PROCESS FOR THE ISOMERISATION OF OLEFINES

摘要

Process for isomerizing linear ethylenic hydrocarbons to branched ethylenic hydrocarbons having the same number of carbon atoms in the molecule, in the presence of steam and of a catalyst containing alumina, silica and a metal or compound of a metal selected from chromium, palladium, nickel, copper and silver at critical concentrations of silica and of metal, and with a critical proportion of water with respect to the hydrocarbons.
