Title: METHOD OF PREPARATION OF HYDROCARBON FUELS FROM POLYOLEFIN WASTE MATERIALS
Abstract:
Method of producing hydrocarbon fuels from polyolefin waste materials, wherein: polyolefin waste materials are subjected to continuous depolymerisation in a tower flow reactor with a movable packing, which comprises a heating system for heating the lower half of the reaction chamber, where products of depolymerisation are collected in a gaseous state through an outlet in the upper half of the reaction chamber; and the obtained products of depolymerisation are subjected to catalytic hydrogenation and isomerisation in an atmosphere of synthesis gas, under atmospheric pressure, to obtain a mixture of hydrocarbon fuels; characterised in that: polyolefin waste materials are mixed with heated elements constituting the packing of the reactor until the surface of the packing elements is coated with a thin layer of plasticised material, wherein in the depolymerisation process the obtained mixture is fed as a stream into the reaction chamber from the top of the chamber, whereas a synthesis gas is fed in a counter current from the bottom, the gas comprising carbon monoxide (CO) and hydrogen (H2) with the molar ratio CO:H2 being from 0.25 to 1.5 : from 0.5 to 3.
