Design, fabrication and performance test of a fixed bed batch type pyrolysis plant with scrap tire in Bangladesh

Abstract

This paper presents the design and construction of a fixed bed batch pyrolysis reactor. The reactor is further used for the production of pyro oil from scrap tire. The result shows that reactor yields a maximum pyro oil of 42 wt% at the temperature of 400 °C with a feed size of 15 cm3. The produced pyro oil has a higher viscosity of 4.5 cSt and heating value of 42.5 MJ/kg. Thus pyro oil cannot be used directly in engine operation but as a furnace oil or fuel in boiler operation. The char is potential for using as a fertilizer, production of conveyor belt and footwear. Keywords: Design and fabrication, Fixed bed, Pyrolysis, Scrap tire
