Publication number: 20110224468Abstract: In a process for alkylation of an alkylatable aromatic compound to produce a monoalkylated aromatic compound, a first feed stream comprising fresh alkylatable aromatic compound is passed to a first reaction zone which comprises a transalkylation catalyst and which also receives a second feed stream comprising polyalkylated aromatic compounds. The first and second feed streams are contacted with the transalkylation catalyst in the first reaction zone under conditions to transalkylate the polyalkylated aromatic compounds with the alkylatable aromatic compound to produce the desired monoalkylated aromatic compound. A first effluent stream comprising unreacted alkylatable aromatic compound and the monoalkylated aromatic compound is removed from the first reaction zone and passed to a fractionation system to separate the first effluent stream into a first light fraction comprising the unreacted alkylatable aromatic compound and a first heavy fraction comprising the monoalkylated aromatic compound.Type: ApplicationFiled: September 24, 2009Publication date: September 15, 2011Inventors: Matthew J.

Publication number: 20110224469Abstract: Disclosed is a process for the production of alkylated aromatics by contacting a feed stream comprising an alkylatable aromatic, an alkylating agent and trace amounts of water and impurities in the presence of first and second alkylation catalysts wherein the water and impurities are removed in order to improve the cycle length of such alkylation catalysts. Water and a portion of impurities are removed in a dehydration zone. A first alkylation zone having a first alkylation catalyst which, in some embodiments is a large pore molecular sieve, acts to remove a larger portion of impurities, such as nitrogenous and other species, and to alkylate a smaller portion of the alkylatable aromatic compound. A second alkylation zone, which in some embodiments is a medium pore molecular sieve, acts to remove a smaller portion of impurities, and to alkylate a larger portion of the alkylatable aromatic compound.Type: ApplicationFiled: March 10, 2010Publication date: September 15, 2011Inventors: Matthew J.
