Alkylation of organic aromatic compounds in a dual bed system |
| abstract |
CUMENE IS PRODUCED IN A CATALYTIC DISTILLATION COLUMN REACTOR (10) HAVING AN UPPER BED OF OMEGA (12) TYPE MOLECULAR SIEVE CATALYST AND A LOWER BED OF Y TYPE MOLECULAR SIEVE CATALYST. BENZENE AND PROPYLENE ARE REACTED IN THE UPPER BED (12) WHERE THE OMEGA TYPE SIEVE IS MORE SELECTIVE TO CUMENE THAN THE Y TYPE SIEVE. PART OF THE REACTION MIXTURE FLOWS DOWN THE COLUMN TO THE Y BED WHERE BENZENE REACTS WITH ANY UNREACTED PROPYLENE TO PRODUCE CUMENE. BENZENE REACTS WITH DIPROPYLBENZENE IN THE Y BED TO PRODUCE MORE CUMENE.CUMENE IS RECOVERED AS BOTTOMS PRODUCT AND UNREACTED BENZENE RECOVERED AS OVERHEADS (5) WHERE IT MAY BE RETURNED AS REFLUX TO THE COLUMN (10).(FIG 1) |
