Process for upgrading a paraffinic feedstock

摘要

Process for upgrading a paraffinic feedstock which includes: a) supplying the feedstock and an olefins-containing stream at a paraffin to olefin volume ratio greater than 2 to a reactor containing a zeolite-beta catalyst; and b) removing the upgraded product; wherein the process is operated at an olefin conversion of at least 90 mol % in an external circulation reactor having an extent of external circulation of liquid reactor content expressed as (* CHEMICAL STRUCTURE *) of greater than 2 wherein (phi)/v is the volumetric flow rate of feedstock and olefins-containing stream and (phi)/vc is the volumetric external circulation flow rate, and upgraded products produced by the process.
