Title: Cobalt Oxide on N-Doped Carbon for 1-Butene Oligomerization to Produce Linear Octenes

Abstract

Cobalt oxide supported on N-doped carbon catalysts were investigated for 1-butene oligomerization. The materials were synthesized by treating activated carbon with nitric acid and subsequently with NH3 at 200, 400, 600, and 800 °C, followed by impregnation with cobalt. The 1-butene oligomerization selectivity increased with ammonia treatment temperature of the carbon support. The oligomerization selectivity of cobalt oxide on N-doped carbon synthesized at 800 °C (800A-CoOx/N-C) is 2.6 times higher than previously reported cobalt oxide on N-doped carbon synthesized with NH4OH (2A-CoOx/N-C). Over 70% of the butene dimers were linear C8 olefins for all catalysts. The oligomerization selectivity increased with 1-butene conversion. The catalysts were characterized by elemental analysis, N2 adsorption, X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS), and X-ray photoelectron spectroscopy (XPS). The nitrogen content of the catalysts increases with ammonia treatment temperature as confirmed by elemental analysis. The surface content of pyridinic nitrogen with a binding energy of 398.4 ± 0.1 eV increased with ammonia treatment temperature as evidenced by deconvolution of N 1s XPS spectra.

  • Prechemisorption of hydrogen on cobalt oxide gives rise to an extraordinarily active hydrogen for both isotopic exchange of ethylene and isomerization of butene, while the active part of prechemisorbed hydrogen is consumed within a short period to form butane as demonstrated by incorporation of prechemisorbed deuterium into butane. Both the ethylene and butene reactions take place on the common site of the active hydrogen as evidenced by an intermolecular hydrogen transfer in competitive runs. The competitive reaction discloses that ethylene is more strongly adsorbed than butene, and hence that the reacting olefin molecule is directly coordinated to cobalt ion priormore » to the reaction with hydride to form the alkyl-intermediate. The previously observed enhancements by hydrogen of butene isomerization and isotopic exchange of ethylene are ascribed to the formation of active hydrogen. No similar effect was found for H/sub 2/-D/sub 2/ equilibrium at -195 and -78/sup 0/C and for ethylene hydrogenation at room temperature.« less
  • We use density functional theory to describe a novel way for metal free catalytic reduction of nitric oxide NO utilizing boron doped graphene. The present study is based on the observation that boron doped graphene and O—N=N—O{sup −} act as Lewis acid-base pair allowing the graphene surface to act as a catalyst. The process implies electron assisted N=N bond formation prior to N—O dissociation. Two N{sub 2} + O{sub 2} product channels, one of which favoring N{sub 2}O formation, are envisaged as outcome of the catalytic process. Besides, we show also that the N{sub 2} + O{sub 2} formation pathwaysmore » are contrasted by a side reaction that brings to N{sub 3}O{sub 3}{sup −} formation and decomposition into N{sub 2}O + NO{sub 2}{sup −}.« less
  • Stereoselective hydrogenations of 1,3-butadiene and 2-methyl-1,3-butadiene over thorium oxide catalyst were investigated to elucidate the intermediates of the reactions. Hydrogenation of 1,3-butadiene produced predominantly trans-2-butene. Deuterium tracer studies provided direct evidence that 1,4-addition was a dominant mechanism. Deuteration of 1,3-butadiene yielded exclusively monoenes-d/sub 2/, while no deuterium was exchanged with hydrogen in 1,3-butadiene. Deuteration of 2-methyl-2-butene gave mainly (E)-2-methyl-2-butene-1,4-d/sub 2/. For both reactants, most stable conformations of starting diens (s-trans form) were reflected on the structure of the products. The geometrical structures as well as molecular identity of a hydrogen molecule were maintained during hydrogenation. Reaction of a mixture containingmore » 1-butene and 1,3-butadiene-d/sub 6/ in the presence of hydrogen revealed that 1-butene and 1,3-butadiene independently underwent isomerization and hydrogenation, respectively. The nature of their active sites is discussed. Key intermediate of the hydrogenation of conjugated diene is postulated to be the syn form of methyl- or dimethyl-..pi..-allyl carbanion which is hydrogenated before interconverting to their isomeric anti form of the ..pi..-allyl carbanion. 5 figures, 6 tables.« less
