Co-gasification characteristics of palm oil by-products and coals for syngas production
E-mail:,
Large amounts of empty fruit bunches (EFB) are generated annually during the palm oil manufacturing process; however, they are still treated as waste. In this study, gasification experiments were conducted using EFB in a fluidized bed reactor (throughput=1 kg/hr) at an experimental temperature range of 700 to 1,000 °C to assess the use of EFB as a renewable energy resource. To overcome the issues of an unstable EFB supply, co-gasification experiments using EFB with coal were conducted. The resulting syngas yield was approximately 70 vol%, similar to that from EFB gasification. The heating value of syngas was a magnitude of three-times higher than that of EFB gasification. However, the dry gas yield and cold gas efficiency were lower than those of EFB gasification. A coal mixing rate of 20 wt% and 0.6 of ER would be appropriate conditions for continuous production of stable syngas.
