| description | A modified activated carbon supported rhodium type catalyst for high carbene hydrocarbon hydrogen formylation reaction is provided. The preparation of the catalyst comprises the techniques such as carrier pretreatment-activity rhodium solid-phase bound reagent combination, and used for gas-liquid-solid three phase catalyst system, which is characterized in that: a certain amount of alkali or alkaline earth metal hydroxide and salt modification activated carbon is used as a carrier, and the supported rhodium catalyst is prepared by using multiple impregnation method. The catalyst of the present invention is high in activity and selectivity. The catalyst is easy to be separated from products after reaction, capable of being used repeatedly, stable in performance, and suitable for the production process of high carbene hydrocarbon or mixed olefin hydrogen formylation made high carbon aldehyde, which has good industrial application value. |
