Gasification characteristics and kinetics of briquette using humic acid binder
摘要
Abstract
Briquette was made from a low active pulverized Fujian anthracite with humic acid as binder. The gasification reaction kinetics and characteristics of briquette were compared with those of Fujian anthracite. The steam gasification rate was determined at the temperature of 900 ~ 1 150℃ and atmospheric pressure by using the isothermal thermogravimetry. The kinetic parameters of gasification were calculated based on the shrinking-core model (SCM). The data show that the activation energy of briquette is 102.0 kJ/mol, lower than that of Fujian anthracite( 122. 5 kJ/mol). The carboxyreactivity of briquette is 80. 0% at 950℃ , while it is only 33. 0% for Fujian anthracite granule. The results exhibit that the briquette has a higher gasification reactivity than Fujian anthracite lump, and could be a substitute of high quality lump coal for the industrial fixed bed gasification.关键词
