Abstract. The effects were studied of high water concentrations on the kinetics of alcohol dehydration, as encountered in aqueous-phase processing of biomass-derived oxygenated hydrocarbons. These studies were carried out for dehydration of an aqueous solution of 10 wt% 2-butanol at 513 K, and at a total pressure of 52 bar to maintain the water in the liquid state. Under these high pressure…
Abstract. Zr-containing CuO/ZnO catalysts are examined for their use in the reaction of methanol with water to produce hydrogen. Catalyst samples with varying compositions were prepared by means of a coprecipitation method, and the effect of different pretreatment conditions was examined. Activity testing shows that the catalysts do not require prereduction to obtain good activity for the stea…
