  • Patent number: 4419220
    Abstract: Hydrocarbon feedstocks such as distillate fuel oils and gas oils are dewaxed by isomerizing the waxy components over a zeolite beta catalyst. The process may be carried out in the presence or absence of added hydrogen. Preferred catalysts have a zeolite silica:alumina ratio over 100:1.
    Type: Grant
    Filed: May 18, 1982
    Date of Patent: December 6, 1983
    Assignee: Mobil Oil Corporation
    Inventors: Rene B. LaPierre, Randall D. Partridge, Nai Y. Chen, Steven S. Wong
  • Patent number: 4247386
    Abstract: A catalytic process for hydrocracking C.sub.5.sup.+ hydrocarbons or mixtures thereof into a C.sub.2 -C.sub.5 mixture paraffin stream in the presence of a palladium/Group IIA, e.g. Be Mg, or IIIB, e.g. Sc, Y, ZSM-20 hydrocracking catalyst, and thermally cracking this mixture to recover ethylene and propylene.
    Type: Grant
    Filed: August 6, 1979
    Date of Patent: January 27, 1981
    Assignee: Mobil Oil Corporation
    Inventors: Rene B. LaPierre, Vern W. Weekman
  • Patent number: 4231955
    Abstract: A method is provided for synthesizing alkylnitriles and alkylaminonitriles by reacting formaldehyde, a C.sub.1 -C.sub.5 monohydric alcohol and a compound having the formula R.sub.1 R.sub.2 NH where R.sub.1 and R.sub.2 are selected from the group consisting of hydrogen and alkyl groups containing 1 to 5 carbon atoms under effective conditions in the presence of a catalyst comprising a crystalline aluminosilicate zeolite having a silica to alumina ratio of at least about 12 and a constraint index within the approximate range of 1 to 12 and recovering from the resulting reaction mixture, a product containing at least one of the above nitrile compounds.
