| 摘 要： | 介绍BC-239型苯酐催化剂在金陵石化公司化工一厂一套苯酐装置的应用情况。一年运行数据表明，该催化剂选择性平均值达1．090，进121催化剂选择性平均值1．093；在反应器盐温保持不变条件下，苯酐产品收率下降很慢，与同类进121催化剂基本相同，说明BC-239型催化剂的选择性和稳定性与进口催化剂接近，加上价格优势，具备了市场竞争力。

| Abstract: | The commercial application of BC - 239 catalyst in phthalic anhydride unit in No. 1 Chemical Plant was described. One - year operation showed that the average selectivity of BC - 239 and imported catalyst was 1.090 and 1.093 respectively. When keeping salt bath temperature in reactor unchanged, the yield of the product decreased very slowly, which was the same as the imported catalyst. Because of approximate selectivity and stability in addition to advantage in price, BC - 239 has competence in market. |
