Abstract
Hydrocarbons capable of undergoing skeletal rearrangement or double bond shift are isomerized by contact with zirconia having hydrogen atoms in surface hydroxyl groups capable of ionizing and exchanging which has been treated with an ionic solution of a salt of Al or In such that 0.1 to 3% of the latter are incorporated into the surface of the ZrO2. The zirconia may be prepared conventionally and may have a surface area greater than 200 sq.m./gm. Reaction conditions may be:-Temperature 50-600 DEG C. L.H.S.V. 0.1 to 20 vol./vol. Suitable feedstocks include 3:3 dimethyl butene-1,4-methyl pentene-1 and butene-2. In an example the products from 4-methyl pentene-1 are cis and trans-3 and 4-methyl pentene-2, and 2-methyl pentene-1 and 2.ALSO:Zirconia having hydrogen atoms in surface hydroxyl groups capable of ionizing and exchanging is treated with an ionic solution of a salt of Al or In such that 0.1 to 3% of the latter are incorporated into the surface of the ZrO2. The zirconia may be prepared conventionally and may have a surface area greater than 200 sq. m./gm. In an example, zirconyl nitrate is treated with caustic soda to precipitate ZrO2; the latter is washed, dried and calcinated at 500 DEG C. Catalysts containing 0.18% Al and 0.72% In on ZrO2 are prepared by allowing ZrO2 to stand in M/10 sulphate solutions overnight, followed by exhaustive extraction.ALSO:Zirconia having hydrogen atoms in preface hydroxyl groups capable of ionizing the exchanging is treated with an ionic solution of a salt of Al or In such that 0.1 to 3% of the latter are incorporated on to the surface of the ZrO2. The zirconia may be prepared conventionally and may have a surface area greater than 200 sq.m./gm. In an example zirconyl nitrate is heated with caustic soda to precipitate ZrO2; the latter is washed, dried and calcined at 500 DEG C. Catalysts containing 0.18% Al and 0.72% In on ZrO2 are prepared by allowing ZrO2 to stand in M/10 sulphate solutions overnight, followed by exhaustive extraction.
