Abstract
This invention relates to a process for reducing the Bromine Index of a hydrocarbon feedstock having less than 5 wppm oxygenates-oxygen, comprising the step of contacting the feedstock with a catalyst at conversion conditions to form a first effluent, wherein the catalyst includes a molecular sieve having a zeolite structure type of MWW.
Claims16
A process for reducing the Bromine Index of an aromatic hydrocarbon feedstock, comprising the steps of:
- (a) pretreating said feedstock with a catalyst or absorbent to reduce oxygenates-oxygen in said feedstock to less than 5 wppm;
- and
- (b) contacting said pretreated feedstock with a catalyst to form a first effluent,
- wherein said catalyst in step (b) includes a molecular sieve having a zeolite structure type of MWW;
- then
- (c) passing said first effluent from step (b) to a para-xylene production process.
