    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 C8+ stream; 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 C8 product stream comprising the purified mixed xylene from the separated C8+ stream.

    Abstract: In one embodiment, a formed catalyst can comprise: a Ge-ZSM-5 zeolite; a binder comprising silica with 1 to less than 5 wt % non-silica oxides; less than or equal to 0.1 wt % residual carbon; 0.4 to 1.5 wt % platinum; and 4.0 to 4.8 wt % Cs; wherein the weight percentages are based upon a total weight of the catalyst. In one embodiment, a method of making a formed catalyst can comprise: mixing an uncalcined Ge-ZSM-5 zeolite and a binder to form a mixture; forming the mixture into a formed zeolite; calcining the formed zeolite to result in the formed zeolite having less than or equal to 0.1 wt % of residual carbon; ion-exchanging the formed zeolite with cesium; depositing platinum on the formed zeolite; and heating the formed zeolite to result in a final catalyst; wherein the final catalyst comprises 4.0 to 4.8 wt % cesium and 0.4 to 1.5 wt % platinum.
