Abstract

In this paper, the catalytic effects of two different biomass-derived ash catalysts, chicken dropping compost ash (CCA) and empty
fruit bunch ash (EFBA) on the performance of CO2 gasification of Loy Yang brown coal (LY) char were studied. The CO2 gasification
was done at temperatures between 650 to 800 oC. It was found that the reaction rate is strongly dependent on the CO2 gasification
temperature and the carbon conversion increases by increasing the CO2 gasification temperature. By using LY mixed with 10 wt%
of EFB ash (EFBA), the maximum char conversion of 1.0 with a high gasification rate was obtained when CO2 gasification was
carried out at 800oC for 30 min. Finally, the EFBA is more efficient in catalytic activity compared to the CC ash (CCA) under the same
conditions.
