摘要:
Methods for producing alcohols from CO or CO2 and H2 utilizing a palladium-zinc on alumina catalyst are described. Methods of synthesizing alcohols over various catalysts in microchannels are also described. Ethanol, higher alcohols, and other C2+ oxygenates can produced utilizing Rh—Mn or a Fisher-Tropsch catalyst.

摘要:
The disclosed invention relates to a process for converting a reactant composition comprising H2 and CO to a product comprising at least one aliphatic hydrocarbon having at least about 5 carbon atoms, the process comprising: flowing the reactant composition through a microchannel reactor in contact with a Fischer-Tropsch catalyst to convert the reactant composition to the product, the microchannel reactor comprising a plurality of process microchannels containing the catalyst; transferring heat from the process microchannels to a heat exchanger; and removing the product from the microchannel reactor; the process producing at least about 0.5 gram of aliphatic hydrocarbon having at least about 5 carbon atoms per gram of catalyst per hour; the selectivity to methane in the product being less than about 25%. The disclosed invention also relates to a supported catalyst comprising Co, and a microchannel reactor comprising at least one process microchannel and at least one adjacent heat exchange zone.
摘要:
Catalysts containing 30 weight percent or more platinum have surprisingly been discovered to possess superior stability and activity for catalyzing combustion reactions. The addition of rhenium improves catalyst performance in fuel lean conditions but has undesirable effects in fuel rich conditions. The invention provides integrated combustion microreactors, chemical systems utilizing these integrated combustion microreactors, methods of combustion, and methods of providing heat to endothermic reactions in integrated combustion microreactors.
