    摘要: A combined filtering process for recycling a precious metal from a Fischer-Tropsch synthetic product with the steps of: 1) after the product of a Fischer-Tropsch synthesis reaction is filtered by an inner filter, the product is introduced into a first filter buffer tank from an outlet on the upper part of a Fischer-Tropsch synthesis reactor, where a gas-phase product or a partially liquid-phase product filtered from the product by the first filter buffer tank is discharged from the top part, and where liquid-phase and solid-phase products discharged from the bottom part of the first filter buffer tank are introduced into a refining filter for product refinement; 2) the liquid-phase product that is mainly a catalyst slurry is introduced from the bottom part of the Fischer-Tropsch reactor into a dynamic filter for filtering, where the filtered liquid-phase product containing small particles of a spent catalyst and precious metal ions dissolved in the product is separated from the bottom part of the dynamic filter, introduced into a second filter buffer tank, and introduced from the bottom part of the second filter buffer tank into the refining filter for refinement; and, 3) a white clay cake is first formed on a filter plate in the refining filter, then, with respect to the product introduced into the refining filter, when the white clay cake is formed, a product refinement process is utilized for refinement processing of the product.

    摘要: The invention relates to a process for recovering Group VIB metals from a catalyst, in particular a spent bulk catalyst, comprising one or more Group VIB metals and one or more Group VIII metals. Further, the invention relates to a solid Group VIB metal compound obtainable by the process according to the invention having the general formula H 2 XO 4 , wherein X = W 1-y Mo y , wherein y is between 0 and 1 and to its use in a process for the manufacture of a fresh catalyst. The process comprises the steps of: a) oxidizing the one or more Group VIB metals to one or more Group VIB metal oxides; separating the one or more Group VIB metal oxides from the one or more Group VIII metals; dissolving the one or more Group VIB metal oxides in water to produce an aqueous solution of one or more Group VIB metal oxides; d) precipitating the one or more Group VIB metal oxides from the aqueous solution by adding alkaline earth metal (Group IIa) ions to the aqueous solution; e) optionally filtering and washing the precipitate; and f) transforming the precipitate by adding an acid to form a solid metal compound comprising one or more Group VIB metals.

    摘要: This invention relates to a process for the removal of catalyst particles from a hydrocarbon stream (14) derived from the reaction of synthesis gas (12) with a particulate Fischer Tropsch catalyst in a Fischer Tropsch reactor (10). The process includes a primary separation step (16) which makes use of a filter, wherein the filter has a pore size which is 70% to 95 of the average size of the particles of the Fischer Tropsch catalyst, thereby forming a primary filtered hydrocarbon stream (18) containing fine catalyst particles. The benefit of this selection of filter pore size is that it mitigates fines build-up on the filter of the primary separator. The primary filtered hydrocarbon stream (18) is then passed to a secondary separation step in a cross-flow filtration unit (20) which removes fine catalyst particles from the primary filtered hydrocarbon stream to provide a retenate (24) containing the catalyst fines, and permeate (22) containing a hydrocarbon product.
