Process for upgrading a paraffinic feedstock

摘要

Process for upgrading a paraffinic feedstock comprising: a) supplying the feedstock and an olefins-containing stream at a paraffin to olefin ratio greater than 2 v/v 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 $wherein\; phi\; v\; is\; the\; volumetric\; flow\; rate\; of\; feedstock\; and\; olefins-containing\; stream\; and\; phi\; vc\; is\; the\; volumetric\; external\; circulation\; flow\; rate,\; and\; upgraded\; products\; produced\; by\; the\; process.$
