A　thermodynamic　analysis　was　carried　out　in　the　synthesis　of　C1-C5　alcohols　from　CO2　hydrogenation.　Lower　reaction　temperatures　were　of　advantage　to　the　formation　of　C1-C5　alcohols.　Chemical　equilibrium　compositions　of　the　reaction　system,　equilibrium　yields　of　alcohols,　and　equilibrium　conversions　of　reactants　at　different　temperatures,　pressures,　and　n(H2)/n(CO2)　were　obtained　by　minimizing　Gibbs　free　energy.　The　thermodynamic　analysis　could　be　utilized　to　evaluate　catalytic　performances　and　could　further　direct　development　of　catalysts.
