An Effect of Zeolite Size on Performance of Dry Scrubber in Tar Removal of Biomass Derived Syngas

Abstract

Increasing attention on the use of biomass derived syngas as internal combustion engine fuel, impacts on rising the demand of the scrubber for tar removal of the syngas. Wet scrubber is been used widely for this purpose. However, the liquid adsorbent containing tar may harmful when exposes to the environment. Thus to encounter the problem, the present work proposes the use of dry scrubber with zeolite as an adsorbent. The work aims to develop a simple and low cost zeolite scrubber and investigate and effect of zeolite size on performance of the scrubber for tar removal of syngas from biomass gasification. The result shows that zeolite size is proportional to specific area, heat transfer rate, and scrubber’s effectiveness. The highest scrubber’s effectiveness of 0.25 is obtained for the smallest zeolite size, i.e. 30 mm.
