The metal oxides CuMnce and ceY washcoats on cordierite were prepared using an impregnation method, and then used as support for the active Pt component to prepare the Pt/CuMnce and Pt/ceY monolithic catalysts for the deep oxidation of VOCs. In comparison with the Pt/ceY, CuMnce, and ceY monolithic catalysts, the Pt/CuMnce monolithic catalyst shows an excellent performance for toluene,ethyl acetate,and n-hexane oxidation and the Tis low to 216, 200 and 260 ℃,respectively. The active components Pt/PtO and CuMnce result in a better synergetic interaction, which promote the catalyst reducibility, increase the oxygen mobility, and enhance the adsorption and activation of organic molecules.

建立了双轮共转起落架的摆振非线性动力学模型,并采用分岔计算方法对模型进行了稳定性求解,形成了一套适用于摆振分析的分岔计算方法。在此基础上,对轮间距和双轮共转对摆振稳定性的影响进行了分析。轮间距的增加能有效减小侧向摆振的发生区域,对扭转摆振区域则相反,且可能引起摆振区域拓扑结构的改变。双轮共转仅在轮间距较大的情况下,对侧向摆振起到抑制作用。

In this work, a dual-phase material consisting Gd0.1ce0.9O2-δ （GDC, 60 wt%） was synthesized. of La0.7Ca0.3Cr0.95Zn0.05O3-δ （LCCZ, 40 wt%） and Properties including phase structure, sintering behavior, electrical conductivity and oxygen permeability for LCCZ-GDC were evaluated. The results show that dense LCCZ-GDC dual-phase disks were obtained at the sintering temperature of 1250, 1300, 1350 and 1400 ℃ by tape casting and high temperature sintering method. The grain sizes of both GDC and LCCZ grew up with the increasing of sintering temperature. The average grain size of GDC was about 0.5, 0.8, 1.4, 1.8 μm while the average grain size of LCCZ was about 0.8, 1.5, 1.8 and 2 pm after sintering at 1250, 1300, 1350 and 1400℃, respectively. Oxygen flux of LCCZ-GDC decreased with the increase of sintering temperature from 1250 to 1400 ℃. The oxygen flux of LCCZ-GDC sintered at 1250 ℃ reached 0.079 mL/min/cm2 at 975℃ with a membrane thickness of 800 μm. Dual-phase material of LCCZ-GDC will be a promising oxygen transport membrane material for its low sintering temperature and good microstructure.
