Title: EXPERIMENTAL STUDY OF EFFECT OF PRESSURE ON PYROLYSIS OF BIOMASS
Abstract: Pyrolysis is thermal treatment of solid waste in the absence of an oxidizing agent (in inert atmosphere) which generally yields three products namely pyrolysis-oil (liquid), char (solid residue) and gas.The products obtained in pyrolysis can be further used as energy source.Rice husk and saw dust are considered as solid wastes in this study.The effect of temperature and pressure on pyrolysis was studied in a fixed bed reactor.The experimental runs were performed in nitrogen atmosphere.The temperature was varied from 300°C to 500°C, while the operational pressure was fixed at 4 bar, 7 bar and 10 bar.The products such as solid char, liquid pyrolysis oil and syngas were obtained.The solid char was characterized by CHNS analysis, while the pyrolysis oil was characterized by FTIR analysis,
