Polystyrene Plastic Waste into Liquid Fuel Using Silica-Alumina Catalyst, Extracted from Rice Husk
Abstract: Catalytic Pyrolysis of Polystyrene (PS) into fuel like products using silica alumina catalyst that was extracted from rice husk was investigated over temperature range of 430–470°C. The output of catalytic pyrolysis was liquid oil, solid residues (char) and gaseous fraction. The product yields as a function of temperature, time and catalyst amount were studied. High conversion of liquid (48.8%) was achieved at 430 and 450ºC in the presence of 12.5 …

Recovery of Liquid Hydrocarbon Fuels from Polypropylene Waste Plastics via Catalytic Pyrolysis
Abstract: Process of pyrolysis is a thermo-chemical method conducted at high temperatures and usually in presence of catalysts. Dissimilar type of natural and synthetic catalysts are used for alteration of organic wastes into cherished fuels. The aim of this work is conversion of waste production of liquid fuel using catalyst that produced from rice husk ash. Waste plastic was pyrolyzed at temperature range 430-470oC and obtained products were liquid fuel, gas …
