METHOD FOR ALKYLATING ALKYLATION MATERIAL USING ALKYLATION AGENT

摘要

PROBLEM TO BE SOLVED: To provide a method for removing nitrogen compounds from an alkylation substrate such as benzene.

SOLUTION: An adsorbent bed 46 can be used to adsorb basic organic nitrogen compounds and a hot adsorbent bed 72 of acidic molecular sieve can adsorb the weakly basic nitrogen compounds such as nitrites. Water facilitates the adsorption of the weakly basic nitrogen compounds. Running an alkylation substrate stream 68 from a fractionation column 40 of elevated temperature and suitable water concentration to the hot adsorbent bed may be advantageous.
