An experimental preparation of feedstock gas for methanol srnthesis by methane reforming with steam and CO2 has been investigated with newly prepared nickel-based catalyst SYM-1 in a simulated industrial theperature vanable fixed bed. It has been shown tha SYM-1 Catalyst was not deactivated during 500 h test and the synthesis gas for methanol production in industry can be prodaced This catalyst had excellent activity and the methane conversion reahed 95%. There was almost no carbon deposition on SYM-1 catalyst after lifetime test, and it had good mechanic strength. Pore distribution and XRD characterization show that the structure and properties of SYM-1 catalyst remained unchanged during lifetime test.

吸引社会资本投资于公用事业并使之得到合理回报,是国务院确定的一项重要政策。影响社会资本合理回报的主要指标应是:投资回报率、服务价格、投资运营成本。服务价格和成本的确定,存在着深刻的内在的矛盾,都不宜作为确定合理回报的先行指标。以投资回报率为先行指标,进而科学地设置其他两项指标,是解决社会资本合理回报的优化选择。

The reflection and refraction of SH plane wave at the interface between two inhomogeneous half-spaces are studied in this paper,where the distributions of shear modulus and mass density all obey the parabolic *** on the fundamental solution of the wave equation,the general formulations of incident wave,reflected wave and transmitted wave are *** the formulations into the boundary condition at the interface,the unknown coefficients are obtained,where the absolute values of these coefficients represent the amplitudes of reflected wave and transmitted wave.A series of parametric discussion are made to exhibit the effect on the reflection and refraction by wave number,incident angle and material properties.
