摘要
采用活性评价研究了沉淀温度对CuO/CeO_2水煤气变换催化剂的活性及热稳定的影响。结果表明:沉淀温度80℃和95℃合成的Cu O/Ce O_2催化剂水煤气变换活性较好;沉淀温度80℃合成的CuO/CeO_2催化剂耐热后活性较好,且相对失活率最低。
Effects of precipitation temperature for preparing the Cu O/Ce O_2 catalyst on the activity and thermal stability of the catalyst in water gas shift reaction were investigated by active evaluation. Results showed that the catalysts prepared at the precipitation temperature of 80℃ and 95℃ had higher catalytic activity, moreover, the catalyst prepared at 80℃ exhibited better thermal stability and lower deactivation speed.
