    摘要: A process for the preparation of a catalyst useful for conducting carbon monoxide hydrogenation reactions, especially Fischer-Tropsch reactions. The steps of the process begin with the activation, or reactivation, of a deactivated catalyst, or with the preparation and activation of a fresh catalyst. In accordance with the latter, the steps of the process comprise, first contacting, in one or more steps, a powder or preformed, particulate refractory inorganic support with a liquid, or solution in which there is dispersed or dissolved a compound, or salt of a catalytically active metal, or metals, to impregnate and deposit the metal, or metals, upon the support, or powder. The metal, or metals, impregnated support is calcined following each impregnation step to form oxides of the deposited metal, or metals. The calcined catalyst precursor is then treated with a solution of a chelating compound, preferably a poly- or multidentate chelating compound, sufficient to complex with, extract and remove a portion of the oxides of the metal, or metals. The catalyst is activated by reduction; suitably by contact with hydrogen. In the activation, or reactivation of a deactivated catalyst, the catalyst is first treated with the chelating compound to extract a portion of the oxides of the metal, or metals, and the catalyst is then reduced. In either event, the activated or reactivated catalyst has high activity, or high C5+ selectivity, or both high activity and C5+ selectivity in conducting carbon monoxide hydrogenation reactions. The productivity of the process is increased.

    摘要: A particulate, precalcined low silica content zirconia, especially one stabilizer with yttria, is useful as a catalyst support or as a heat transfer solids component for conducting chemical reactions at high temperature, in oxidizing, reducing or hydrothermal conditions, especially in syn gas operations. An admixture of precalcined particulate low silica content zirconia, particularly a low silica content yttria-stabilized zirconia, is employed in a preferred embodiment as a heat transfer solid, in concentrations ranging generally from about 10 wt. % to about 99.9 wt. % with a particulate catalyst notably a nickel-on-alumina catalyst, in concentration ranging generally from about 0. 1 wt. % to about 90 wt. %. Such an admixture provides a particularly useful catalytic contact mass in high temperature oxidizing, reducing and hydrothermal environments, notably in conducting synthesis gas generation operations. This type of bed promotes continuous, highly efficient heat and mass transfer within the reacting gas phase. The presence of the heat transfer solid as a bed component maintains excellent bed fluidization characteristics, suppressing the normal tendency of the catalyst to sinter or agglomerate; tendencies which promote defluidization of the bed. Moreover, the heat transfer particles of the bed are highly attrition resistant, and are chemically compatible with the catalyst particles of the admixture.

    摘要: A process utilizing a particulate catalyst, or particulate catalyst admixed with particulate heat transfer solids for conducting high temperature fluidized bed syn gas operations. Hydrogen and carbon monoxide are produced from a low molecular weight hydrocarbon by contact thereof, at high temperature in the presence of oxygen, or steam and oxygen, with a fluidized bed comprising said particulate solids. In one of its forms, barium hexaluminate is employed as a heat transfer solid, in concentrations ranging generally from about 10 wt. % to about 99.9 wt. %, in admixture with a particulate catalyst containing a metal, or metals, component catalytic for the production of hydrogen and carbon monoxide from low molecular weight hydrocarbons contacted with a fluidized bed of the catalyst at high temperature hydrothermal conditions. The catalyst, suitably one having a barium hexaluminate carrier component, is employed in concentration ranging generally from about 0.1 wt. % to about 90 wt. %. Such an admixture provides a particularly useful catalytic contact mass for conducting fluidized bed synthesis gas generation operations. This type of bed promotes continuous, highly efficient heat and mass transfer within the reacting gas phase. The presence of the catalyst having a barium hexaluminate carrier component, or barium hexaluminate heat transfer solid as a bed component maintains excellent bed fluidization characteristics, suppressing the normal tendency of the catalyst to sinter or agglomerate; tendencies which promote defluidization of the bed. Moreover, the heat transfer particles of the bed are highly attrition resistant, and are chemically compatible with the catalyst particles of the admixture.
