CATALYTIC PRODUCTION OF DIESEL-LIKE OILS FROM PLASTIC WASTE

[Category : - RENEWABLE ENERGY]
[Viewed 217 times]

In short, a proprietary catalyst was developed to convert plastic waste to diesel fuel at very high purity in a single step using the pyrolysis process.

A dewaxing catalyst was prepared through the dissolution of nickel oxide and tungsten powders in an aqueous medium, followed by the impregnation of a ZSM-5 substrate and calcination at 500 °C. The synthesized catalyst was used in conjunction with a pyrolytic reactor running at a set point of 360 °C to break down a mixture of plastic grocery bags. The catalyst was found to be selective to the C9 - C22 isomers typical of diesel No. 2. Gas chromatographic analysis indicated the fraction of C24 and heavier components in the pyrolysis product was only 1.0%.
