摘要： A catalyst composition and a process for hydrodealkylating a C9null 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 C9null aromatic compound with the catalyst composition under a condition sufficient to effect the conversion of a C9null aromatic compound to a C6 to C8 aromatic hydrocarbon.

摘要： Disclosed are a process for producing aromatic hydrocarbon compounds and liquefied petroleum gas (LPG) from a hydrocarbon feedstock having boiling points of 30-250null C. and a catalyst useful therefor. In the presence of said catalyst, aromatic components in the hydrocarbon feedstock are converted to BTX-enriched components of liquid phase through hydrodealkylation and/or transalkylation, and non-aromatic components are converted to LPG-enriched gaseous materials through hydrocracking. The products of liquid phase may be separated as benzene, toluene, xylene, and C9 or higher aromatic compounds, respectively according to their different boiling points, while LPG is separated from the gaseous products, in a distillation tower.
