Patent number: 4629718Abstract: A class of mixed oxide catalysts comprising Mn-containing oxides, alkali metals or compounds thereof, and at least one member of the group consisting of oxides of Si, oxides of alkaline earth metals, and mixed oxides of Si and at least one alkaline earth metal. In the more preferred embodiments, the third component serves as a carrier for the Mn and alkali metal components. The composition preferably comprises a major amount of the carrier material and minor amounts of the other components. The compositions are useful for hydrocarbon coversion, methane conversion, and oxidative dehydrogenation processes characterized by formation of coproduct water.Type: GrantFiled: December 18, 1984Date of Patent: December 16, 1986Assignee: Atlantic Richfield CompanyInventors: C. Andrew Jones, John J. Leonard, John A. Sofranko, Howard P. Withers, E. William Breder, Jr., Marvin F. L. Johnson, John A. Jaecker

Patent number: 4311582Abstract: Thermal stability of a halide-promoted, supported noble metal reforming catalyst is improved by employing a modified alumina support whose alumina precursor comprises at least about 75 weight percent boehmite, having an average crystallite diameter no greater than about 60 Angstroms. The thermal stability of the support is improved by the inclusion of a minor amount of silica, preferably added as an alkali-metal silicate to a mull of alumina prior to its extrusion and calcination with subsequent washing to remove the alkali metal.Type: GrantFiled: October 2, 1980Date of Patent: January 19, 1982Assignee: Atlantic Richfield CompanyInventors: Marvin F.
