Bioenergy is the prominent source of generation of power by means of thermal and electricity route. The potential of biomass, a renewable energy source, is estimated to be 500 million metric tons per year in India. Gasification, a promising route to extract energy from biomass, is a thermochemical process having high thermal efficiency compared to direct combustion. Producer gas is the outcome of gasification. Producer gas is a medium calorific value gas and is rich in H2 and CO. Despite innumerable applications of the biomass gasification gas, this century-old technology is yet not in its mature form. This is because of impurities like tar and particulate matter (PM). Tar is condensable at the downstream of gasifier system and leads to clogging or blockage in the process equipment. PM can create problems like fouling and corrosion. In this review paper, various methodologies are discussed which can diminish or destruct tar and PM. The purpose of this review is to analyze the recent technologies to clean the producer gas. Various gas cleaning methods like physical, non-catalytic, and catalytic are also discussed. The findings of the review are that catalytic tar conversion has the potential to increase conversion efficiencies while simultaneously decreasing tar, and therefore it is an instinctively effective method to obtain clean gas.
