    • A method is disclosed for preparing a supported hydrogenation metal catalyst containing one each of Mo or W and of Co and/or Ni incorporated into a suitable support. An aqueous impregnating solution containing the desired quantity of catalytically active metals and having a pH in the range of about 0.7-2.7 is prepared containing (1) at least one each of a soluble compound of molybdenum or tungsten and a compound of cobalt and/or nickel; (2) a solubilizing amount of about 0.2-1.0 mole of phosphorous per mole Mo or W; and (3) about 2-6% w basis support, of a suitable soluble amine compound, such as amine alcohols, polyamines and amine acids. A suitable support, e.g., alumina, silica or silica-alumina, is then impregnated with the metals-containing solution. After impregnation the support is dried and calcined. This preparation method significantly increases the hydrodenitrification activity of the resulting catalyst in a hydrocarbon hydroconversion process.
    • 公开了一种制备负载氢化金属催化剂的方法,该催化剂含有Mo或W中的每一种,Co和/或Ni掺入合适的载体中。 制备含有所需量的催化活性金属并且pH在约0.7-2.7范围内的含水浸渍溶液,其含有(1)至少一种钼或钨的可溶性化合物和钴和/或 镍; (2)每摩尔Mo或W的增溶量为约0.2-1.0摩尔的磷; 和(3)约2-6%w的载体,适合的可溶性胺化合物,例如胺醇,多胺和胺酸。 然后用含金属的溶液浸渍合适的载体,例如氧化铝,二氧化硅或二氧化硅 - 氧化铝。 浸渍后,将载体干燥并煅烧。 该制备方法显着提高了所得催化剂在烃加氢转化方法中的加氢脱氮活性。
