This coal-gasification process produces [H.sub.2]- and CO-rich syngas in separate streamsA coal-gasification reactor that resembles a metals smelter and operates in two cycles (oxidation and reduction), alternately producing hydrogen and syngas, is being deve...
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 ...
with the pressure drop across the gap opening and the opening ratio. Fang et al. (2003) developed a twin fluidized bed solid circulation system for coal gasification to produce middle heating value gas and proposed design parameters for the commercial gasifier design. Miccio et al. (2012) ...

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,... - 《...
(ex.: blast furnaces can produce about 15,000 tonnes of iron per day9). Cheap and abundant reactants such as coal and air have been at the heart of pyrometallurgical processes for centuries. They are used to calcine, roast, smelt, convert and refine metals. The strong affinity of carbon...
Underground coal gasification (UCG) as an efficient method for the conversion of the world's coal resources into energy, liquid fuels, and chemicals has attracted lots of attention in recent years. This paper is concerned with a feasibility study of the UCG process for Alberta reservoirs using ...
In the field of thermal conversion, the van Krevelen diagram has been widely used to intuitively indicate differences in H/C and O/C ratios among feedstocks and products in processes such as torrefaction20, hydrothermal carbonization21, pyrolysis22, and gasification23. This application provides a un...
Because an old horizontal reactor doesn't make good use of the energy of plasma,some experiments on plasma coal gasification are carried out to get some basic working conditions in a new vertical reactor designed recently. The effects of the temperature and the concentration of oxygen on plasma ...
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...
