Abstract
A method of producing a purified mixed xylene comprising: introducing toluene and methanol to an alkylation reactor (); reacting the toluene and the methanol in the alkylation reactor () to form a hydrocarbon stream () comprising a first mixed xylene, wherein the alkylation reactor () comprises an alkylation catalyst; separating the hydrocarbon stream () into a toluene stream () and a separated Cstream (); introducing the toluene stream () to a transalkylation reactor () with a transalkylation catalyst to produce a transalkylated stream () comprising a second mixed xylene; adding the transalkylated stream () to the hydrocarbon stream (); and separating a Cproduct stream () comprising the purified mixed xylene from the separated Cstream ().
