The use of biomass-derived compounds as substitutes of pet roleum has received much a t tent ion1)~4). Because of the complex nature of biomass, the conversions of biomass to chemicals usually start with the production of small molecules called platform chemicals by thermal, chemical or biological processing5). Among these platform chemicals, furfural6) and 5hydroxymethylfurfural (HMF)7) are es...

The kinetic relevance and rates of elementary steps involved in C−C bond hydrogenolysis for isobutane, neopentane, and 2,3-dimethylbutane reactants were systematically probed using activation enthalpies and free energies derived from density functional theory. Previous studies showed that C−C cleavage in alkanes occurs via unsaturated species formed in fast quasi-equilibrated C−H activation ste...

published in Aduonce ACS Abstracts, January 1, 1994. 0022-36S4/94/2098-124S%04.S0/0 nation at present. Martini2 and Goodmani3 have suggested that the activity of different crystal planes toward hydrogenolysis is responsible for the observed variations in activity with metal particle size. Single-crystal surface science studies have shown these structure-sensitive reactions to proceed more rapid...
