SKELETAL ISOMERISATION PROCESS FOR OLEFINS USING AN ALUMINA-BASED COMPOUND

摘要

THE INVENTION CONCERNS A PROCESS FOR THE SKELETAL ISOMERISATION OF N-OLEFINS CONTAINING 4 TO 20 CARBON ATOMS, CONSISTING IN BRINGING A FEEDSTOCK CONTAINING THE OLEFINS INTO CONTACT WITH A CATALYST PREPARED FROM AN ALUMINA-BASED COMPOUND WHICH IS TREATED WITH A POLYORGANOSILOXANE THEN HEAT TREATED. THE QUANTITY OF SILICA INTRODUCED IS GENERALLY BETWEEN 0.05AND 15BY WEIGHT.
