英文摘要	Modified aluminum alkoxide prepared by alcoholysis was used as an aluminum source in the complete liquid-phase technology for the preparation of slurry catalysts. the use of the modified aluminum alkoxide afforded control over the rate of the hydrolysis/condensation reactions during the preparation of the catalyst precursors, thereby generating catalysts with a fine nano-structured active metal and metallic oxide particles'. four types of cu-zn-al (molar ratio is 2:1:4) catalysts were prepared using different procedures. these catalysts were tested for co hydrogenation at 553 k, 4.0 mpa and h-2/co = 1.0 in a kettle with a mechanical agitator. the results indicated that the activity of the catalysts was greatly dependent on the rate of the hydrolysis/condensation reactions, and the catalyst with the best catalytic performance was obtained by controlling the hydrolysis/alcoholysis rate during catalyst synthesis by pre-alcoholysis of aip as the aluminum source, over which the co conversion and dimethyl ether selectivity could reach 62.6% and 62.5%, respectively.
