A process for the gasification of coal is disclosed, the process being characterized by the removal of flyslag deposits in the quench zone of the process by temporary reduction or stoppage of the flow of the quench gas to melt the deposits, and by diversion of a portion or all of the ...
And improved coal gasification process could also be used to improvebiofuel processing technologies. 的确是!并且改进的煤气化处理技术也可以用到生物燃料的处理中。 www.cfeie.com 2. A description is given of the effect of the coal quality used in the Ende pulverized coal gasification process on gas...
The present study aims to explore the physico-chemical structure evolution characteristic during Yangchangwan bituminous coal (YCW) gasification in the pre
The efficiency and economics of the Synthane Gasification process are evaluated and discussed in this paper. The efficiency of the Synthane process was determined using the "availability analysis" approach to process evaluation and is given here as an example of the use of that approach. Computer...
OF THE DISCLOSURE Continuous process for the gasification of par- ticulate coal with steam wherein SO2 is present, preferably through introduction into the steam, thereby enabling the steam to react with the coal at considerably lower than conventional temperatures such as temperatures ranging up- wa...
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 ...
Process Chemistry of Coal Utilization: Reaction Mechanisms for Coal Decomposition and Volatiles Conversionrelates major advances in coal science on how to interpret performance data from lab, pilot and commercial scales. The book presents a very broad range of quantitative methods, from statistical regres...
It also improves on the carbon burnout, ease of ignition and has been used to predict the number of hydrocarbons that can be given out during the gasification process (Hattingh et al. 2011). (2) Organic composition (coal macerals) The organic structure of coal is made up of three maceral...
On this basis, authors have decided to devote more attention to this process. The further research regards coal pyrolysis in various operating reactor conditions. With regard to the model description of gasification presented in Section 3, coal pyrolysis simulation considers the Coal gasification ...
Carbon and catalyst containing chars obtained from a catalytic coal gasification or combustion operation may be separated into two layers of fractions by contacting them with an inert gas so as to flu
