A METHOD FOR PREPARING A CATALYST BASED ON GAMMA ALUMINA STABILIZED BY SILICA |
摘要 |
A process for olefin bond isomerization by means of a gamma alumina-based catalyst containing SiO2 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. |
