摘要： The present invention provides a method for preparing 1,5-pentanediol via hydrogenolysis of tetrahydrofurfuryl alcohol. The catalyst used in the method is prepared by supporting a noble metal and a promoter on an organic polymer supporter or an inorganic hybrid material supporter, wherein the supporter is functionalized by a nitrogen-containing ligand. When the catalyst is used in the hydrogenolysis of tetrahydrofurfuryl alcohol to prepare 1,5-pentanediol, a good reaction activity and a high selectivity can be achieved. The promoter and the nitrogen-containing ligand in the supporter are bound to the catalyst through coordination, thereby the loss of the promoter is significantly decreased, and the catalyst has a particularly high stability. The lifetime investigation of the catalyst, which has been reused many times or used continuously for a long term, suggests that the catalyst has no obvious change in performance, thus reducing the overall process production cost.

摘要： Disclosed is a supported catalyst for the preparation of vinyl acetate monomer (VAM), a process for preparing a catalyst comprising an extruded alumina support, and a catalytic process for the manufacturing vinyl acetate using the supported catalyst. Specifically, it is shown that for activated palladium-gold VAM catalysts prepared using extruded alumina supports, enhanced performance is demonstrated with increased pore volume of the support, and the gas hourly space velocity (GHSV, hr−1), which was found to significantly increase the space time yield as GHSV increased as compared to the non-extruded alumina supported catalysts.

The particles are dispersed throughout the eutectic composition when the eutectic composition is solid, and the particles are dispersed or suspended throughout the eutectic composition when the eutectic composition is in liquid form. At least one metal of the eutectic may comprises lead and a metal in the metal catalyst is a different metal then the metals in the eutectic. The eutectic may be in a liquid state and the metal catalyst particles may be in an equilibrium state within the eutectic.
