Abstract (en)

A process for production of useful hydrocarbon materials from plastic waste and reaction system therefor is provided. The process includes frequentatively thermolyzing of high molecular weight hydrocarbons such as plastic waste to produce useful medium molecular weight hydrocarbons and low molecular weight hydrocarbons. The process utilizes low molecular weight hydrocarbons as solution reactants which helps in reducing the viscosity of the material for more effective heat transfer. The process also includes addition of one or more low molecular weight olefins and solution reactants to high molecular weight hydrocarbons to augment the free radical environment. The process also includes hydrogenating and oxidizing the high molecular weight hydrocarbons. The process enables production of the useful, predominantly hydrocarbon materials such as waxes, lube oil basestocks, refinery feedstocks, intermediates or fuel additives. The present invention also provides a reaction system comprising thermolysis reactor including a primary zone and an optional secondary zone for production of useful hydrocarbon materials from plastic waste.
