| 摘 要： | 采用煤质活性炭作载体,分别用HNO3、H2O2和(NH4)2S2O8进行预处理,然后用浸渍法负载PdCl2,在H2流中还原得到Pd/C催化剂,用于肉桂醛(CAL)选择加氢制氢化肉桂醛(HCAL)的反应。考查了Pd负载量,反应温度和压力对加氢反应的影响,优化了反应条件。进一步考查了助剂Fe、Co、Ni1]对反应的影响。最终,CAL转化率为98%,HCAL选择性为88%。

| Abstract: | Coal-based activated carbon was pretreated with HNO_3,H_2O_2 and(NH_4)_2S_2O_8 before selected as support.A series of Pd/C catalysts were prepared by means of impregnation and with PdCl_2 as precursor.It was reduced in H_2 stream,and applied to selective hydrogenation of cinnamaldehyde to hydrocinnamaldehyde.Effects of Pd-loading,reaction temperature and pressure were discussed.In addition,promoters of Fe,Co,Ni were introduced to the catalysts.At last proper conditions for the reaction were found,and 88% selectivity to HCAL at 98% conversion of CAL was obtained. |
