A system level analysis of pyrolysis of cotton stalk biomass

Abstract

In this study, a system level analysis of pyrolysis of cotton stalk biomass is carried out in ASPEN Plus software to analyze the conversion of such agriculture residue into bio-oil, biochar, and non-condensable gases. The liquid and solid components are considered as primary products, whereas gases are combusted in the presence of air to generate flue gases. The flue gases are utilized to provide heat energy for reaction and drying operations. The process plant scale model is found suitable to auto-thermally process 10 tonnes/day of any biomass feed and can be extended with comprehensive kinetics for analyzing the rate of formation of value-added chemical compounds, which can be separated and used for commercial applications.
