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 SiO 2 , Al 2 O 3 or TiO 2 are selected to be carrier. The catalyst thus prepared is found to be efficient for the synthesis of methanethiol from H 2 S-containing syngasor carbon oxides/hydrogen mixtures, especially regarding a minor formation of the by-product CO 2 .
专利号:US-5139940-A 优先权日:1989-10-26 标题 :Activation compounds and methods of synthesis of activation compounds 发明人:ISAACS STEPHEN T; CIMINO GEORGE D; METCHETTE KENNETH C; TESSMAN JOHN W 权利人:ISAACS STEPHEN T; CIMINO GOERGE D; METCHETTE KENNETH C; TESSMAN JOHN W 摘要:The invention is directed to isopsoralen compound compositions that contain a variety of substitutions which yet permit their binding to nucleic acid polymers. Reaction conditions that activate these bound isopsoralens results in covalent crosslinking to the nucleic acid polymers. The resultant complex is inhibited from being a template for the template-directed enzymatic synthesis of a complementary nucleic acid polymer. Beside the isopsoralens compositions, the invention includes their synthesis, the nucleic acid complex production and detection, and the above inhibitory method of use of the isopsoralens.

Thanks to the carbon matrix, the catalysts provided herein can be corrosion resistant, self-healing, more cost-effective, and can have higher catalytic activity. The synthesis of the catalyst and its properties can furthermore be improved compared to catalysts formed from a complex including a chelating.
