3-2-4 Evaluation of clay catalysts for biomass fluid catalytic cracking gasification

Abstract

Huge amounts of biomass wastes is being generated in plantation sites in Indonesia. But there is no appropriate technology for the biomass wastes utilization, which can be acceptable by local communities. While a development of a highly-efficient biomass gasification process is required in Indonesia because of relatively high labor and transportation costs, in Indonesia the direction of development of the appropriate technologies are different due to the completely different situation such as relatively low labor but high catalyst costs. Based on the Indonesian circumstance, the authors proposed a biomass catalytic gasification process by clay catalysts. For this process, the authors aim at a development of gasification catalyst prepared from clay minerals, which has not so high activities but can enough reduce tar formation. The purpose of this study is to evaluate the catalytic activity of various clays which are available in the Indonesian field by lab-scale biomass steam gasification experiments.
