Abstract

Active carbon used for the preparation of BaCl₂/AC catalyst was pretreated by different acid/base solutions, and the effect of different pretreatment oncatalytic performance was studied. The results showed that the catalyst derived from active carbon pretreated by 0.1 mol/L ammonia solution was the best one (BaCl₂/AC-A(0.1)). Comparing with BaCl₂/AC-F, derived from non-pretreated active carbon, the tetrachloroethane conversion over BaCl₂/AC-A(0.1) raised by 6.88%, trichloroethylene selectivity and yield increased 2.57% and 8.46%, respectively. The results of stability test showed that ammonia solution pretreatment could improve catalytic activity and stability, and the supported BaCl₂ could improve catalytic activity. Under the same optimal conditions, the conversion of tetrachloroethane over BaCl₂/AC-A (0.1) was 5% higher than that of the industry catalyst with similar trichloroethylene selectivity.
