摘要： A method for recovering metals from a spent dispersed catalyst originating from a Group VIB metal sulfide catalyst containing at least a Group VB and Group VIII metal for hydrocarbon oil hydroprocessing is disclosed. In one embodiment, the method comprises the steps of: contacting the spent dispersed catalyst with a leaching solution containing ammonia and air to dissolve the group VIB metal and the Group VIII metal into the leaching solution at sufficient temperature and pressure; forming a slurry containing at least a group VIB metal complex and at least a group VIII metal complex, ammonium sulfate and solid residue containing at least a Group VB metal complex and coke; separating and removing the solid residue containing ammonium metavanadate and coke from the pressure leach solution (PLS); precipitating from the PLS at least a portion of the Group VIB metal and at least a portion of the Group VIII metal by controlling the pH at a pre-selected pH to selectively precipitate as metal complexes the Group VIB and Group VIII metals.

摘要： A process for hydroprocessing heavy oil feedstock is disclosed. The process operates in once-through mode, employing a plurality of contacting zones and at least a separation zone to convert at least a portion of the heavy oil feedstock to lower boiling hydrocarbons, forming upgraded products. The contacting zones operate under hydrocracking conditions, employing a slurry catalyst for upgrading the heavy oil feedstock. At least an additive material selected from inhibitor additives, anti-foam agents, stabilizers, metal scavengers, metal contaminant removers, metal passivators, and sacrificial materials, in an amount of less than 1 wt. % of the heavy oil feedstock, is added to at least one of the contacting zones. In one embodiment, the additive material is an anti-foam agent. In another embodiment, the additive material is a sacrificial material for trapping heavy metals in the heavy oil feed and/or deposited coke, thus prolonging the life of the slurry catalyst.

摘要： A method is disclosed for separating and recovering base metals from a used hydroprocessing catalyst originating from Group VIB and Group VIII metals and containing at least a Group VB metal. In one embodiment, the used catalyst is contacted with an ammonia leaching solution to dissolve and separate the Group VIB and VIII metals from the Group VB metal complex and coke associated with the used catalyst. The resulting Group VIB and VIII metal containing solution is processed through at least two additional precipitation and liquid/solid separation steps to produce, in separate processing streams, a Group VIB metal product solution (such as ammonium molybdate) and a Group VIII metal product solution (such as nickel sulfate). Additionally, two separate filtrate streams are generated from liquid-solid separation steps, which filtrate streams are combined and subjected to hydrolysis and oxidation (oxydrolysis) to generate a purified ammonium sulfate solution for further processing, such as for fertilizer.
