The Mo ions with high valence state in La_0.5Sr_0.5Fe_0.9Mo_0.1O_{3- δ} (LSFM) were partially substituted by trace amounts of Ni, which was found to weaken the structural stability of La_0.5Sr_0.5Fe_0.9Mo_0.1O_{3- δ} under reducing atmosphere. In this way, Fe⁃Ni alloy nanoparticles precipitated on the surface of the oxidized perovskite under reducing atmosphere, and a composite anode then be prepared showing improved catalytic properties, electrochemical characterizations of which were evaluated. The experimental results indicate that power densities of single cell using La_0.5Sr_0.5Fe_0.9Mo_0.07Ni_0.03O_{3- δ} (LSFMN0.03) as anode are 0.84 W/cm² and 0.62 W/cm² (800 ^oC) with polarization resistance of 0.35 Ω · cm² and 1.01 Ω · cm² (800 ^oC) under H₂ and CO fuels, respectively. The performances of cell with LSFMN0.03 anode are obviously higher than that of La_0.5Sr_0.5Fe_0.9Mo_0.1O_{3- δ} anode. The results of stability tests indicate that, the cell with LSFMN0.03 anode could maintain an excellent electrochemical stability, when the H₂ content in H₂/CO mixture fuel is more than 40%.

A multi-directional analysis for the application of oil shale residue in the field of chemical industry and environment and the heap abandonment present situation of the oil shale residue is proposed. It is found that there are six limitations in recycling oil shale residue in the field of environment and chemical industry, which lead to the difficulty of proper and reasonable disposal of oil shale residue. The environmental pollution caused by oil shale residue is still serious. Based on the indepth discussion of the local limit, a new idea for disposing the oil shale residue is presented, which uses the oil shale residue to prepare bulk material of large social needed, and the preparation process is simple and the secondary energy consumption is less.

The stability of emulsion of Shengli crude oil and variation of drop size were investigated using LUMisizer-LS610. At the same time, the influences of the emulsifier concentration，the wateroil ratio, temperature and electrolyte on the stability of emulsion and the drop size were also explored. The results show that the higher emulsifier concentration is, the smaller the drop size would be and the more stable crude oil emulsion is. The greater the proportion of oil phase in emulsion, the more stable the emulsion is. As the temperature increases, the good emulsified effect is obtained, however, the stability of the emulsion is reduced. The electrolyte can enhance the stability of the emulsion and reduce the drop size.

Mesoporous Y Zeolites were prepared by alkaline solution etching method using industrial NaY zeolite powders as raw materials. The crystal structure of the samples was characterized using Xray diffraction (XRD) and skeleton Fourier transform infrared spectroscopy (FTIR). The pore structure and morphology were measured by N2 adsorption isotherms and scanning electron microscopy (SEM). The acid properties were characterized using pyridineinfrared spectroscopy (PyFTIR) technique. The results show that NaY zeolites can maintain the topology of zeolite crystal and basic morphology structure after treated in a suitable concentration by alkaline solution at mild conditions. A defected mesoporous structure in the zeolite is obtained in the process of alkaline solution etching. In addition, the alkali etching has little effect on the amount of B acid sites of H type zeolites, while, the number of L acid centers greatly reduces in the mesoporous Y Zeolites. 

The thermodynamic simulation analysis for methanol steam reforming hydrogen production system of kilowatt proton exchange membrane fuel cell was researched by Aspen Plus software. The influences of water to methanol mole ratio (0.8~1.6), reaction temperature (140~400 ℃), and pressure (101.325~506.625 kPa) on methanol steam reforming process were investigated. The results show that the methanol equilibrium conversion and CO mole fraction increase when the temperature is raised, while the H2 mole fraction decreases at the same time. The equilibrium conversion of methanol decreases with pressure increasing, but the pressure has little effect on the mole fraction of H2 and CO. The equilibrium conversion of methanol is improved with the water to methanol mole ratio raising. However, a large number of water vapor will increase the load of the system and lower the thermal efficiency. Therefore, the appropriate range of water to methanol mole ratio is between 1.2 and 1.4. It can be found that H2 mole fraction is 64.27% and CO content is below 10-5 ultimately through simulation of the hydrogen source system, which can provide hydrogen source for kilowatt proton exchange membrane fuel cell.

The CuHY zeolites adsorbents with different Cu loadings were prepared via impregnation method. The crystal structure of the adsorbent was characterized by XRD, and the surface acidity was measured by PyFTIR technique. The adsorption desulfurization performance was evaluated using fixed bed method with a WK2D micro coulometer analyzer. The results show that the adsorbents have the best adsorption desulfurization ability when the copper loading is 4%. The adsorption desulfurization performance becomes better with the decrease of the ratio of B acid amount and L acid amount. However, the adsorption desulfurization ability reduces severely, when copper loading is too large which results the surface copper oxide species, even though there is no B acidic sites existing on the surface of the adsorbent.

SnCu/C and SnCuM/C catalysts with different auxiliaries for hydrochlorination of acetyleneactivated carbon as the carrier has been treated with the concentrated nitric acid and Sn,Cu and other metal chloride as active componentswere prepared by the wet equivalentvolume impregnation and characterized by XRD and BET.

Then, optimized reaction conditions，reaction temperature 170 ℃，space velocity 30 h-1，feed volume ratio V(HCl)/V(C2H2) 1.05，were obtained in atmospheric fixed bed reactor. The catalytic performances of SnCu/C and SnCuM/C catalysts with different auxiliaries was investigated under the optimized reaction conditions. The experimental results show that SnCu/C catalyst has good initial activity，the acetylene conversion and the selectivity of chloroethylene is over 980%.The catalytic activity and stability are improved after adding to the different auxiliaries under the metionaboved reaction conditions，the acetylene conversion and the selectivity of chloroethylene is over 98.0%. 

The interfacial tensions (IFTs) between zwitterionic surfactant, hexadecyl diethyl2hydroxy1proply sulfobetaine and Shengli crude oil were investigated using spinning drop method. The influences of salinity, concentration of divalent ions and weak base NaHCO3 on IFT were discussed. The experimental results show the mixed adsorption of betaine molecules and the active components present in the crude oil at the interface and the synergism of them together determine the IFT of oilwater. The betaine surfactant with electroneutrality permits closer packing at the interface. An increase in the concentration of Na+ and Mg2+ with less ion radii appears to decrease the IFT gradually, however, the value of IFT remain at higher level with increase in the concentration of Ca2+ with larger ion radius. NaHCO3 can react with the active components present in the crude oil, which reduces IFT to ultralow value. In this case, one can find that total salinity is the key factor that determines the IFT, while ionic type has little effect on the IFT.

Fushun shale oil as the research object was investigated. In laboratory an ultrasonic demulsification technology was used to intensify demetalization of shale oil. The effect of various parameters on demetalization of Fushun shale oil were discussed, which were ultrasound-assisted, demetalization agent type and dosage, demulsifier type, subsidence time on the removal of the Fe, Ca, Na and Mg impurity. The demetalization effect with ultrasonic radiation was much better than that without under the suitable conditions. In ultrasonic radiation, the metal removal effect is the best when the demetallization agent(ETCF) mass fraction was 2 500 μg/g and demulsifier R203A, the settling time was 4 h. Under these condition the removal rate of Fe is 80%, and the removal rate of Mg is 90%.
