description | An alkylation-transalkylation process for the production of a monoalkylated aromatic compound is disclosed which maximizes the production of desirable monoalkylaromatic compounds, while limiting transalkylation catalyst deactivation. The process entails the combination of an alkylation reaction zone, a first seperation zone, a second separation zone, and a transalkylation reaction zone wherein the alkylation catalyst and transalkylation catalyst are dissimilar and where the alkylation catalyst is comprised of phosphoric acid material and the transalkylation catalyst is comprised of a crystalline aluminosilicate material. The transalkylation catalyst deactivation is reduced by transalkylating only dialkylated aromatic compounds. Additionally, the transalkylation catalyst is regenerable utilizing a hot liquid hydrocarbon wash. |
