摘要： Provided is a method for preparing a diol. In the method, a saccharide and hydrogen as raw materials are contacted with a catalyst in water to prepare the diol. The employed catalyst is a composite catalyst comprised of a main catalyst and a cocatalyst, wherein the main catalyst is a water-insoluble acid-resistant alloy; and the cocatalyst is a soluble tungstate and/or soluble tungsten compound. The method uses an acid-resistant, inexpensive and stable alloy needless of a support as a main catalyst, and can guarantee a high yield of the diol in the case where the production cost is relatively low.

摘要： Disclosed is an acid-resisting alloy catalyst comprising nickel, one or more rare earth elements, stannum and aluminum. The acid-resistant alloy catalyst is low-cost and stable, and does not need a carrier, and can be stably used in continuous industrial production, thus achieving a low production cost.
