Production Of Carbonium Ion Or Hydrocarbon Free-radical Patents (Class 585/942)
  • Patent number: 6258988
    Abstract: A method is disclosed for reforming organics into shorter-chain unsaturated organic compounds. A molten metal bath is provided which can cause homolytic cleavage of an organic component of an organic-containing feed. The feed is directed into the molten metal bath at a rate which causes partial homolytic cleavage of an organic component of the feed. Conditions are established and maintained in the reactor to cause partial homolytic cleavage of the organic component to produce unsaturated organic compounds, as products of the homolytic cleavage, which are discharged from the molten metal bath.

  • Patent number: 4784744
    Abstract: Disclosed herein is a process for stabilizing the liquid resulting from the thermal treatment of a hydrocarbon resid by coking, visbreaking or thermal cracking. The liquid product is contacted with a gaseous stream of hydrocarbons from an exterior source containing alkyl such as methyl CH.sub.3. free-radicals. The free radicals are derived by contacting methane, ethane, propane or a mixture thereof with a magnesia catalyst at a temperature of about 500.degree. C.

  • Patent number: 4162233
    Abstract: Novel acid systems are disclosed which are characterized as being capable of stabilizing high concentrations of tertiary cations, e.g., t-butyl cation, and further characterized as capable of forming carbonium ion salts containing both dimeric and monomeric anions. The ions undergo hydride and halide exchange with other alkanes and halides. The hydride transfer reaction renders them useful in isomerization and alkylation reactions.

  • Patent number: 4159939
    Abstract: Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a novel attenuated superative multimetallic catalytic composite comprising a combination of a catalytically effective amount of a pyrolyzed rhenium carbonyl component with a porous carrier material containing a uniform dispersion of catalytically effective amounts of a platinum group component, which is maintained in the elemental metallic state, and of a tantalum component. In a highly preferred embodiment, this novel catalytic composite also contains a catalytically effective amount of a halogen component. The platinum group component, pyrolyzed rhenium carbonyl component, tantalum component and optional halogen component are preferably present in the multimetallic catalytic composite in amounts, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum group metal, about 0.01 to about 5 wt. % rhenium, about 0.01 to about 5 % tantalum and about 0.1 to about 3.5 wt. % halogen.
