Abstract: A process for producing terephthalic acid, comprising: passing a feed stream through a catalytic reactor wherein the feed stream comprises p-xylene; contacting the feed stream with a catalyst within the catalytic reactor to produce an oxidation reaction wherein the catalyst comprises, less than or equal to 10% of a metal component wherein the metal component comprises cobalt ions, manganese ions, or a combination comprising at least one of the foregoing, less than or equal to 15% bromide ions, and less than or equal to 2% silver ions; and producing a product stream comprising terephthalic acid, wherein the product stream exits the catalytic reactor.

Abstract: In an embodiment, a process of making a catalyst can comprise contacting a zeolite with an aluminum solution comprising an aluminum compound at a pH of 2 to 6; calcining the zeolite to form the catalyst; wherein the catalyst comprises 0.1 to 5 wt % aluminum based on the total weight of the catalyst excluding any binder or extrusion aide. In an embodiment, a process of aromatizing methane can comprise aromatizing a feed comprising methane in the presence of the catalyst under aromatization conditions.
