主　　题：Zr VERY HIGH SELECTIVITY TO ETHYLENE REACTION OF CARBON MONOXIDE AND HYDROGEN ON M-Zr CATALYSTS 

摘      要：Hydrogenation of carbon monoxide over M-Zr catalysts selectivelyproduces ethylene（90%）in a short time at 360℃,in the stream of 0.8MPa syngas（H/CO=4.5/1）with a space velocity of 345 *** distribution of formed hydrocarbons does not obey the *** of the catalysts makes them be deactivated in 3 *** and Ncan recover CO conversion of catalysts（the former even en-hance it greatly）,but can not recover their selectivity to *** be-haviour of M-Zr catalysts seems to be controlled by their acidity and basici-ty.
