  • Process for Using Iron Oxide and Alumina Catalyst with Large Particle Diameter for Slurry Hydrocracking
    Publication number: 20090321314
    Abstract: A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. Performance of the iron oxide and alumina catalyst at high mean particle diameters is comparable to performance at low mean particle diameters.

  • Slurry Hydroconversion of Biorenewable Feedstocks
    Publication number: 20090299112
    Abstract: A method for hydroconversion of a combined feed of at least one low value petroleum derived hydrocarbon and at least one biorenewable feedstock in a hydroconversion reaction zone in the presence of a hydroconversion catalyst at hydroconversion reaction conditions for a period of time sufficient to form a hydroconversion reaction product.

  • Modified PT/RU catalyst for ring opening and process using the catalyst
    Patent number: 7345214
    Abstract: A catalyst for opening naphthenic rings has been developed. The catalyst comprises ruthenium and platinum as the active catalytic metals and a modifier with cerium being a preferred modifier. At least 50% of the platinum and ruthenium components are present as particles wherein more ruthenium is present on the surface of the particles than in the center. All of these components are dispersed on a metal oxide support such as aluminas. A ring opening process using the catalyst is also described.

  • Middle distillate selective hydrocracking process
    Patent number: 7048845
    Abstract: Increased yields of middle distillate products are obtained in a hydrocracking process by the use of a catalyst containing a Beta zeolite which has been hydrothermally treated to adjust the distribution of relatively weak and strong acid sites. The number of strong acid sites is reduced, preferably by steaming at a temperature above 750° C. for at least one hour, with the acidity distribution being measured by pyridine IR adsorption values taken at 150° C., and 300° C., and 450° C.

  • Process for treating a non-distillable halogenated organic feed stream
    Patent number: 5817288
    Abstract: A process for treating a non-distillable halogenated organic feed stream wherein the feed stream is contacted with a hydrogen-rich gaseous stream at hydrodehalogenation conditions to produce a carbonaceous solid containing a reduced halogen content and hydrogen halide gas. The resulting carbonaceous solid is stripped with a second hydrogen-rich gas to recover additional hydrogen halide gas and to produce a carbonaceous solid which is suitable for other uses.

  • Olefin isomerization process
    Patent number: 5365008
    Abstract: An improved process is disclosed for the isomerization of butenes and/or pentenes using a catalyst comprising a silicoaluminophosphate molecular sieve containing noncondensed silica. It is of particular interest to increase the proportion of olefins containing tertiary carbons in the product with low formation of undesirable by-products. Product olefins may be further processed to obtain ethers, which enjoy high current interest as components for reformulated gasoline.
