    Abstract: The multiple zeolite catalyst is a catalytic composition used to convert alkylaromatic hydrocarbons to BTX, particularly to commercially valuable xylenes. The catalyst is formed by mixing at least two zeolites selected from mordenite, beta zeolite, ZSM-5, ZSM-11, ZSM-12, ZSM-22, ZSM-23, MFI topology zeolite, NES topology zeolite, EU-1, MAPO-36, SAPO-5, SAPO-11, SAPO-34, and SAPO-41, and adding at least one metal component selected from Group VI of the Periodic Table of the Elements. The two zeolites have different physical and chemical characteristics, such as pore size and acidity. An exemplary catalyst includes mordenite, ZSM-5, and 3 wt % molybdenum. The multiple zeolite catalyst may further be used to convert toluene to mixed xylene isomers, particularly with a ZSM-5:mordenite ratio of 2:1 by weight.

    Abstract: The present invention provides a catalyst composition which can decompose an organic nitrogen compound at a relatively low temperature to convert the compound to N2 and render it harmless in the purification of an exhaust gas containing the compound (nitrogen-based exhaust gas); a catalyst containing the catalyst composition; a method for producing the catalyst; and an exhaust gas purification apparatus containing the catalyst.By using a catalyst composition formed by mixing copper oxide particles and zeolite particles, an organic nitrogen compound and/or ammonia can be converted to N2 highly selectively. The catalyst composition of the present invention may further contain a manganese oxide and/or a precious metal.
