Influence of Pretreated Palm Kernel Shell and Mukah Balingian Coal on Co-gasification

Abstract
In this study, co-gasification of palm kernel shell (PKS) and Mukah Balingian (MB) coal was carried out in a fixed bed reactor. The effect of sample pretreatment of both samples were explored via co-gasification towards product yields and gases composition. Results indicated that, pretreated blended samples produced higher gas yield and lower tar and char yield than the untreated blended samples. This was due to low moisture and oxygenated components of the pretreated samples prior to gasification. The pretreated blending also produced the highest H2, the lowest CO and CO2 composition. Blending of pretreated PKS with untreated MB coal exhibited slight improvement than blending of untreated sample. As a whole, pretreated of both samples (PKS and MB coal) performed to have prominence influence on the distribution and composition of product yields through co-gasification.
