  • Patent number: 7144498
    Abstract: Supercritical conversion of hydrocarbons boiling above 538° C. (1000° F.) with a solvating hydrocarbon at a weight ratio of solvating hydrocarbon to high-boiling hydrocarbons of at least 2:1 and at conditions above the critical temperature and pressure of the high-boiling hydrocarbons-solvent mixture, in the presence of hot fluidized solids. The hydrocarbons are supplied to a reaction zone at a temperature below that of the hot solids supplied thereto, whereby the resulting hydrocarbons-solids suspension has a thermal equilibrium temperature corresponding to the reaction temperature. The conversion has high rates of sulfur, nitrogen and metals removal, nearly complete conversion to lower molecular weight products, high naphtha and distillate selectivity, and low coke formation.

  • Patent number: 6332975
    Abstract: The invention is a process for making anode grade coke which comprises solvent deasphalting a residue feedstock to obtain an essentially asphaltene-free, resin-containing stream and coking the resin-containing stream in a delayed coker to make anode coke. The solvent deasphalting can make a deasphalted oil stream containing resin or separate deasphalted oil and resin streams. There can be hydrotreating of (1) a minor portion of the residue feedstock wherein the hydrotreated residue is fed to the delayed coker with the resin-containing stream, (2) the resin-containing stream wherein the hydrotreated resin stream is fed to the delayed coker, or (3) a major portion of the residue feedstock wherein the hydrotreated residue is fed to the solvent deasphalting unit.

  • Patent number: 4534855
    Abstract: Trace metals, particularly As, Fe and Ni, are removed from hydrocarbonaceous oils, particularly shale oil by contacting the shale oil with quadrolobe alumina with or without a processing gas such as hydrogen or nitrogen at 500.degree. F. to 800.degree. F. at 250 to 750 psig and LHSV of 0.4 to 3.0 to deposit a portion of said trace metal onto said alumina and recover an oil product having substantially reduced amounts of trace metal.
