PENGUJIAN TAR PADA PROSES GASIFIKASI UPDRAFT GASIFIER DENGAN GAS KELUAR DARI DAERAH REDUKSI DAN DARI BAWAH

---

ar is a byproduct formed in the biomass gasification process due to the pyrolysis reaction of hydrocarbon compounds. The presence of tar in the gasification gas is a serious problem because it can clog the gas flow channel, reduce system efficiency, and disrupt the performance of advanced equipment. Therefore, efforts are needed to reduce the tar content to improve the quality of the gas produced by biomass gasification. This study aims to analyze the tar content in the coconut shell biomass gasification process using a modified updraft gasifier with two gas outlet paths, namely from the reduction zone and the bottom (combustion zone). Tar was collected using a gravimetric method with an impinger system and acetone solvent, then calculated the total weight and concentration per unit volume of gas. The results showed that the tar content in the reduction channel was much higher than the bottom channel, which was 69.16–81.16 g/m³, while in the bottom channel it was only 0.33–0.50 g/m³. This difference indicates that high temperatures and the presence of oxygen in the combustion zone play an important role in the cracking and oxidation processes of tar. Visual analysis also reveals a clear difference in character, with tar from the reduction channel being denser and thicker than tar from the combustion channel, which is thinner. Therefore, gas extraction from the bottom effectively reduces tar and improves gas quality, making it potentially applicable to small- to medium-scale biomass energy systems.
