Abstract
Non-conventional energy sources based on biomass gasification for production of producer gas is a promising technique. However, the presence of unacceptable levels of biogasification tar waste puts the limit of its use. Although investigations are being carried out to study avenues for controlling the amount of tar produced during biomass gasification, the complete removal of this waste still remains a big challenge. Problems are severe when the waste comes to contact with water body leading to the leaching of components (pollutants) from tar into the environment. In this paper, we are reporting the study that has been carried out to investigate and evaluate the leaching properties of bio-gasification tar in water as a function of concentration levels, temperature and pH levels of the solvents.
