Hydrodenitrification catalyst |
摘要 |
A method for preparing hydrotreating catalysts containing Group VIII and/or Group VIB catalytically active metals on a support, and particularly those containing nickel and molybdenum, are improved in hydrodenitrification (HDN) activity by incorporating zero-valence molybdenum and/or tungsten carbonyls into the catalyst support by mixing a liquid mixture containing metal carbonyl(s); a catalytic amount of dienes, trienes or monoaromatics; and free sulfur; with a dried catalyst support and heating the liquid-solid mixture until metal carbonyl conversion to metal disulfide is substantially complete. The catalyst is then dried followed by calcining in inert gas, before use in a hydrotreating process.
