Patent ID: 7744828

Claim:
An alkylation system comprising: an impurity adsorption vessel comprising: a clay or a resin adsorbent selective for the adsorption of impurities; an alkylation substrate feed inlet; and a purified alkylation substrate feed outlet; a nitrogen adsorption vessel comprising: a denitrogenating adsorbent comprising a molecular sieve selective for the adsorption of a nitrogen compound; an inlet for a purified substrate feed, said inlet in downstream communication with said purified alkylation substrate feed outlet; water, having a concentration between about 20 wppm to about 500 wppm of the purified substrate feed, and a denitrogenated alkylation substrate feed outlet; and at least one aromatic alkylation reactor vessel comprising: an aromatic alkylation catalyst for alkylating an alkylation agent and an aromatic alkylation substrate under alkylation conditions; at least one alkylation reactor inlet in downstream communication with said denitrogenated alkylation substrate feed outlet; and an alkylation reactor outlet.
