摘要： Catalyst beds in refinery reactors require periodic change out due to build-up of contamination and loss of activity. The instant invention mists a liquid chemical solvent in nitrogen carrier gas to solubilize oils and heavy hydrocarbons and to further desorb light hydrocarbons and remove hydrogen sulfide (H2S), to effect decontamination. This process can be advantageously combined with nitrogen cool-down processes in preparation for catalyst unloading.

摘要： Methods and apparatus for providing the heat required to maintain the desired temperature for catalyst regeneration. The catalyst is heated by contacting a reactant gas mixture with the catalyst in order to initiate an exothermic reaction and, once the desired temperature is achieved, exposing the catalyst to a regenerating gas. The temperature may also be maintained by heating the reactant gas mixture prior to contacting the catalyst and/or adding a liquid, which may be heated, to the catalyst. For heating a Fischer-Tropsch catalyst for regeneration, the reactant gas preferably contains less than 12 mole percent carbon monoxide and more preferably contains between 1 and 4 mole percent carbon monoxide.

摘要： Methods and systems are provided for maintaining efficiency of a catalyst that is positioned in an exhaust system downstream of an internal combustion engine. In one example, the catalyst may be heated via supplying fuel to a cylinder that does not combust the fuel. The fuel may be oxidized at the catalyst via excess oxygen in the exhaust system.

摘要： Some embodiments of the present invention relate to processes to recover rhodium from a hydroformylation process. In some embodiments, the process to recover rhodium from the hydroformylation process comprises (a) treating a catalyst-containing stream from the hydroformylation process with 2.5 to 20 weight percent, based on the total weight of the stream, of a water-soluble organic amine of the following structure: wherein R32, R33, and R34 are each independently alkyls and ethoxylates, and wherein no more than one of R32, R33, and R34 is alkyl; (b) heating the resulting solution in the presence of syngas to a temperature of at least 65° C. to generate a rhodium-rich phase and a supernatant; and (c) removing the supernatant to recover the rhodium-rich phase.
