EXPERIMENTAL STUDY ON THE CHARACTERISTICS OF BIOMASS GASIFICATION IN A FIXED-BED GASIFIER
IntroductionGasification technology is used to produce synthetic gas from coal, petrolcum substances, and other fossil fuels. However, in recent years, gasification technology is increasingly being used for treating biomass and polymer wastes, making it an environmentally friendly technology 1. The major components of dried woody biomass include cellulose (50 wt%), hemi-cellulose (20 wt%), and lignin (30 wt%), each interconnected in crystallized or uncrystallized form. When gasifying biomass, the structure collapses due to the ablative reaction occurring during the initial gasification stage at temperatures over 300 ℃, and the large molecular chains are broken, turning the substance into a liquid. At a higher reaction temperature, the ablated liquid undergoes thermal decomposition, and is finally converted into gas, or a low molecular weight mixtureThe synthetic gas produced by the gasification of biomass is made up of H2, CO, CH4, N2, CO2, O2, and tar. When gasifying biomass, tar that is formed together with the synthetic gas is difficult to remove with a physical dust removal method. Tar is a hydrocarbon compound that remains liquid at room temperatures. It can be condensed, and is a mixture of diverse ring structure substances.
