Abstract: This invention is related to a preparation method of a supported catalyst Mo—O—K-MexOy for the synthesis of methanethiol from H2S-containing syngas. The catalyst comprises of an active component of Mo—O—K-based species, an active promoter and a support denoted as metal (or metals)-carrier. The support is prepared by electroless plating method in such a way that the metal or metals chosen are plated onto the surface of the carrier. Transition metal, especially Fe, Co or Ni are selected to be the plating metal, while SiO2, Al2O3 or TiO2 are selected to be carrier. The catalyst thus prepared is found to be efficient for the synthesis of methanethiol from H2S-containing syngasor carbon oxides/hydrogen mixtures, especially regarding a minor formation of the by-product CO2.

Abstract: A method is described to prepare a Mo containing supported catalyst comprising TeO2 as active promoter and a process for preparing methanethiol in the presence of said catalyst.

Abstract: The invention provides a topology collection method and dual control board device applicable to a stacking system comprising dual control board devices. A master control board of a dual control board device advertises through a stack port the topology information of the member device in which the master control board resides, including information about the master control board and, if a slave control board is present, information about the slave control board; and stores the topology information or updates the existing topology information upon receiving the topology information of the stacking system through the stack port, and backs up the stored topology information of the stacking system to the slave control board after the slave control board is inserted. This invention is applicable for collecting the topology information of a stacking system comprising distributed dual control board devices.

Abstract: The present invention refers to a continuous process for the manufacture of methyl mercaptan using Mo—O—K-based catalysts. It is further described that the total selectivity of methylmercaptan can be increased by at least 1% by lowering the total gas hourly space velocity. The invention further refers to a process for the preparation of a solid, preformed catalyst system.

Abstract: The multi-layer bamboo plywood with high work strength isn't liable to warp, characterized in that said plywood is composed of bamboo strips or strip-shaped bamboo compositing materials that are superposed and glued one with respect to another, the side of said plywood is provided with a through hole running through the plywood perpendicular to said side, tensioned wires with high tenacity and elasticity are provided within said through hole and a fastening assembly is disposed at the end of said wires. The advantages of this invention consist in high strength, excellent abrasion resistance and being not liable to warp, which contribute to flat connection in series and long service life. Said bamboo plywood is a perfect substitute for lumber, and the wide use thereof will remarkably save lumber and thereby protect the forest resources.
