A method of estimating the reaction process of coal gasification from the composition of gas produced

Abstract

The method to derive reaction formula, CH_mO_n+αO_2+βH_2O→γCO+δH_2+εCO_2+ζH_2O+ηCH_4, from the composition of gas produced has already reported. In order to elucidate the reaction process of gasification, we tried to deform the stoichiometric formula theoretically, CH_mO_n+0.5(1-n)O_2→CO+0.5mH_2, into the actual formula by taking account of the effect of subsequent reactions caused by excess or lack of oxygen, water gas reaction, shift reaction and CH_4 formation. We have presumed the contribution of shift reaction to the performance of HYCOL process.
