PENGUJIAN AWAL TAR PADA UPDRAFT GASIFIER DENGAN TIGA GAS KELUAR DARI ATAS, REDUKSI DAN PEMBAKARAN

This study investigates the tar content in an updraft gasifier modified with three gas outlet channels, namely the upper channel, the reduction channel, and the combustion channel, using coconut shell biomass as the feedstock. The research is motivated by the large potential of biomass resources in Indonesia and the main drawback of updraft gasifiers, namely the high tar content, which can disrupt gasification system performance and limit the utilization of the produced gas. Tar is a complex mixture of high–molecular-weight organic hydrocarbon compounds formed during the pyrolysis and gasification of biomass. The research method employed was an experimental approach with three experimental runs. The parameters analyzed included gas volume, tar mass, and tar mass per unit volume of gas. The results show that the highest tar content was obtained from the upper channel, followed by the reduction channel, while the lowest tar content was produced from the combustion channel. The average tar mass per unit volume of gas in the upper channel ranged from 22 to 31 g/m³, in the reduction channel from 12 to 16 g/m³, and in the combustion channel around 1 to 2 g/m³. These results indicate that the high temperature in the combustion zone plays a crucial role in the tar cracking process. Overall, the modification of the gas outlet channels was proven to significantly reduce tar content and has the potential to enhance the utilization of gas produced from the gasification process.
