The present invention relates to automated waste recovering system and method which is not limited to a specific type of waste only. The system comprises a reactor for pyrolysis, a condensing unit connected to a water-cooled chiller to obtain liquid phase products and non-condensable gas, a gas treatment unit, a series of gas filtration unit to obtain clean gas, a storage and a control unit. The system also comprises a gas mixer unit to mix the non-condensable gas with hydrogen to obtain hydrocarbon rich gas, an artificial fuel condensing unit for condensing the hydrocarbon rich gas to obtain artificial fuel and water, which subsequently separated in a phase separator unit. The present invention provides a means to achieve constant yield by controlling conditions in the reactor and further increase the yield by producing artificial fuel.

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 base-stocks, 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.
