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.

Claim (Index 16):
The olefin metathesis catalyst according to claim  1 , wherein the catalyst additionally contains one or more platinum group metals selected from the group consisting of platinum (Pt), palladium (Pd) and rhodium (Rh) at the concentration of up to 3 weight part by the total weight of the catalyst.
