Abstract

Biomass tar is the major problem for biomass gasification that can create many problems in the system such as blockages, catalyst deactivation, and pipe corrosioncan be impact to producer gas as well. The tar removal system is necessary to assure in economic costand effective on fuel gas utilization. In this article, the catalytic activity of the Ni/Mg/Y-Zeolite as the upgraded catalyst was investigated in the removal of tar model compounds as toluene and naphthalene via microwave irradiation. The results foundedthat the tar treatment system via microwave irradiation which is low energy consumption, swiftly, and efficient has been successfully improved catalytic decomposition of tar models. The temperature of 900 °C can simply to assess within 20 minutesof irradiation under MW power at 0.7 kW, gas flow rate at 10 L/minand bed height of 12 cm. Ni/Mg/Y-Zeolite shows high catalytic activity due to lower coke deposited on catalyst surface compared with the previous study.
