55：Title: Predicting the viscosity of biodiesel fuels based on the mixture topological index methodSource: FUEL 86 (12-13): 1849-1854 AUG 2007Document Type: ArticleLanguage: EnglishCited References: 17 Times Cited: 0Abstract: To predict the viscosity of any given biodiesel fuel (FAME mixture), a novel topological index based on the distance matrix and adjacent matrix of the molecular structure is proposed. The new topological index can reflect the information of the molecular structure for fatty acid methyl ester (FAME), such as the size of molecular, unsaturated bond and branch degree. Combined with the modified Grunberg-Nissan or Hind equation, the topological index values of the FAME mixture were calculated. Then, relates the topological index values of the FAME mixtures with the viscosities of them, two linear regression equations were obtained. Using these regression equations, the viscosity of biodiesel fuels were predicted. The results show the modified Grunberg-Nissan equation with a higher precision of prediction than the Hind equation regression equation.

The catalytic activities of many metal oxides were evaluated, the influences of various operation conditions on the DEC yield were explored, and the catalytic mechanism was also analyzed. Among the tested catalysts, ZnO showed the best catalytic activity toward DEC synthesis. The optimum reaction conditions were as follows: ethanol/urea molar ratio of 10, catalyst concentration of 6%, reaction temperature of 463 K, reaction time of 5 h and the reaction pressure of 2.5 MPa, respectively. The highest DEC yield was 14.2%. The reaction of producing N-ethyl ethyl carbamate (N-EEC) was the main side reaction in this process, which consumed both ethyl carbamate and DEC. It is necessary to remove DEC from the reactor as quickly as possible. (C) 2007 Elsevier B.V.

The catalyst was characterized by infrared spectroscopy, scanning electron microscopy, X-ray, diffraction, and energy dispersive spectroscopy. Hydration and etherification reactions of isobutylene with an ethanol-water mixture to produce a fuel mixture were carried out over these catalysts. The effects of the preparation method and La loading on the catalytic performance of La/beta catalysts were studied, and the reaction mechanism was proposed. The results indicated that the ion-exchange degree and La loading of the La/beta catalyst prepared by the microwave heating method were higher than the one prepared by the conventional heating method, and the ion-exchange time was shorter. The conversion of water and ethanol over the modified La/beta molecular sieve catalyst was increased by 10% similar to 20% compared with the unmodified H beta molecular sieve, and the catalyst activity increased with the La loading. The hydration and the etherification mainly occurred on the external surface of the beta molecular sieve catalyst. Bridging Al-OH-Si acid sites, i.e., Bronsted acid sites, were the main active sites, and the carbonium ion was formed during the reaction.Author Keywords: beta molecular sieve; lanthanum; isobutene; ethanol; water; hydration etherification; microwave heatingKeyWords Plus: MICROWAVE IRRADIATION; ION-EXCHANGE; ETHANOL; ZNCL2Addresses: Yang BL (reprint author), Xian Jiaotong Univ, Dept Chem Engn, State Key Lab Multiphase Flow Power Engn, Xian 710049, Shaanxi Peoples R China

The product distributions were predicted using a new black-box model based on fuzzy neural network (FNN) combined with genetic algorithm (GA) named FNN-GA method. In this new approach, the fuzzy neural network model is constructed for correlating the values of input, namely feedstock components, operating variables with output, namely the yields of upgraded gasoline and the olefin fraction in it. And then, the inputs of operating variables are optimized using genetic algorithm with a view to maximize yields of upgraded gasoline and the restricting of olefin in the product gasoline. This new FNN-GA modeling and optimization can be conducted completely from the experimental data wherein the complicated knowledge of the reaction mechanisms, kinetics, mass and heat transfer are not required. Using artificial neural network (ANN)-GA strategy, a set of optimized operation conditions leading to maximized yields upgraded gasoline with olefin restrict for different feedstock were obtained. The experimental. results agreed well with the predicted ones and a significant improvement in the upgraded gasoline product were gained under the optimized operating conditions.

