The Removal of Mixed Tar in Biomass Fuel Gas through the Thermal and Catalytic Treatment Methods: Review

Abstract

The global situation consumes enormous amount of energy while the energy sources are limited and decreasing. Alternative energy source is widely focused for compensating the main energy source. Thus, the finding of alternative resources particularly biomass energy is highly essential. Biomass gasification is a transforming process of solid biomass into the valued fuel gases. Although biomass fuel gas provides utility gases, the contaminant as tar that need to eliminate for evading the problems to engines and turbines. Hence, the treatment methods of tar are extremely important and challenge. This paper indicates the recent treatment researches for biomass tar removal. The problems of tar as well as the weakness and advantages of all tar treatment methods are discussed.
