A　series　of　K　modified　Ag-Fe/ZnO-ZrO2　catalysts　were　prepared　by　co-precipitation　method　under　different　calcination　temperatures.　The　effect　of　calcination　temperature　on　the　catalytic　performance　for　higher　alcohols　and　dimethyl　ether　(DME)　synthesis　from　CO　hydrogenation　was　investigated.　The　catalysts　were　characterized　by　nitrogen　adsorption,　XRD,　H2-TPR　and　CO-TPD.　The　results　showed　that　the　catalyst　calcined　at　250℃　could　not　reach　the　optimal　performance　due　to　insufficient　active　sites　formed　at　the　lower　calcination　temperature.　The　catalyst　calcined　at　300℃　exhibited　highest　CO　conversion　and　higher　selectivity　of　higher　alcohols　and　DME　and　highest　space　time　yield　of　higher　alcohols　and　DME　reached.　As　the　calcination　temperature　increased　further,　the　CO　conversion　decreased,　while　the　selectivity　of　higher　alcohols　decreased　at　first　and　then　increased,　the　selectivity　of　DME　increased.　The　catalytic　performance　of　the　catalyst　was　mainly　related　with　its　specific　surface　area,　reduction　capacity,　the　dispersion　of　the　σ-AgFeO2　species　and　CO　adsorption-desorption　properties.　It　was　proved　that　the　catalyst　with　larger　specific　surface　area,　being　easily　reduced,　higher　dispersion　of　σ-AgFeO2　specie　and　more　CO　adsorption　active　sites,　would　be　helpful　for　CO　hydrogenation　conversion.　The　decrease　of　the　non-dissociative　adsorption　strength　for　CO　on　the　surface　active　sites　of　the　catalyst　is　favorable　for　the　generation　of　higher　alcohols　and　DME,　while　the　increase　of　the　dissociative　adsorption　strength　for　CO　is　not　favorable　for　the　formation　of　hydrocarbons.　©,　2015,　Ranliao　Huaxue　Xuebao/Journal　of　Fuel　Chemistry　and　Technology.　All　right　reserved.
