerically predicted in this paper. By dividing the complicated coal gasification process into several simplified stages such as slurry evaporation, coal devolatilization and two-phase reactions coupled with turbulent ...
2 to test the linked vertical well process in a wet, homogeneous coal seam. We plan to carry out... D. Olness,S. Madsen - Monograph on Alternate Fuel Resources; (United States) 被引量: 0发表: 1977年 Instrumentation and process control development for in situ coal gasification. Quarterly ...
gasification temperature is the most important influential factor to coal gasification.Velocity of gas is reduced and resident time of gasifying agent is prolonged at elevated pressure.On the other hand,there is better fluidization in the reactor at elevated pressure.So the efficiency of coal ...
Gasification Reaction of Coal Char with CO_2 Under the Catalytic Action of Alkali Metals The kinetics of gasification reaction of coal char,with CO_2 serving as the gasifying agent,has been studied in a fixed bed test rig and the effect of alka... KL Pang,WG Xiang,C Liang,... - 《...
Then, the structure of coal, and especially the carbon–hydrogen ratio, will undergo significant changes, converting solid coal into liquid oil. The technological process is defined as direct coal liquefaction [4,5]. As an important by-product of the direct coal liquefaction system, the yield ...
Because of significant concern in the gasification process worldwide, it is necessary to anticipate the energy requirement for biomass drying over the remaining moisture content. The energy required for the drying process is supplied substantially by heat produced within the process (exhaust heat) from...
An advanced process has been developed for the separation of H 2 S from coal gasification product streams through an electrochemical membrane. This technol... SR Alexander,J Winnick - 《Journal of Applied Electrochemistry》 被引量: 30发表: 1994年 PALLADIUM/COPPER ALLOY COMPOSITE MEMBRANES FOR HIGH...
The efficient combustion of synthesis gas or ‘syngas’ in gas turbines is becoming more relevant due to the development of integrated gasification combined cycle (IGCC) power plants, where the products of coal gasification are burned in gas turbines [1]. Moreover, syngas can be obtained from ...
