摘要： There is provided a process for renewing the activity of supported metal catalysts for the hydrogenation of carbon monoxide to form a mixture of hydrocarbons comprising decreasing the hydrocarbon content of the catalyst, preferably by contact with hydrogen-containing gas at elevated temperatures, impregnating under a non-oxidizing atmosphere with a solution of at least one of an ammonium salt and an alkyl ammonium salt, optionally in combination with up to five moles of ammonia per liter of solution to the point where it has absorbed a volume of solution equal to at least about 10% of its calculated pore volume; oxidizing the catalyst with a gaseous oxidant in the presence of the impregnating solution and activating the catalyst by reduction with hydrogen at elevated temperatures. Optionally, the catalyst is calcined after the oxidation step, and passivated after the activation step.

摘要： There is provided a process for hydrocarbon synthesis wherein a supported metal catalyst for hydrogenating carbon monoxide to form a mixture of hydrocarbons is regenerated by decresing its hydrocarbon content, impregnating under a non-oxidative atmosphere with a solution of at least one member selected from the group consisting of ammonium salts, alkyl ammonium salts and weak organic acids, optionally including ammonia, oxidizing with a gaseous oxidant in the presence of the impregnating solution, activiting the catalyst by reduction with hydrogen at elevated temperatures and reusing the catalyst. The treatement may be carried out in a single reactor, or by carring out up to all steps after catalyst has been withdrawn therefrom and returned to at least one reactor. Up to all steps subsequent to decreasing the hydrocarbon content may be affected in a subsequent reactor, or in specialized apparatus.

摘要： The regeneration of platinum group metal suspension catalysts involves a dissolution step using HCl and an oxidant, such as Cl2 or H2O2, and a precipitating step carried out in the presence of a reducing agent, especially an aldehyde, an HCOOH or a formiate. According to the invention, the content of non-platinum metals which are dragged into the catalyst as a result of the method can be reduced by carrying out the precipitation in the presence of a chelate complexing agent for one or more metals selected from the series of metals of groups 2a, 3a, 4a of the periodic table and of the transition elements without elements of the platinum group.

摘要： This invention relates to a method for regenerating a cyclic olefin hydration catalyst, in which a solid acid catalyst is regenerated after its use in a hydration reaction of a cyclic olefin by mixing a water phase containing the solid acid catalyst and an oil phase containing the cyclic olefin and thereby effecting the reaction, which comprises separating the reaction solution into oil phase and water phase at a temperature of 40°C or more and subsequently subjecting at least a portion of the solid acid catalyst in the separated water phase to a regeneration treatment. According to the method of this invention, a catalyst used in the hydration of a cyclic olefin can be separated and regenerated efficiently, and it is a particularly suitable catalyst regeneration method for a case in which hydration of a cyclic olefin is carried out for a prolonged period of time by repeating regeneration and use of the catalyst again and again.
