Abstract: 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.

Abstract: Disclosed herein is a system for recovering carbon monoxide from an industrial by-product gas, the system including a supply unit for supplying an industrial by-product gas containing carbon dioxide, nitrogen, carbon monoxide, and hydrogen, a first membrane separation unit including a separation membrane capable of allowing carbon dioxide and hydrogen to permeate, and receiving the industrial by-product gas supplied from the supply unit to allow carbon dioxide and hydrogen to permeate, and a second membrane separation unit including a polymer membrane in which a transition metal is supported, and receiving a gas remaining in the first membrane separation unit to allow carbon monoxide to permeate.
