(599g) Aqueous Phase Reforming of Glycerol for Production of Hydrogen over Non-Noble Metal Nano-Catalysts

During the bio-diesel production process, glycerol is surplus as a by-product. In order to fully utilize oversupply glycerol, a quantity of method has been established to produce value-added chemicals, such as propylene glycol, lactic acid. Because of the increasing environmental issues, a concept of carbon neutral and green hydrogen has been put forward. Therefore, many researchers are devoted to transforming glycerol into green hydrogen through reforming reaction. However, the glycerol reforming reaction is a steam reforming reaction in most cases, and requires the use of a high content of precious metals, which have restricted its large-scale application in industry. In an effort to reduce energy consumption and economic cost, non-noble metal catalysts are developed to catalyze this reaction in aqueous phase. Moreover, we attempt to coupling aqueous phase reforming reaction with the hydrogenation reaction of phthalic acid to 1,2-cyclohexanedicarboxylic acid. The aqueous phase reforming reaction have a lower conversion compared with published paper. Consequently, more efficient hydrogen production catalysts should be exploited.
