摘要： The invention relates to a production method for an oxide capable of efficiently producing an oxide of an organic compound in the presence of raw materials for a Pt/Bi composite catalyst, and to a production method for a Pt/Bi composite catalyst capable of producing a catalyst that exhibits a high activity for dehydrogenation oxidation reaction of an organic compound even in the presence of an organic compound to be a raw material for an oxide. The oxide production method includes subjecting an organic compound having one primary hydroxy group to a dehydrogenative oxidation reaction in the presence of Pt supported by a carrier, a Bi ion source and water, under the condition such that the minimum value of the pH during the reaction is less than 7, thereby obtaining an oxide of the organic compound.

摘要： Oxidative dehydrogenation of paraffins to olefins provides a lower energy route to produce olefins. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, manufacture of glycols, and carboxylic acids and esters. Additionally, oxidative dehydrogenation processes can be integrated with the back end separation process of a conventional steam cracker to increase capacity at reduced cost.

摘要： In some variations, the invention provides a process for producing furfural, 5-hydroxymethylfurfural, and/or levulinic acid from cellulosic biomass, comprising: fractionating the feedstock in the presence of a solvent for lignin, sulfur dioxide, and water, to produce a liquor containing hemicellulose, cellulose-rich solids, and lignin; hydrolyzing the hemicellulose contained in the liquor, to produce hemicellulosic monomers; dehydrating the hemicellulose to convert at least a portion of C5 hemicelluloses to furfural and to convert at least a portion of C6 hemicelluloses to 5-hydroxymethylfurfural; converting at least some of the 5-hydroxymethylfurfural to levulinic acid and formic acid; and recovering at least one of the furfural, the 5-hydroxymethylfurfural, or the levulinic acid. Other embodiments provide a process for dehydrating hemicellulose to convert oligomeric C5 hemicelluloses to furfural and to convert oligomeric C6 hemicelluloses to 5-hydroxymethylfurfural. The furfural may be converted to succinic acid, or to levulinic acid, for example.
