PROCESS FOR PRODUCTION OF AROMATIC HYDROCARBON

摘要

A process for producing an aromatic hydrocarbon using a lower hydrocarbon as the starting material, the process comprising heating the hydrocarbon in the presence of a catalyst composed of metallosilicate support modified with a silicon compound, a sodium compound or a calcium compound on which a molybdenum compound or a rhenium compound is supported, the silicon compound being a silane compound having a basic group selected from amino, alkylamino and pyridyl groups and an organic group having a size equal to or greater than the pore size of the metallosilicate and selected from trialkoxy and triphenyl groups and, the sodium compound or the calcium compound being a compound having an organic group which has a size equal to or greater than the pore size of the metallosilicate and is selected from crown ether, hexafluoropentadione and acetylacetonate, the catalyst being prepared by impregnating the metallosilicate support with the silane, sodium or calcium compound and then treating the resulting product with heating in an oxygen-containing atmosphere to cause the modification of the metallosilicate support with an oxide of the silane, sodium or calcium compound.
