Abstract: A process for producing a supported Fischer-Tropsch catalyst includes treating, in an activation stage (12), a particulate pre-reduction cobalt nitrate-based supported Fischer-Tropsch synthesis catalyst precursor containing reducible cobalt oxides, with hydrogen as a reducing gas in order to reduce the cobalt oxides over a period of time to Co, with ammonia and water being formed, the reduction including a time period when predominantly CoO is reduced to Co. Unreacted hydrogen is withdrawn (20), which thus includes water and treated to lower its dewpoint (14). At least a portion of the withdrawn unreacted hydrogen is returned to the activation stage (12) as recycle hydrogen (26). An ammonia concentration is maintained in the activation stage (12), at least during the time when predominantly CoO is reduced to Co, of less than 250 volume parts per million (‘vppm’).

Abstract: A process is disclosed for regenerating a catalyst used in a process for synthesizing hydrocarbons. The synthesis process involves contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising hydrocarbons. The regeneration process involves contacting a deactivated Fischer-Tropsch catalyst with a regeneration gas under regeneration-promoting conditions that include a pressure lower than the mean Fischer-Tropsch reaction pressure, for a period of time sufficient to reactivate the Fischer-Tropsch catalyst.

Abstract: In a method and apparatus for regenerating a lean NOx adsorber, the NOx adsorber treats exhaust gases created during the combustion of gaseous fuels in general. A bypass line maintains a target regeneration flow of exhaust gas through the NOx adsorber during regeneration regardless of operating demands on the engine. Closed-loop and open-loop control are employed. The closed-loop control employs sensors that determine properties of the exhaust gas during regeneration, and the controller uses those properties to provide an efficient regeneration cycle. A regeneration map is also provided that uses creation of in-cylinder regeneration conditions for the exhaust gas in combination with in-line regeneration conditions for the exhaust gas.
