Waste Plastics Management

Catalytic Conversion of Plastic Wastes into Middle Distillate Products:

In this project Petrotex analyzed catalytic conversion of waste plastics such as polyethylene and polypropylene into oil and middle distillate products. The proportion of plastics mixture was based on United States plastic production rates.

In this process, the novel catalyst, made in the Research Center, was applied. The catalyst is a zeolite format that yields interesting results in producing benzene and gasoline due to its complex mixture of heavy metals and the way it is produced.

This study was conducted to obtain synthetic parameters of a semi-industrial plant designing and construction with high precision. The plant was constructed to convert waste plastics into benzene, gasoline and other similar products….

The results in this paper are obtained from more than 85 experimental tests that were carried out in Research Center of Abadan Institute of Technology in laboratory scale. The results obtained from the experiments illustrate that applying AIT100 catalyst would cause 1000 seconds decrease in reaction time to convert %99.5 of waste plastics into benzene and other distillate products; that is a giant step ahead of previous studies. Besides, similar studies that apply catalytic cracking of PE and PP polymers with the actual proportion of their production in the US have never been done before.  The catalyst also causes reduction of process temperature from 550-700 to 410-450. The results exhibit that about 51 percent of the plastics are converted into benzene range products. The obtained data represent that amount of produced liquid products is more than what other studies and catalysts had previously gained while the reaction duration is still short.
