ABSTRACT:
A process for the conversion of plastic to produce a synthetic crude oil by means of contacting the plastic with a hydrocarbonaceous recycle stream in a liquefying zone operated at liquefying conditions to produce a liquefied stream of plastic containing non-distillable particulate matter and at least a portion thereof is filtered. The filtered stream having a reduced concentration of finely divided particulate matter and the balance, if any, of the original liquefied stream together with hydrogen is contacted with a hydro-demetallization catalyst in a hydro-demetallization zone at hydro-demetallization conditions to produce gaseous, water-soluble inorganic compounds. The effluent from the hydro-demetallization zone is contacted with a hydrocracking catalyst in a hydrocracking zone to produce lower boiling hydrocarbons suitable for use as a synthetic crude oil. A recovered hydrogen-rich gaseous stream is preferably recycled to the hydro-demetallization zone. The gaseous, water-soluble inorganic compounds are removed by scrubbing the hydrocracking zone effluent with an aqueous stream. A portion of the hydrocarbons recovered from the hydrocracking zone effluent is recycled to the liquefying zone.
