Extraction of Pyrolytic Fuel from Nonbiodegradable Solid Waste

Abstract

Under the project work waste tire and tube of bicycle/rickshaw were converted to useful fuel oil by the process of pyrolysis. In doing so fixed bed lire tube heating pyrolysis technology has been applied. Thermal pyrolysis is one of the renewable technologies where waste tire and tube were pyrolysed into fuel oil, carbon black, and combustible gas under the action of reasonable technological conditions. This technology could not only reasonably and effectively dispose waste tire and tube without pollution, but also is effective in producing fuel that can reduce energy crisis. In the present work, thermal pyrolysis of waste bicycle tire and tube were carried out in a batch reactor made up of mild steel within the temperature range of 300°C to 600°C. The optimum pyrolytic oil of 45.29% by weight was obtained at 450°C for tire and 43.89% by weight for tube at 550°C. A higher temperature and smaller particle size increase the heating rate resulting in a decreased char yield. The cracking of the hydrocarbons with an increase of the hydrogen content in the gaseous product is favored by a higher temperature and by using smaller particle size. The residence time is another vital parameter of the converting process. The effect of raw materials on the production of pyrolytic fuel is also studied. The physical properties of the oil obtained were determined. After proper treatment these oil can be used as substitute of alternative fuel.
