Process to alkylate an aromatic with a dilute stream comprising propylene and ethylene |
摘要 |
The present invention provides a method comprising (a) contacting a first reaction mixture comprising an aromatic and a dilute stream comprising ethylene and propylene with a large pore microporous solid acid catalyst, preferably a large pore zeolite catalyst, which is effective to promote alkylation of the aromatic under first conditions effective to maintain a liquid phase comprising the aromatic and effective to cause the propylene to alkylate said aromatic but substantially ineffective to cause the ethylene to alkylate said aromatic, forming propylated aromatic and a second dilute stream comprising ethylene but substantially depleted of propylene, and (b) recovering the propylated aromatic.
