Isomerization and Hydrogenation of cis-2-Butene on Pd Model Catalyst
The adsorption and kinetics of conversion of cis-2-butene with deuterium on model supported Pd catalyst (Pd/Fe3O4/Pt(111)) were characterized by reflection-absorption infrared spectroscopy (RAIRS), temperatureprogrammed desorption (TPD), and isothermal molecular beam (MB) experiments. It was found that selectivity toward cis-trans isomerization and hydrogenation depends critically on the nature...
متن کاملOxidative dehydrogenation of 1-butene to butadiene over carbon nanotube catalysts
The applications of carbon nanotubes (CNTs) as catalysts have attracted much interests in catalysis community due to their unique porous microstructure and chemical properties. One of the promising results is the use of CNTs in the oxidative dehydrogenation (ODH) of ethylbenzene to styrene [1,2]. However, only few works were reported on the use of CNTs or other carbonaceous materials to catalyz...
متن کاملGas-phase Β-pinene Isomerization over Acid-activated Bentonite
−− The kinetics of the gas-phase isomerization of β-pinene over an acid-activated bentonite clay has been investigated in a fixed-bed continuous flow reactor, at atmospheric pressure between 58 and 90 C. The major isomers produced were camphene, α-pinene and limonene. The reaction rates of β-pinene conversion and the apparent activation energy were determined. The kinetics of β-pinene isomeriza...
متن کاملPredicting Solubility of Isotactic Poly (1-Butene) in Different Organic Solvents by Modified UNIQUAC
The UNIQUAC activity coefficient model is extended to predict solid-liquid equilibrium of isotactic crystalline poly (1-butene), iPBu-1, in different organic solvents. The UNIQUAC activity coefficient model used in this work is based on the concept of group contribution and consists of combinatorial, residual and free volume terms. To account for branching of atom groups in the monomer structur...
متن کاملExpected nucleation effects of carboxylic acid salts on poly(1-butene)
9,10-Dihydro-9,10-ethano-anthracene-11,12-dicarboxylic acid disodium salt (DHEAS) was synthesized and used as a nucleating agent for poly(1-butene) (iPB). The isothermal crystallization kinetics of iPB having different nucleating agents were investigated by differential scanning calorimetry (DSC) and polarized optical microscopy (POM). The results showed that the nucleating agents increased the...
