Abstract:
1. A process for catalytic conversion of feedstock comprising at least one alkylatable aromatic compound and an alkylating agent to conversion product which comprises an alkylaromatic compound, said process comprising the step of contacting said feedstock under catalytic conversion conditions including a temperature of from about 0° C. to about 1000° C., a pressure of from about 0.1 atmosphere to about 1000 atmospheres, and a feed weight hourly space velocity (WHSV) of from about 0.01 to 500 hr −1 or a reaction time of from about 1 minute to about 100 hours with a catalyst composition comprising an acidic, porous crystalline material, wherein said catalyst composition is produced by the steps of: (a) providing a first catalyst comprising said acidic, porous crystalline material, said first catalyst having a first proton density; (b) contacting said first catalyst of step (a) with water in liquid form at a contact temperature from about 1° C. to about 99° C., to add protons and generate a second catalyst having a second proton density, wherein the value of said second proton density is greater than said value of said first proton density when said values are measured under the same conditions; and (c) drying said second catalyst of step (b) at a drying temperature of up to about 550° C., to remove at least a portion of said protons from said second catalyst and generate said catalyst composition having a third proton density, wherein the value of said third proton density is between said value of said first proton density and said value of said second proton density when said values are measured under the same conditions, wherein said acidic, porous crystalline material is selected from the group consisting of MCM-22, MCM-49, zeolite beta and mixtures thereof.
