Abstract:
1. An integrated process for the production of paraffins and olefins from a feedstock selected from the group consisting of: i) gas oils obtained from the distillation at a temperature from 120° C. to 250° C. and a pressure from 7 Kpa to 13 KPa of heavy crude oil obtained from oil sands; and ii) a mixture of pyrolysis fuel oil distilled at a temperature from 750° C. to 900° C. and a pressure from 137 to 276 KPa from the heavy residues from the steam cracking of paraffins and gas oils obtained from the distillation at a temperature from 120° C. to 250° C. and a pressure from 7 Kpa to 13 KPa of heavy crude oil obtained from oil sands comprising: c) combining the said stream comprising from 30 to 70 weight % of one or more aromatic ring hydrocarbons and from 70 to 30 weight % of saturated hydrocarbons from gas oil and the stream from the middle to lower part of the column of the distillation of the pyrolysis fuel oil in a weight ratio from 1:10 to 10:1; d) processing the stream from step (c) in an integrated unit to reduce the sulphur content to less than 800 ppm by weight and the nitrogen content to less than 10 ppm by weight and saturate aromatic rings in the presence a catalyst selected from the group consisting of alkaline earth metal oxides and transition metal oxides of iron, copper, titanium, vanadium, chromium, nickel, molybdenum, tungsten, zirconium, ruthenium, platinum and palladium supported on a zeolite having a pore size of at least 7.4 Angstroms and a constraint index of less than 2; and e) subjecting the resulting stream to a ring cleavage in the presence of a zeolite having a pore size of at least 7.4 angstroms and a constraint index of less than 2 to produce mainly paraffinic petrochemicals feedstocks.
