A catalyst composition and a process for hydrodealkylating a C9+ aromatic compound such as, for example, 1,2,4-trimethylbenzene to a C6 to C8 aromatic hydrocarbon such as a xylene are disclosed. The composition comprises an alumina, a metal oxide, a phosphorus oxide and optionally, an acid site modifier selected from the group consisting of silicon oxides, sulfur oxides, boron oxides, magnesium oxides, tin oxides, titanium oxides, zirconium oxides, molybdenum oxides, germanium oxides, indium oxides, lanthanum oxides, cesium oxides, and combinations of any two or more thereof. The process comprises contacting a fluid which comprises a C9+ aromatic compound with the catalyst composition under a condition sufficient to effect the conversion of a C9+ aromatic compound to a C6 to C8 aromatic hydrocarbon.
A process comprising contacting a fluid which comprises a C9+ aromatic compound with a catalyst composition under a condition sufficient to effect the conversion of a C9+ aromatic compound to a C6 to C8 aromatic hydrocarbon wherein said catalyst composition is a catalyst composition comprising a metal oxide-promoted alumina and phosphorus oxide, wherein the metal of said metal oxide is molybdenum.
A process comprising contacting a fluid which comprises a C9+ aromatic compound with a catalyst composition under a condition sufficient to effect the conversion of a C9+ aromatic compound to a C6 to C8 aromatic hydrocarbon wherein said catalyst composition is a catalyst composition consisting essentially of an alumina, a metal oxide, a silicon oxide, and a phosphorus oxide wherein
A process comprising contacting a fluid which comprises a C9+ aromatic compound with a catalyst composition under a condition sufficient to effect the conversion of a C9+ aromatic compound to a C6 to C8 aromatic hydrocarbon wherein said catalyst composition is a catalyst composition made by a process comprising the steps of
