OVERVIEW OF THE STUDY AFFECTING EXPERIMENTAL CONDITIONS FOR GAS PRODUCTS AND TAR TRANSFORMATION IN COMBINATION OF COAL AND COMBUSTION

Abstract

Biomass (biomass) is a renewable fuel that has attracted the attention of
many scholars in recent years because it is a carbon-free (or carbon-neutral) fuel
and will help create new economic opportunities, especially in rural areas.
However, because biomass has special properties such as high volatile matter,
low calorific value, high moisture content,... compared to fossil fuels (coal).
Therefore, the biomass gasification combined with coal is currently interested by
many scientists to create gas products that meet the requirements of
composition and properties. The following article briefly describes a number of
current studies in the world on gasification of coal and biomass mixes, the
influence of experimental conditions on gas product composition and tar
conversion. From that, determine the next research direction on gasification:
choose biomass type and coal type, catalyst, optimize the gasification
temperature, mixing rate and other gasification conditions.
