Experimental Optimization of Process for the Thermo-catalytic Degradation of Waste Polypropylene to Liquid Fuel
並列摘要
Waste polypropylene was cracked thermally and catalytically in the presence of kaolin clay in a batch reactor in the temperature range 400-550℃ in order to obtain suitable liquid fuels. The dependencies of process temperature, effect of catalyst, feed composition on yield of the fuel fraction were determined. It was observed that up to 450℃, the major product of thermal pyrolysis was liquid oil and the major products at other higher temperatures (475-550℃) are either viscous liquid or wax. The highest yield of pyrolysis liquid product was 82.85% by weight at 500℃. Use of kaolin as catalyst decreased the reaction time and increased the yield of liquid fraction. Again, the major pyrolysis product in catalytic pyrolysis i.e. the liquid fraction at all the temperature was low viscous liquid oil. The maximum oil yield using kaolin to plastic ratio 1:3 was 87.5% at 500℃. The oil obtained in this process was analyzed using FTIR and GC-MS for its composition. Fuel properties of the oil studied by IS methods are identical with the different petro fuels. On the basis of the obtained results, hypothetical continuous process of waste polypropylene plastics processing for engine fuel production can be presented.
