Latest Patents

Andrew Sullivan holds a patent for the "Recovery of the transition metal component of catalyst used in heavy." This invention relates to a process for recovering the transition metal component of catalysts utilized in hydroconversion. The process involves catalytically desulfurizing a slurry of a transition metal catalyst and hydrocarbon, resulting in a desulfurized product and a solid residue containing the transition metal. The transition metal can be recovered by coking the residue and dividing the coker residue into two portions, which are combusted. The flue dust from the first combustion zone is conducted to the second combustion zone, where it is treated with ammonia and ammonium carbonate to obtain ammonium molybdate.
