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 11):
An olefin metathesis catalyst, in which rhenium (Re) oxide or molybdenum (Mo) oxide is supported on the surface-modified mesoporous alumina support which is characteristically prepared by the processes of reacting the \u2014OH group existing on the surface of the mesoporous silica support with a compound in which 1\u02dc4 C 1 -C 5  alkoxy groups are linked to a element selected from the group consisting of Si, Nb, Fe, Co, Zn, Ga and Sn in order to graft the compound on the surface of the support; and eliminating the unreacted compounds from the support, followed by calcining.
