Abstract:

 Biomass tar contained in biomass gas is still an obstacle in biomass thermo-chemical conversion technology. The basic process of tar removal by solvents was given. ASPEN PLUS, one of the most famous softwares of chemical engineering, was used to stimulate the process. The measures to increase the rate of tar removal were obtained by analyzing the influence of technological factors such as flux and temperature, which were suitable for practical productions.

Key words: biomass gas； tar removal； ASPEN PLUS
