| titleOfInvention | Alkylation Methods for Increased Conversion and Reduced Catalyst Use |
| abstract | The present invention relates to catalytic reaction zones in which at least first and second vertically spaced olefins and aromatic compounds in one alkylation unit under alkylation reaction conditions to provide an alkylation product. reaction zones, wherein the second catalytic reaction zone is located above the first catalytic reaction zone; In the above, aromatic compounds from each of at least the first and second catalytic reaction zones are contacted with cooling means for re-condensing at least some of the aromatic compounds vaporized with exothermic heat of the reaction of the alkylation process; And from above, the first and second olefin feed rates at such olefin feed rates are maintained such that the olefin partial pressures at the inlets into at least the first and second catalytic reaction zones are maintained to vary below about 10 percent. A process for preparing alkylated aromatic compounds is introduced into each of the at least first and second catalytic reaction zones through each of the second olefin feed streams. The invention also relates to an apparatus for carrying out the alkylation process of the invention. |
