Increase of volumes of polymeric products consumptionleads to accumulation of non-decaying waste. Each year world population producesan enormous mountain of waste – about 400 million tons. It consists mostly ofpolymeric and plastic waste. Large part of polyethylene terephthalate (PET),polyethylene (PE) and other polymers waste is either buried into the ground orincinerated, which is unreasonable from financial point of view, and even harmful interms of ecology. The issues with recycling of PET bottles and PE plastic bags areremaining unsolved due to lack of original and non-expensive technologies ofreprocessing.As a solution for the problem, we have developed a technology of different kindplastic waste recycling by means of joint hydrocracking with fuel oil in presence ofcatalyst, resulting in motor fuels production.After hydrocracking of fuel oil with PE, petrol with octane number of 60-67 points,contains 0-0.3% of benzene, and acts as a high-quality raw material for reforming.Cetane number of diesel fraction is about 53.3-54 points.As a result of hydrocracking, PE and PET are depolymerized into simpler nontoxiccompounds, and their mixture is further processed in presence of catalyst,together with fuel oil products, resulting in fuel fractions output. Light fractions yield atfuel oil hydrocracking with addition of polymers reaches about 90%, ascompared with70% yield without polymers under the same conditons.140
