NOVEL MULTIMETALLIC SULFIDE CATALYSTS CONTAINING NOBLE METALS AND HYDRODENITROGENATION PROCESS USING SAME |
摘要 |
The present invention relates to novel catalysts for removing heteroatoms, particularly nitrogen, from hydrocarbonaceous feedstocks. The catalysts are comprised of highly dispersed molybdenum sulfide promoted with a noble metal such that the noble metal is in an oxidation state greater than 0 and coordinated to S. The noble metal is selected from Pt, Pd, Rh, and Ir. It is preferred that the catalysts of be prepared from a precursor composition selected from platinum ethoxyethyl xanthate or platinum dithiocarbamate. Additionally, the catalyst may include a promotor sulfide such as nickel sulfide, cobalt sulfide or iron sulfide, etc. or mixtures thereof.
