  • Patent number: 4840725
    Abstract: An improvement in the conversion of high boiling liquid organic materials to low boiling materials, and more particularly, in the process of converting heavy hydrocarbon oil feedstocks to fuel range liquids is described. In its broadest aspects, the invention comprises a process for converting high boiling hydrocarbons to lower boiling materials characterized by an increase in aromatic content and a lower pour point which comprises contacting said high boiling hydrocarbons with water at a temperature of from about 600.degree. F. to about 875.degree. F. at a pressure of at least about 2000 psi in the absence of any externally supplied catalysts, and wherein the weight ratio of water to high boiling hydrocarbons is from about 0.5:1 to about 1:1, and the water and high boiling hydrocarbon form a substantially single phase system under the elevated temperature and pressure conditions utilized.

  • Patent number: 4594141
    Abstract: A process for the conversion of high boiling saturated organic materials is described. The method comprises contacting said high boiling organic materials at a temperature of at least about 300.degree. C. and at a reaction pressure of at least about 2000 psi with an aqueous acidic medium containing at least one olefin, and a halogen-containing compound selected from the group consisting of a halogen, a hydrogen halide, a compound which can form a halide or a hydrogen halide in the aqueous acidic medium under the process conditions, or mixtures thereof whereby the high boiling organic material and aqueous acidic medium form a substantially single phase system. Optionally the process can be conducted in a reducing atmosphere. The process of the invention is useful for producing and recovering fuel range liquids from petroleum, coal, oil shale, shale oil, tar sand solids, bitumen and heavy hydrocarbon oils such as crude oil distillation residues which contain little or no carbon-carbon unsaturation.
