摘要:The present invention relates to enhancement of the cycle life of a zinc chromium based catalyst used in the synthesis of 2-methylpyrazine by increasing the reaction temperature step-wise, starting from a low temperature, while monitoring the levels of total conversion and selectivity towards pyrazine. The catalyst can be regenerated after each cycle of use without substantial loss of activity.

摘要:A ferrihydrite catalyst composition can comprise a ferrihydrite of a structural promoter metal, a chemical promoter metal and potassium to form an amorphous nanoparticulate. The ferrihydrite catalyst can be formed by dissolving an iron salt, a structural promoter metal salt and a chemical promoter metal salt in water to form an aqueous iron solution. A ferrihydrite solid can be precipitated from the aqueous iron solution by addition of a precipitating agent under conditions such that the ferrihydrite solid is a nanoparticulate. A potassium can be incorporated into the ferrihydrite solid to form a ferrihydrite catalyst precursor. The ferrihydrite catalyst precursor can be calcined to form the ferrihydrite catalyst. A synthesis gas can be readily converted to a fuel product by contacting the ferrihydrite catalyst with the synthesis gas under reaction conditions sufficient to form a fuel product mixture.

摘要:Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.

摘要:A method of synthesizing metal nanoparticles is provided. The method includes submerging an electrically conductive substrate in a polysaccharide solution containing a predetermined concentration of a metal salt; applying an electric potential between the electrically conductive substrate and the polysaccharide solution for a predetermined period of time to form a polysaccharide layer containing metal nanoparticles on the electrically conductive substrate; re-dissolving the polysaccharide layer in a solvent to form a solution including the polysaccharide and the metal nanoparticles; and separating the metal nanoparticles from the polysaccharide.
