Preparation method of loaded catalyst for improving selective hydrogenation of citronellal

The invention discloses a preparation method of a loaded catalyst for improving selective hydrogenation of citronellal. The loaded catalyst refers to a catalyst obtained by loading an active componenton a carrier; when the catalyst carrier is an imporous carrier, a poisoned loaded catalyst is obtained by performing a reaction on a poisoning agent having the kinetic diameter larger than that of atarget selective reactant and the previously prepared loaded catalyst while thoroughly stirring; the poisoning agent refers to all nitride that can interact strongly with the active component. By thepreparation method, the chemoselectivity of the catalyst is precisely controlled by the nitride poisoning agent, so that the selectivity of the citronellol can be significantly improved by virtue of molecular size selectivity and selectivity of exposed chemical reaction sites while 98% of the conversion rate is maintained. 本发明公开了种提高香茅醛选择性加氢的负载型催化剂的制备方法，该负载型催化剂是指活性组分负载在载体上的催化剂，当催化剂载体为有孔载体时，使用动力学直径大于载体孔尺寸的毒化剂与预先制备的负载型催化剂进行充分搅
