摘要： A process for the recovery of a spent molybdenum catalyst from a hydroprocess for the upgrading of a nickel and vanadium containing hydrocarbonaceous mineral oil. The nickel and vanadium contaminated molybdenum catalyst is oxidized to convert the metals to oxides. Aqueous ammonia is added to preferentially dissolve molybdenum from nickel and vanadium. An amount of ammonia is used in excess of the amount required to produce an active catalyst for recycle and the excess ammonia is removed prior to recycle of the catalyst. The selectively of the separation of molybdenum from nickel and vanadium is improved by adding a reducing agent before or during the ammonia dissolving step. Hydrazine is a suitable reducing agent. The recovered molybdenum is sulfided and recycled.

摘要： A method for dispersing finely divided catalyst precursors onto the surface of coal or other particulate material includes the steps of forming a wet paste mixture of the particulate material and a liquid solution containing a dissolved transition metal salt, for instance a solution of ferric nitrate. The wet paste mixture is in a state of incipient wetness with all of this solution adsorbed onto the surfaces of the particulate material without the presence of free moisture. On adding a precipitating agent such as ammonia, a catalyst precursor such as hydrated iron oxide is deposited on the surfaces of the coal. The catalyst is activated by converting it to the sulfide form for the hydrogenation or direct liquefaction of the coal.
摘要翻译：将细分散的催化剂前体分散到煤或其它颗粒材料的表面上的方法包括形成颗粒材料和含有溶解的过渡金属盐（例如硝酸铁溶液）的液体溶液的湿糊混合物的步骤。湿糊状混合物处于初始湿润状态，所有这些溶液都吸附在颗粒材料的表面上，而不存在游离水分。在加入诸如氨的沉淀剂之后，在煤的表面上沉积诸如水合氧化铁的催化剂前体。催化剂通过将其转化为硫化物形式来活化，用于氢化或直接液化煤。
