Tar and Particulate Matters Removal from Producer Gas by using Oily Organic Filter Media
Abstract:
The present study showed that the quality of producer gas obtained by thermo-chemical conversion of crop residues varied due to organic nature of biomass and the variation in operating parameters such as equivalence air fuel ratio and superficial velocity. The range of tar and particulate matters (TP) in producer gas obtained from downdraught gasifier generally varied from 110-14000 mg/Nm3, which makes it unsuitable for internal combustion (IC) engine operation. Hence, a reduction in TP below 150 mg/Nm3 is necessary for long run engine operation. Controlling operating parameters is a very sophisticated process and can be applicable only in laboratory experiments. Therefore, improvement in physical cleaning process to reduce TP and improve producer gas quality is very important for sustainable IC engine operation. The experiments were conducted by mixing jatropha oil with saw dust and wood shavings as filter media with the existing cooling and cleaning train (version 6). Result showed a reduction of TP (< 150 mg/Nm3) value in the range of 12-17 mg/Nm3, which was much below the recommended limit of TP as prescribed by Ministry of New and Renewable Energy, Government of India for engine operation.
