An interest in the on-purpose production of 1,3-butadiene (1,3-BD) has grown, as a consequence decline naphtha cracking for ethene and propene, products that can now be produced economically by thermal dehydrogenation ethane propane contained natural gas. In this study, mechanism kinetics n-butane to 1,3-BD are explored over atomically distributed Pt sites grafted onto dealuminated zeolite BEA ...
Mechanistic insight into the semihydrogenation of 1-butyne and 2-butyne on Cu nanoparticles supported on partially dehydroxylated silica (Cu/SiO2-700) was obtained using parahydrogen. Hydrogenation of 1-butyne over Cu/SiO2-700 yielded 1-butene with ≥97% selectivity. The surface modification of this catalyst with tricyclohexylphosphine (PCy3) increased the selectivity to 1-butene up to nearly 10...
The present study complements our previous studies of the reactions hydrogen atoms with C5 alkene species including 1- and 2-pentene branched isomers (2-methyl-1-butene, 2-methyl-2-butene, 3-methyl-1-butene), by studying C2–C4 alkenes (ethylene, propene, 2-butene, isobutene). aim current work is to develop a hierarchical set rate constants for Ḣ atom addition C2–C5 alkenes, both linear branched...
