| abstract | A process of producing an alkylaryomatic by alkylating an aromatic with an alkylating agent, the process comprising: providing at least one reaction zone containing a regenerated H-beta zeolite catalyst and in which the at least one zone of reaction comprises at least one preliminary alkylation reactor and at least one primary alkylation reactor and in which the H-beta zeolite catalyst in the first preliminary alkylation system is regenerated in situ; introducing a feed stream comprising an aromatic and an alkylating agent into the reaction zone; and reacting at least a portion of the aromatic under alkylation conditions to produce an alkyl aromatic; wherein the production of the alkyl aromatic with the regenerated H-beta zeolite catalyst is within 90% of a production rate of an alkyl aromatic with a new H-beta zeolite; wherein the regenerated H-beta zeolite catalyst has a deactivation rate that is not greater than 120% of the deactivation rate of a new H-beta zeolite catalyst in which the feed stream additionally comprises poison poisons. catalyst, which are nitrogen components, having an average of at least 30 ppb in which said regenerated H-beta zeolite catalyst is regenerated by: - the H-beta zeolite catalyst is heated to a first temperature of 370 ° C in a nitrogen-containing gas - the oxygen content is then stepped up from a gas containing 0.2 mol% oxygen until the catalyst regeneration temperature rises to 480 ° C and 540 ° C - the oxygen content is then stepped up to a gas containing 2.0 mol% to maintain the catalyst regeneration temperature at 510 ° C until the outlet stream has an oxygen content of 0.2 mol% - the H-beta zeolite catalyst is heated to a second temperature of 500 ° C; the oxygen content in the outlet stream increases due to a lack of consumption and reaches the content of the injected gas which is 2.0 mol%. |