We describe a study in which enhanced green fluorescence protein (EGFP) was fused to the C terminus of a model protein glutathione S-transferase (GST) to optimize the chimeric protein production in Pichia pastoris by measurements of fluorescence of living cells in a 96-well microtiter plate using simple fluorescent scanning. Several common factors (e.g., time course of expression, effect of methanol concentration, frequency of methanol addition, medium pH) were tested using this strategy. Western blotting assay showed that the correct full-length GST-EGFP chimeric protein was expressed intracellularly in P. pastoris. The fluorescence intensity and GST bioactivity of cell extract yielded a direct correlation. The results show that the reported method provides an attractive platform for the optimization of recombinant protein production in vivo in real time as well as handling at least 96 samples in parallel.

Experiments on the physical adsorption capacity of matrix, retention time and pressure drop were carried out; the ability of bioreactor to buffer shock loading and the removal efficiency with different packing materials were also investigated. Besides, the kinetics of single-stage biodesulfuration was analyzed. The results showed that GAC provided higher bacteria adsorption capacity, showed a more resistance to shock loading and allowed better operational control with respect to pressure drop than other inert carriers. When the retention time was changed from 30 to 100 s at an influent concentration of 100 mg/ L of H2S, the removal efficiencies were above 98%; when the inlet concentration of H2S were changed from 110 to 120 mg/L, an average 96.8% removal efficiency was achieved during the long-term operation for GAC bioreactor. Next to GAC, wood chip was found to be a good packing material; however, peat moss and ceramic had limited effectiveness and their removal efficiencies were less of 90%. The kinetic analysis showed that the maximum removal rate and the half-saturation constant of the GAC bioreactor were 666.7 mg (H2S)/(L (.) d) and 20.8 mg/L, respectively. (c) 2005 Elsevier Ltd.

The products were characterized with scanning electron microscope (SEM), X-ray diffraction (XRD), energy dispersion spectrum (EDS) and size analysis. The SEM images showed that the Cu nanostructures were flower-like and made up of petals with an average thickness of about 90 nm. The XRD trace showed that the Cu nanostructures were of face-centered cubic lattice. The EDS analysis indicated that only a few of the Cu atoms in the nanostructures were oxidized, though no protective reagents were used in the synthesis procedure. A solid-solution-solid mechanism for the formation of the Cu flower-like nanostructures was discussed. (c) 2005 Elsevier B.V.

Several operational variables which have an influence on the yield of DMC, such as the total feed flow rate, bottom temperature, pressure, reflux ratio, mass ratio of the reactants, the concentration of the catalyst and the stirring speed, were investigated to achieve an optimum operation. Under these optimized settings, the highest yield of DMC obtained was 92.2%. A high concentration and purity of DMC in the overhead products, more than 17%, was gained in the reactive rectifying conditions.

47 Title: Preparation of CeO2/ZnO nanostructured microspheres and their catalytic propertiesSource: POWDER TECHNOLOGY 166 (2): 72-76 AUG 21 2006Document Type: ArticleLanguage: EnglishCited References: 12 Times Cited: 0Abstract: CeO2/ZnO nanostructured microspheres with an average diameter of about 3.8 mu m were synthesized by a solid-stabilized emulsion route. The CeO2/ZnO nanostructured microspheres were characterized with SEM, XRD, CO2-TPD, BET measurement and size analysis. Based on the oxidative coupling reaction of methane with carbon dioxide as an oxidant, the catalytic performance of the CeO2/ZnO nanostructured microspheres was evaluated and compared with that of the CeO2/ZnO nanoparticles. The results showed that the surfaces of the CeO2/ZnO nanostructured microspheres consisted of petal-like structures with a petal thickness of about 90 nm and a petal depth of 0.4 mu m to 0.9 mu m. Using CeO2/ZnO nanostructured microspheres as catalysts for the oxidative coupling of methane with carbon dioxide, the conversion of methane corresponded with that using the CeO2/ZnO nanoparticles, while the CeO2/ZnO nanostructured microspheres had much longer operating life.
