    摘要: The present invention relates to a method for removing a sulfur containing catalyst poison from a feedstock. Benefits from removing catalyst poisoning sulfur compounds in a feedstock include upgrading the quality of the various petroleum fractions and prolonging the life of the catalyst. A preferred embodiment of the present invention includes adding a sacrificial metal to a Fischer-Tropsch reactor. The role of the sacrificial metal is adsorption of the sulfur-containing species that may deactivate or poison the catalyst.

    摘要: The invention provides processes for selectively oxidizing carbon monoxide from an input gas stream that contains carbon monoxide, oxygen and hydrogen. The process includes the step of contacting the input gas stream with a preferential oxidation catalyst. The preferential oxidation catalysts are copper-based catalysts containing low concentrations of platinum group metals. In some embodiments, the processes of the invention are conducted using preferential oxidation catalysts having an oxide support on which is dispersed copper or an oxide thereof, a platinum group metal and a reducible metal oxide. In other embodiments, the processes of the invention are conducted with a preferential oxidation catalysts having a cerium oxide support on which is dispersed copper or an oxide thereof and a platinum group metal.

    摘要: Catalysts for oxidative dehydrogenation of alkane to one or more olefins, exemplified by ethane to ethylene, are disclosed. The catalyst comprises a mixture of metal oxides having as an important component nickel oxide (NiO) and gives high conversion and selectivity. For example, the catalyst can be used to make ethylene by contacting it with a gas mixture containing ethane and oxygen. The gas mixture may optionally contain ethylene, an inert diluent such as nitrogen, or both ethylene and an inert diluent.
