  • Catalyst prepared by a particular preparation method and its use in a process for preparing tertiary olefins from alkyl-tert-alkylethers
    Patent number: 5214018
    Abstract: A catalyst for producing tertiary olefins from alkyl-tert-alkylethers is described, consisting of silica modified by adding alumina in a quantity of between 0.3 and 1% by weight with respect to the silica, and is prepared by a method consisting essentially of impregnating a silica with a solution of aluminium salts, followed by drying and calcining, the material then being subjected to purification treatment with aqueous acid solutions or with aqueous solutions which release acidity by thermal decomposition, followed by washing, a second drying and a second calcining.

  • Olefin bond isomerization process
    Patent number: 4814542
    Abstract: A process for olefin bond isomerization by means of a gamma alumina-based catalyst containing SiO.sub.2 and oxides of a metal chosen from those of Group II A and/or VIII and/or III B and/or Lanthanides, with particular molar ratios between the various oxides. The catalyst is thermally stable, and in the conversion of butene-2 to butene-1 enables butene-1 to be obtained with an isobutene content below the allowable limits for butene-1 grade polymerization.
