Herman A., Yusup S., Shahbaz M., 2016, Utilization of Bottom Ash as Catalyst in Biomass Steam Gasification for Hydrogen and Syngas Production, Chemical Engineering Transactions, 52, 1249-1254.
Coal bottom ash is used as the catalyst for biomass gasification of palm kernel shell using thermogravimetric analyzer coupled with mass spectrometer at operating temperature ranging from 650 °C to 750 °C. The objective of this study is to evaluate the gas composition of the biomass gasification using coal bottom ash as the catalyst. The produced hydrogen gas content is 36.57 vol% at temperature of 700 °C while the gas composition of carbon monoxide, carbon dioxide and methane are 24.73, 1.40 and 37.30 vol % respectively. In addition, it is found that the minerals exist in the coal bottom ash help to reduce the formation of carbon dioxide gas while promote the formation of methane in the product gas.
