Hydrotreating catalyst composition and processes therefor and therewith

摘要

A nitrided calcined modified zeolite composition having incorporated therein a molybdenum promoter and a co-promoter. A carburized nitrided calcined modified zeolite composition having incorporated therein a molybdenum promoter and a co-promoter. Producing the composition by incorporating a molybdenum promoter compound and a co-promoter compound into the zeolite followed by thermal treatment of the resulting zeolite with a nitriding agent and, optionally, further thermally treating the resulting zeolite with a hydrocarbon, preferably in the presence of hydrogen. A hydrotreating process that contacts a hydrocarbon-containing fluid with the nitrided, optionally carburized, calcined modified zeolite composition under a condition sufficient to effect the reduction of sulfur content in the hydrocarbon-containing fluid.
