Pyrolysis of Solid Wastes

Abstract

Pyrolysis of solid wastes like papers, rags, garden wastes, used tea leaves and municipal solid waste (MSW) is carried out in a fixed bed reactor for studying distribution of energy in pyrolytic products and their possible applications as fuel. Pyrolysis is conducted between 450°C to 650°C and at different reaction times. The temperature of 600°C is found to be good forgetting maximum yield of tar and is enhanced from 16 per cent to 27.6 per cent as the pyrolysis time reduces from 35 min to 5 min. The average yield of char and gas is found between 30-34 per cent and 16-20 per cent respectively, irrespective of reaction time. The

calorific values of solid, liquid and gaseous products of pyrolysis of all the wastes show a good fuel potential. The tar can be used as furnace oil, char can be utilized as a feedstock for producing active carbon and gas as a fuel for industrial furnaces or internal combustion engines.
