CO-GASIFICATION COAL AND BIOMAS: RESEARCH THE EFFECT OF TEMPERATURE AND MIX RATIO ON BIOMASS CONVERSION ON TGA

Abstract

Cashew nut shell (CNS) is a waste in cashew nut processing but can be considered
as a by-product when used as fuel for pyrolysis, gasification or direct combustion for
energy production at medium and small scale. Gasification is an advanced and
potential technology to produce artificial gas with required properties of heat value
and certain cleanliness for application to gas turbine cycles, replacing liquefied
petroleum gas for high-quality ceramic kilns is still a question mark. Therefore, the
study of optimizing coal gasification and CNS to produce gas with high heat value is a
matter of concern to many researchers at present. In this article, method and results of
research on coal-biomass gasification process are presented under different
temperature conditions and other mixing ratios on TGA equipment. Experimental
results at different temperatures (550 - 700
o
C) and at the mixing ratio of coal - CNS (20
- 80% of biomass) indicate that the time and rate of fuel conversion are different,
respectively. Especially in the different coal-biomass mixing ratio, we can clearly see
the mutual influence of the mixed sample on the sample conversion rate and speed.
