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:
A new regeneration method has been developed which can effectively and efficiently remove sulfur from Ni-based steam reforming catalysts. In its simplest form the present invention comprises the steps of oxidizing a catalyst with a dilute O2 stream; decomposing the nickel sulfate under inert gas stream and removing sub-surface sulfur under steam reforming conditions. In some embodiments these steps can all be accomplished and the regenerated catalyst be reintroduced to a steam reforming operation in a matter of eight hours or less.
