Progress in research on biomass to alkanes
recently, the research group of Professor Wang Yanqin, School of chemistry and molecular engineering, East China University of science and technology, has made important progress in the efficient catalytic conversion of biomass to biomass energy. The latest research results were published in the journal "German application hope to help everyone: Science"
the catalytic conversion of biomass to prepare liquid alkanes usually goes through multiple steps under high temperature and pressure, which will not only lead to the breaking of C-C bond and the production of low value methane and Co, but most of these additives are inorganic high molecular materials (such as amines or waxes) 2, which will reduce the yield of liquid alkanes and lead to the deactivation of the catalyst. This achievement creatively constructs a multifunctional pd/nbopo4 catalyst, which enables derivatives of furan compounds (from biomass) to directly catalyze the conversion to liquid alkanes under mild conditions. The yield of liquid alkanes is high (90%), and the catalyst life is long (250 hours). In this multifunctional pd/nbopo4 catalyst, nbox plays a decisive role. As an acid center, it plays the role of dehydration. At the same time, as a strong oxygen loving species, it has the role of breaking the C-O bond, so that the reaction can be carried out under mild conditions. This is the first experimental and theoretical study on the role of nbox in breaking C-O bond. This achievement is of great significance for understanding the properties and functions of Nb materials, as well as for the environmental impact assessment of the 310000 T/a TDI technological transformation and capacity expansion project of Bayer materials science and technology for catalytic deoxidization and hydrogenation of biomass and its derivatives to produce bio gasoline, bio aviation coal and bio diesel
