摘要

18 ISOMERIZATION OF BUTENE IN THE IONIC LIQUID-CATALYZED ALKYLATION OF LIGHT ISOPAR-AFFINS AND OLEFINS 5 ABSTRACT A PROCESS FOR PRODUCING ALLCYLATE COMPRISING CONTACTING A FIRST HYDROCARBON STREAM COMPRISING AT LEAST ONE OLEFIN HAVINA FROM 2 TO 6 CARBON ATOMS WHICH CONTAINS I - 1 0 BUTENE WITH AN ISORNERIZATION CATAIVST UNDER CONDITIONS FAVORINIZ THE ISOMERIZATION OF I -BUTENE TO 2-BUTENE SO THE ISOMERIZED STREAM CONTAINS A AREATER CONCENTRATION OF 2- BUTENE THAN THE FIRST HVDROCARBON STREAM AND CONTACTING THE ISOMERIZED STREAM AND A SECOND HYDROCARBON STREAM COMPRISING AT LEAST ONE ISOPARAFFIN HAVING FROM 3 ) TO 6 CARBON ATOMS WITH AN ACIDIC IONIC LIQUID CATALYST UNDER ALKYLATION CONDITIONS TO 1 5 PRODUCE AN ALKYLATE STREAM IS DISCLOSED.
