摘要： A method of producing a purified mixed xylene comprising: introducing toluene and methanol to an alkylation reactor (32); reacting the toluene and the methanol in the alkylation reactor (32) to form a hydrocarbon stream (22) comprising a first mixed xylene, wherein the alkylation reactor (32) comprises an alkylation catalyst; separating the hydrocarbon stream (22) into a toluene stream (24) and a separated C8+ stream (14); introducing the toluene stream (24) to a transalkylation reactor (38) with a transalkylation catalyst to produce a transalkylated stream (17) comprising a second mixed xylene; adding the transalkylated stream (17) to the hydrocarbon stream (22); and separating a C8 product stream (19) comprising the purified mixed xylene from the separated C8+ stream (14).
