| abstract |
The invention discloses a catalyst for producing higher alcohols by hydrogenation of CO and a preparation method thereof. The catalyst comprises an active component, an auxiliary agent and a carrier; wherein the active component is Co, and the auxiliary agent is selected from rare earth elements, alkaline earth metals, Ti One or more of , Mn, Zr, Cu, Al or B, and the carrier is silicon-modified petroleum coke-based activated carbon. The preparation method includes (1) preparing silicon-containing petroleum coke; (2) preparing a composite oxide containing active component Co and auxiliary elements; (3) combining the silicon-containing petroleum coke obtained in step (1) into step (2) The obtained composite oxide and the activator are mixed, the mixture is uniform, and then activated, and finally, the catalyst for producing higher alcohol by CO hydrogenation is obtained after washing and drying. The catalyst prepared by the method of the invention has the advantages of large specific surface area, good dispersion of active components, high reaction activity, high selectivity of high-carbon alcohol, and simple preparation method. |
