    Abstract: PROBLEM TO BE SOLVED: To provide a catalyst for hydrogenolysis of a polyhydric alcohol with a long lifetime which can be reused and can produce a hydrogenolysis product from a polyhydric alcohol in a high yield even without using a liquid acid catalyst and to provide a method for producing 1,3-propanediol from glycerol using the catalyst.SOLUTION: A catalyst for hydrogenolysis of the present invention is obtained by carrying a platinum component and a tungsten component on boehmite [AlO(OH)] as a carrier. The platinum component and the tungsten component [the former: the latter (weight ratio)] are preferably contained in the ratio of 1:0.05 to 1:50. The catalyst for hydrogenolysis is preferably obtained by carrying a platinum component and a tungsten component on boehmite [AlO(OH)] as a carrier, followed by baking at 200 to 1000°C for 1 to 5 hours.

    Abstract: A process for the production of propylene glycol by reaction of a feed material comprises glycerol in the presence of hydrogen which comprising the steps of: (a) supplying a stream comprising the feed material to a first vaporisation zone and contacting said feed with cycle gas comprising hydrogen such that at least a portion of the feed is vaporised by and into the cycle gas; (b) supplying at least a portion of the cycle gas and the vaporised feed material to a first reaction zone comprising catalyst and operating under reaction conditions to allow hydrogenation and dehydration to occur such that a major part of the glycerol is converted; (c) recovering from the first reaction zone an intermediate product stream comprising cycle gas, minor amounts of unconverted glycerol, and desired product(s); (d) supplying the intermediate product stream from the preceding reaction zone to a final vaporisation zone and contacting it with additional feed material such that an amount of glycerol, approximately equivalent to that vaporised in the preceding vaporisation zone, is vaporised by and into the intermediate product stream; (e) supplying the stream from step (d) to a final reaction zone comprising catalyst and operating under reaction conditions to allow hydrogenation and dehydration to occur such that a major part of the glycerol is converted; and (f) recovering from the final reaction zone a final product stream comprising cycle gas, minor amounts of unconverted feed glycerol and the desired product(s).
