Abstract
Biomass gasification is an attractive power generation technology that can generate electricity without any increase of CO2 concentration in the atmosphere. However, many technical problems have still to be overcome. The biggest technical obstacle for the operation of a commercial gasification plant is the elimination of tar in the producer gas. Tar will condense at the ambient temperature and will cause clogging of pipes and engines. Therefore, effective and economical tar removal methods are required. In this paper, the bio-oil, which was obtained from the existing pilot-scale gasification plant, was utilized as an absorbent for removing tar from the syngas. The result showed that the bio-oil absorbent was effective for tar removal and 73.3% of the gravimetric tar was removed by the bio-oil absorbent at 50°.
