Abstract
A method for isomerizing alpha olefins to produce an isomerization mixture comprising branched olefins can comprise contacting an olefinic feed including one or more C10-C20 alpha olefins with a catalyst under skeletal isomerization conditions, wherein the catalyst comprises a molecular sieve having an MRE topology; and obtaining an isomerization mixture comprising one or more C10-C20 branched olefins.
Claims16
A method comprising:
- contacting an olefinic feed consisting essentially of C12-C14 alpha olefins with a catalyst under skeletal isomerization conditions, wherein the catalyst comprises a molecular sieve having an MRE topology, wherein the olefinic feed has an average carbon number from 12 to 14 and is supplied at a weight hourly space velocity (WHSV) of about 1 h−1 based on liquid reactive feed and zeolite content of the catalyst, and wherein the isomerization conditions comprise a temperature of about 170° C.;
- and
- obtaining an isomerization mixture consisting essentially of C12-C14 branched olefins.
A method comprising:
- contacting an olefinic feed consisting essentially of C12-C14 alpha olefins with a catalyst under skeletal isomerization conditions, wherein the catalyst comprises a molecular sieve having an MRE topology and comprises ZSM-48, wherein the olefinic feed is supplied at a weight hourly space velocity (WHSV) of about 1 h−1 based on liquid reactive feed and zeolite content of the catalyst, wherein the olefinic feed has an average carbon number from 12 to 14, and wherein the isomerization conditions comprise a temperature of about 170° C.;
- and
- obtaining an isomerization mixture consisting essentially of C12-C14 branched olefins.
