中文摘要：
为了研发一种替代汞催化乙炔氢氯化的催化剂，采用等体积浸渍法制备了用于乙炔氢氯化反应的Bi-Cu/C催化剂，并用X射线衍射（XRD）、扫描电子显微镜（SEM）和BET等方法进行了表征。在反应温度170℃，乙炔体积空速30h-1，原料配比V（HCl）/V（C2H2）=1.05的条件下采用常压固定床反应器考察了催化剂的催化性能。结果表明，Bi-Cu /C催化剂活性组分在载体表面高度分散；反应20h，最佳配比BiCl3-CuCl2/C催化剂性不低于90%，选择性高于99%。在此催化剂中加入PO43-改性后，催化活性和稳定性有了明显提高，乙炔转化率大于97.7%，达到氯化汞催化乙炔氢氯化的活性，虽然稳定性低于氯化汞催化剂，但为研发乙炔氢氯化非汞催化剂提供了实验基础。
英文摘要：
To develop a catalyst to substitute mercuric chloride for hydrochlorination of acetylene, a series of Bi-Cu/C catalysts was prepared by equivalent-volume impregnation and characterized by XRD, SEM and BET. Under the reaction conditions of 170 ℃, C2H2 gas hourly space velocity of 30 h-1, feed volume ratio V（HCl）/V（C2H2）=1.05, the catalytic performance of Bi-Cu/C catalysts was investigated in a fixed bed reactor at atmospheric pressure. The results show that the active components of Bi-Cu /C catalyst is highly dispersed on the surface of the carrier; after 20 h reaction, the activity of the best BiCl3-CuCl2/C catalyst is above 70%, the selectivity is higher than 99%. After PO43- modification, the activity and stability is significantly improved, the acetylene conversion rate is close to 98%, which achieves the activity of mercuric chloride for hydrochlorination of acetylene. Although the stability is not as good as mercuric chloride catalyst, it provides an experimental basis for further research and development of non-mercury catalyst for acetylene hydrochlorination.
