Abstract

Downdraft gasifier is one of the few techniques of gasification that can produce gas capable of generating mechanical and electrical power. The materials used for gasification come from biomass at a reasonable cost as the system used is ideal for small scale applications. The unique features of low tar production in gas produced by downdraft gasifier enable their use in engine and gas turbine systems without the need for major cleaning processes. For the purpose of improving the quality of the produced gas, the torrefaction process is required to lower the moisture of the biomass and increase the heating value. Current research investigates the quality of syngas produced using a downdraft gasifier. This gasification process compares the quality of syngas producedfrom several raw materials such as palm kernels (PKS), empty fruit bunches (EFB) and rubber seed pericarps (RSP). The results show that the torrefied PKS and EFB are more suitable for use with downdraft gasifier because the quality of the syngas and the LHV values obtained are better than those using the torrefied RSP.
