摘要

用磷酸溶液(H3PO4)对活性炭载体(AC)进行预处理

以此为载体

采用浸渍法制备了负载型钯(Pd)催化剂(PACT)并将其应用于乙炔氢氯化反应.结果表明

与未进行处理活性炭载体负载Pd催化剂(PAC)相比

催化剂PACT表现出较高的催化剂活性.对催化剂进行了比表面积(BET)

Boehm滴定

X-射线粉末衍射(XRD)

透射电镜(TEM)

电子能谱(EDS)等表征.结果表明

载体表面含氧基团含量的变化

活性组分Pd含量的富集以及由H3PO4引进的PO3-4的存在是催化剂具高活性的主要原因.热重分析(TG)说明

反应过程积碳的产生使得催化剂的活性降低.

Abstract

Activated carbon(AC) pretreated with phosphoric acid(H3PO4) supported Pd catalyst(PACT)was prepared using the impregnation method.Catalytic activity of the catalyst was evaluated in the acetylene hydrochlorination reaction.The results show that the catalyst yield superior catalytic performance compared to the catalytic(PAC)

in which the activated carbon support was untreated.The characterization of surface area(BET)

Boehm titration measurement

X-ray di?raction(XRD)

transmission electron microscopy(TEM)

and energy-dispersive spectrometry(EDS) demonstrated that concentration of acidic oxygen-containing functional groups on the surface of the PACT

Pd-containing active species and introducing PO3-4by H3PO4were responsible for the high activity of the optimal Pd catalyst.Thermo Gravimetric analysis(TG) indicated that carbon deposition produced by the reaction lead to the decrease of activity.
