摘要: 以活性炭为载体,SnCl4 为活性组分,添加不同含量的BiCl3 以及CoCl3,制备出了Sn@AC、Sn-Bi@ACSn-Bi-Co@AC系列乙炔氢氯化催化剂。运用XRD、物理吸附仪对催化剂微观结构进行了表征,并在常压固定床反应器上进行了乙炔氢氯化反应性能评价。研究发现,浸渍法合成的Sn-Bi-Co@AC催化剂中,SnCl4 负载量为
0%,BiCl3 负载量为5%,CoCl3 负载量为10%时,催化剂性能最优,乙炔转化率和氯乙烯的选择性可分别维持在90%和95%以上长达100h。通过对比三组催化剂失活前后织构性质数据的变化,发现Sn-Bi-Co@AC复合催化剂在失活后比表面积和孔容变化最小,这表明BiCl3 和CoCl3 的加入可以有效降低反应过程中催化剂表面积碳的产生,从而提高了催化剂的寿命。

Abstract: Using active carbon as carrier, SnCl4 based non mercury catalysts, including Sn@AC, Sn-Bi@AC, Sn-Bi-Co@AC, were synthesized by adding different content of BiCl3 and CoCl3. The catalysts were evaluated in acetylene hydrochlorination atmospheric fixed bed reactor. The results showed that the catalytic properties of synthetic three component catalysts were optimal on the proportion of 10%SnCl4, 5%BiCl3 and 10%CoCl3. Acetylene's conversion rate was more than 90% and the selectivity of vinyl chloride was around 95% within the reaction time of 100 h. Through the XRD and physical adsorption instrument, catalyst microstructures were characterized. Coconut shell activated carbon's specific surface area and pore size was significant increased after nitric acid treatment; adding component BiCl3 and CoCl3 could make the coke phenomenon on catalytic surface weakened.
