waste plastic, thermal degradation, pyrolysis, and catalyst degradation
This project is about the recycling of plastic and converting it into the useful industrial fuels.so the dumping problem of the plastic is reduced and the pollution due to dumping of plastic can be reduced and also the use of petroleum fuels are replaced by this fuel and the other natural fuels are conserved.it is the simple process of doing catalytic cracking of plastic in absence of oxygen by pyrolysis process and doing distillation process to convert the plastic into crude oil carbon char and other useful gases. Plastic is an indispensable part of our daily life. Its production and consumption has been rising very rapidly due to its wide range of application. Due to its non-biodegradable nature it cannot be easily disposed of. So, nowadays new technology is being used to treat the waste plastic one of such process is pyrolysis. Under the pyrolytic and cracking conditions the plastic wastes can be decomposed into three fractions: gas. Liquid and solid residue. The waste plastics consisting of high density polyethylene (HDPE) was pyrolyzed in this study. The pyrolysis of plastic wastes produces a whole spectrum of hydrocarbons including paraffin’s. Olefins, naphthalene’s and aromatics. The liquid product yield is about 76% in all the cases. In thermal pyrolysis, the product obtained gets solidified but in catalytic cracking good liquid product can be obtained which can be used as fuel. This application is further combined with technologies of municipal plastic wastes collection, classification and pre-treatment at front end and product purification and testing at back end to determine the properties of the various products obtained.
