摘要： The disclosure relates to a process for enriching a synthesis gas in hydrogen by contacting said synthesis gas with a water gas shift catalyst, the synthesis gas being a CO-rich synthesis gas including at least 15 vol % CO and at least 1 ppmv sulfur, and the water gas shift catalyst including Zn, Al, optionally Cu, and an alkali metal or alkali metal compound; the water gas shift catalyst is free of chromium (Cr) and iron (Fe), and has a pore volume, as determined by mercury intrusion, of 240 ml/kg or higher.

摘要： The invention comprises a method of operating a water gas shift reactor in a transient state such as during reactor start-up, the method comprising: providing a water gas shift catalyst comprising an alkali metal or alkali metal compound; heating the water gas shift catalyst up to the reaction temperature of the water gas shift reaction under steam condensing conditions, by applying steam as a heat transfer medium for the water gas shift catalyst, and where the water gas shift catalyst has a total pore volume larger than the volume of liquid water that forms during the heating.

摘要： Process for the catalytic hydrogenation of organic carbonyl compounds containing at least one functional group belonging to the group of aldehydes, ketones, esters and carboxylic acids, whereby said at least one functional group is converted to an alcohol by contacting said carbonyl compound with hydrogen and a hydrogenation catalyst at elevated temperature and pressure as well as a catalyst therefore and a process for producing said catalyst.

摘要： The present disclosure relates to an improved water gas shift catalyst, in particular an improved high temperature shift catalyst and process using the catalyst. The water gas shift catalyst includes Zn, Al, optionally Cu, and an alkali metal or alkali metal compound, wherein the content of alkali metal, preferably K, is in the range 1-6 wt %, such as 1-5 wt % or 2.5-5 wt % based on the weight of oxidized catalyst, and wherein the water gas shift catalyst has a pore volume, as determined by mercury intrusion, of 240 ml/kg or higher, such as 250 ml/kg or higher. A process for enriching a synthesis gas in hydrogen by contacting the synthesis gas in a water gas shift reactor with the water gas shift catalyst.
