Abstract
Syngas from biomass gasification is being developed for alternative feedstock in the chemical industry. Palm ker-nel shell which is generated from palm oil industry can be potentially used as raw material for gasification pro-cess. The purpose of this study was to investigate the use of modified natural zeolite catalysts in steam gasifica-tion of palm kernel shells. Mordenite type zeolite was modified by acid leaching to be used as a tar cracking cata-lyst. Steam gasification was conducted at the temperature range of 750-850 °C and the steam to biomass ratio was in the range of 0-2.25. The result showed that steam gasification of palm kernel shell with the addition of zeo-lite catalyst at 750 °C and steam to biomass ratio 2.25 could reduce tar content up to 98% or became 0.7 g/Nm3. In this study, gasification of palm kernel shells produced syngas with the hydrogen concentration in the range of 52-64% and H2/CO ratio of 2.7-5.7.
