摘要： The present invention provides methods to maintain selectivity to ethanol from syngas during mixed-alcohol synthesis when methanol is being recycled. In some variations, syngas is fed to an alcohol-synthesis reactor that contains a sulfided metal catalyst, and methanol is separated from ethanol to form a methanol recycle stream that contains sulfur-containing compounds. Recycling the methanol stream back to the alcohol-synthesis reactor allows for adding sulfur to, or reducing sulfur loss from, the sulfided metal catalyst. Optionally, additional sulfur compounds may be introduced to maintain sulfur levels in sulfided metal catalysts. Preferred sulfiding agents, concentrations, and recycle strategies are disclosed herein.

摘要： The invention provides methods and apparatus for selectively producing ethanol from syngas. As disclosed herein, syngas derived from cellulosic biomass (or other sources) can be catalytically converted into methanol, which in turn can be catalytically converted into acetic acid or acetates. Finally, the acetic acid or acetates can be reduced to ethanol according to several variations. In some embodiments, yields of ethanol from biomass can exceed 100 gallons per dry ton of biomass.

摘要： Improved methods of introducing promoters to catalysts are described. The present invention provides a convenient method of uniformly distributing a catalyst promoter, to provide for intimate contact between the promoter and the active catalyst sites. This intimate contact can enhance the activity and/or product selectivity of the promoted catalyst. In some embodiments, the method includes reacting an alkali metal with an alcohol in a non-aqueous medium, contacting the resulting solution with a starting catalyst, and depositing the alkali metal onto the starting catalyst to form an alkali-promoted catalyst.
