| 1 | Selective methanation of carbon monoxide in hydrogen rich stream over Ni/CeO_2 nanocatalysts显示文摘In the present work, selective methanation of carbon monoxide in hydrogen rich stream was investigated over Ni/CeO2 nanocatalysts. The obtained results revealed that increasing in nickel loading decreased the BET surface area, pore volume and nickel dispersion. The 25% Ni/CeO2 with a NiO crystal size of 12 nm exhibited the highest activity in CO methanation reaction and reached to maximum CO conversion and CH4 selectivity at temperatures above 230 ℃. The catalytic results revealed that CO selective methanation well progressed at lower temperatures while CO2 methanation was completely suppressed until CO conversion reached to maximum value. | Behzad Nematollahi Mehran Rezaei Ebrahim Nemati Lay | 2015 | Journal of Rare Earths2015，33，6： | 6 |
| 2 | Thermodynamic analysis of combined reforming process using Gibbs energy minimization method: In view of solid carbon formation显示文摘Thermodynamic analysis was applied to study combined partial oxidation and carbon dioxide reforming of methane in view of carbon formation. The equilibrium calculations employing the Gibbs energy minimization were performed upon wide ranges of pressure (1-25 atm), temperature (600-1300 K), carbon dioxide to methane ratio (0-2) and oxygen to methane ratio (0-1). The thermodynamic results were compared with the results obtained over a Ru supported catalyst. The results revealed that by increasing the reaction pressure methane conversion decreased. Also it was found that the atmospheric pressure is the preferable pressure for both dry reforming and partial oxidation of methane and increasing the temperature caused increases in both activity of carbon and conversion of methane. The results clearly showed that the addition of O 2 to the feed mixture could lead to a reduction of carbon deposition. | Behzad Nematollahi Mehran Rezaei Ebrahim Nemati Lay Majid Khajenoori | 2012 | Journal of Natural Gas Chemistry2012，21，6： | 4 |

| 4 | Thermo-magnetic analysis of thick-walled spherical pressure vessels made of functionally graded materials显示文摘This study presents an analytical solution of thermal and mechanical displacements, strains, and stresses for a thick-walled rotating spherical pressure vessel made of functionally graded materials (FGMs). The pressure vessel is subject to axisymmetric mechanical and thermal loadings within a uniform magnetic field. The material properties of the FGM are considered as the power-law distribution along the thickness. Navier’s equation, which is a second-order ordinary differential equation, is derived from the mechanical equilibrium equation with the consideration of the thermal stresses and the Lorentz force resulting from the magnetic field. The distributions of the displacement, strains, and stresses are determined by the exact solution to Navier’s equation. Numerical results clarify the influence of the thermal loading, magnetic field, non-homogeneity constant, internal pressure, and angular velocity on the magneto-thermo-elastic response of the functionally graded spherical vessel. It is observed that these parameters have remarkable effects on the distributions of radial displacement, radial and circumferential strains, and radial and circumferential stresses. | M. A.

| 5 | Facile and one-pot,electro-organic synthesis of a new bis-quinone by the ECCE mechanism in green media显示文摘Electrochemical oxidation of 4-methyl catechol(1a) is investigated in the presence of 1,3-indandione(3)as nucleophile in phosphate buffer solution(0.2 mol/L,pH 6) mixed with ethanol as organic green solvent(50/50) using cyclic voltammetry and controlled-potential coulometry.The results indicated thatquinones derived from electro-oxidation of 1a,participated in a 1,4-Michael addition reaction with1,3-indandione(3) under ECCE mechanism.In this direction,a new bis-quinone was synthesized in high yield and good purity using a facile and convenient electrochemical pathway by carbon anode electrodes in an undivided cell. | Mohsen Ameri Alireza Asghari Ali Amoozadeh Mohammad Bakherad Davood Nematollahi | 2014 | Chinese Chemical Letters2014，25，12： | 2 |
