Abstract

In the present study, char samples of two biomasses and their blends with high ash Indian coal were prepared at 900°C and then gasified in the temperature range of 850°C to 1000°C in CO2 atmosphere using thermogravimetric analyzer (TGA). It is observed that the char gasification reactivity of coal-biomass blend is lesser in comparison with the gasification reactivity of pure biomass. The effect of gasification temperature on reactivity as well as comparison between gasification of two pure biomasses and their blends with coal have been studied. The activation energy of biomass and their blends has also been discussed in this paper. The gasification reactivity and kinetic data developed from thermogravimetric analysis study may be useful for modelling and designing of suitable gasifier as per the available feedstocks.
