Extraction Of Bio-Fuel Through Pyrolysis

Abstract

Energy is the key of globalization. As the world population and economy grow, higher consumption results in higher waste packaging ,plastic and paper residues. Pyrolysis offers a way to recover fuels and other chemical from this fraction. By applying heat to these feedstock into more valuable products in the forms of gas, liquid and char. The main objective of this study were to understand and optimize the processes of waste plastic and rice husk pyrolysis. Pyrolysis of polyethylene (PE), polypropylene (PE), polystyrene (PS), cellulose, lignin, silica and moisture has been investigated both theoretically and experimentally in a pyrolysis reactor. The key factor have been investigated and identified. The cranking temperature for the PE and PP in the pyrolysis is at 450 degree C, but that of PS is lower at 320 degree C, cellusole is 410 degree C, lignin is 405 degree C and silica is 700-1100 degree C. High reaction temperature and heating rate can significantly promote the production of light hydrocarbons. Long residence time also favours the yield of the light hydrocarbon products. The effects of other factors like type of reactor, catalyst, pressure and reflux rate have also been investigated in the literature review
