摘要： A supported core-shell bimetallic catalyst with high selectivity, and preparation method and an application thereof are provided. SBA-15 is used as support, platinum (Pt) is used as active component, 3d transition metal is used as cocatalysts. In the core-shell bimetallic catalyst formed by the 3d transition metal and Pt, in one aspect, by the addition of the 3d metal in the core, the d-band center of surface Pt atoms is down shifted, and the absorption of propylene is weakened, thereby improving the selectivity for propylene. In another aspect, the use of Pt is reduced by the addition of the 3d transition metal, improving the utilization of Pt. The catalyst is applicable in a hydrogen atmosphere, has a good effect on the preparation of propylene by propane dehydrogenation and causes high dehydrogenation activity under high temperature conditions. The total selectivity for propylene may reach 85%, which achieves high propylene selectivity.

摘要： The present invention relates to an olefin metathesis reaction catalyst where rhenium (Re) oxide or molybdenum (Mo) oxide is supported, as a catalyst main component, on a surface-modified mesoporous silica or mesoporous alumina support, and a preparation method therefor. The olefin metathesis reaction catalyst of the present invention allows highly efficient metathesis of long-chain unsaturated hydrocarbons having at least eight carbons at a low temperature of 150° C. or lower. The catalyst can be separated readily from reaction solution, regenerated at a low temperature of 400° C. or lower by removing toxins accumulated on it during the metathesis reaction, and used repeatedly in metathesis reaction many times, thereby being made good use in commercial olefin metathesis processes.

摘要： Embodiments of processes for producing propylene utilize a dual catalyst system comprising a mesoporous silica catalyst impregnated with metal oxide and a mordenite framework inverted (MFI) structured silica catalyst downstream of the mesoporous silica catalyst, where the mesoporous silica catalyst includes a pore size distribution of at least 2.5 nm to 40 nm and a total pore volume of at least 0.600 cm3/g, and the MFI structured silica catalyst has a total acidity of 0.001 mmol/g to 0.1 mmol/g. The propylene is produced from the butene stream via metathesis by contacting the mesoporous silica catalyst and subsequent cracking by contacting the MFI structured silica catalyst.
