英文摘要: The Cu-Co-Fe-1.2/Al2O3 alcohol synthesis catalyst was prepared from the alumina support modified with HNO3 or KOH aqueous solution at different pH. The effects of modification conditions on the phase, surface and reduction behavior of the catalyst were studied. With increasing pH value, the dispersion of CuO on the support becomes easier and the mean pore size of the catalyst decreases. The Co component is well dispersed on the support modified at low pH. The reduction temperature of the catalyst decreases at first, and then increases when the Al2O3 support is modified at pH of 6 to 13.
