摘要

本文采用一锅法(PM)和等体积浸渍法(IM)制备了铋基催化剂并考察了PM的制备条件对催化剂的影响.使用固定床反应器对催化剂进行评价.结果显示

PM催化剂具有较好的催化活性

此时的制备条件如下:反应温度为160?C

反应时间为2 h.对催化剂进行XRD

BET

EDS和SEM等表征

结果表明

PM催化剂具有微球形貌

提供丰富的孔道结构

较大的比表面积和更多的活性位点

改善了催化剂的催化性能.除此之外

反应中积碳可能是导致铋基催化剂失活的一个原因.

Abstract

In this work

Bi-based catalysts were prepared by one pot method(PM)and incipient wetness impregnation method(IM)and preparation conditions of the PM were researched.Catalytic activity of catalysts was evaluated using a fixed-bed reactor for acetylene hydrochlorination.The results displayed that the PM catalyst was prepared at 160?C for 2h possessed a superior catalytic performance compared to the IM catalyst.The characterizations of XRD

BET

EDS and SEM demonstrated that the PM catalyst was microspheres structure

which could provide richer channel structures

larger specific surface areas and more active centres

thus improving the catalytic performances of catalysts.In addition

carbon deposition in the reaction was a possible reason for Bi-based catalysts deactivation.
