(ii) decreasing the zeolite content of said catalyst composition or steaming the catalyst composition to decrease the Alpha
Value; and

(b) lowering said reactor pressure to about 370 psig (3102 kPa) or less or said alkylating agent feed supply pressure from
about 370 psig (3102 kPa) or less, wherein said Relative Activity is the percent temperature rise in an adiabatic pipe reactor
having one or more thermocouples divided by the percentage bed length based on the position of said thermocouples in said
reactor.

PROCESS FOR SEPARATING METHYLCYCLOPENTANONE FROM CYCLOHEXANONE

ExxonMobil Chemical Paten...

1. A process for separating methylcyclopentanone from a mixture comprising cyclohexanone and methylcyclopentanone, the process
comprising:
(I) providing a first feedstock comprising cyclohexanone and methylcyclopentanone, the methylcyclopentanone having a concentration
CMCP(1);

(II) including water in the first feedstock at a concentration CH2O(1) of at least 0.10 wt %; and
(III) fractionating the first feedstock in a first distillation column to obtain a first upper effluent rich in methylcyclopentanone
having a methylcyclopentanone concentration of CMCP(2) and a first lower effluent rich in cyclohexanone, wherein CMCP(2)/CMCP(1)>3.0.
