Abstract

Abstract. The paper reports on kinetic analysis of various biomass / coal blends at different mixing ratios for determination of kinetic parameters (activation energy (Ea) and pre-exponential factor (A)) of best mixture for co-gasification purpose. Biomass materials (chicken litter, corn stover, pine wood, eucalyptus wood and cow dung), and coal (sub-bituminous) were used in the study. Thermogravimetric analysis (TGA) was conducted to investigate the kinetic parameters and thermal stability for various biomass/coal blends. A mixture of 90% corn stover and 10% coal resulted in the highest thermal stability compared to others with the activation energy value and pre-exponential factor of 3.7728 x 10-3 J/mol and 1.4979 x 10-4 min-1 respectively. The thermal analyses obtained for the different blends will be presented and discussed in detail in the paper. Keywords: Biomass, coal, TGA, Activation energy and pre-exponential factor
