Title

Trimetallic Au-Cu-La/AC for Acetylene Hydrochlorination in a Multi-Tubular Fixed Bed Reactor

Author(s)

Keywords

Mercury-free catalyst

Acetylene hydrochlorination

Gold

Multi-tubular fixed bed reactor

Abstract

The metal chloride of LaCl3 was chosen to modify the Au-Cu/AC to decrease the noble metal of gold and enhance the catalytic performances. Then a lank">mercury-free catalyst of Au-Cu-La/AC was prepared by the impregnation method, and the fresh Au-Cu-La/AC and Au-Cu/AC catalysts were also characterized in comparison. The catalytic performances of lank">mercury-free catalysts for lank">acetylene hydrochlorination were carried out for 3500 hours in a multi-tubular fixed bed reactor. The additives of La can make the active species dispersed well and retard the aggregation of particles. And the acetylene conversion rate remained stable over 98. 5% with the fluctuations, less than 1%, and the selectivity of vinyl chloride maintained the stability of 99% or higher, which indicated that the lank">mercury-free catalyst has excellent catalytic performances for lank">acetylene hydrochlorination.
