  • Catalytic/oxidative promoted hydrocarbon pyrolysis
    Patent number: 5866745
    Abstract: Light olefins are produced from a hydrocarbon feedstock by a steam pyrolysis reaction in the presence of small quantities of essentially pure oxygen and selected catalytic solids to enhance the steam pyrolysis reaction, to promote the combustion of hydrogen to water and to minimize the formation of carbon oxides. The catalysts are characterized by low surface area, by non-alumina supports and by the catalytic oxides of the group IVB, VB and VIB transition metals.

  • Production of halohydrins
    Patent number: 4479020
    Abstract: Production of halohydrins; in particular, chlorohydrins by reaction of tertiary alkyl hypohalite and olefinically unsaturated compound in the presence of water and a metal selected from Group II-A, II-B, III-A, III-B, IV-A, IV-B, or V-A of the Periodic Table. The use of such metals improves the production of halohydrin.
