近日，北京化工研究院自主研发的新型BHL催化剂在中科炼化道达尔ADL环管聚乙烯工艺装置成功完成首次工业应用试验，综合性能全面超越进口同类催化剂。

道达尔ADL工艺对催化剂性能要求高，此前均使用进口专利商催化剂。北化院针对道达尔ADL工艺，历时多年开发新型高性能钛系催化剂——BHL催化剂。试验过程中，中科炼化和北化院团队紧密合作，催化剂切换顺畅，生产过程平稳，以创纪录的16.5小时将各项产品参数调整合格。相对于进口催化剂，BHL催化剂活性提高10%~20%，氢调性能平稳，共聚性能提升10%以上，制得的聚合物颗粒形态良好、细粉更少，树脂产品达到优级标准。

BHL催化剂工业应用试验的成功，标志着北化院研发的催化剂技术在国内淤浆聚乙烯工艺领域实现全覆盖。下一步，北化院将与中科炼化进一步深化产销研用合作，提升树脂产品质量，开发新型树脂产品，助力中科炼化降本增效，实现高质量发展。

Recently, the new BHL catalyst independently developed by Beijing Research Institute of Chemical Industry successfully completed the first industrial application test in the ADL ring polyethylene process unit of Total Refining and Chemical Co., LTD., and its comprehensive performance comprehensively surpassed that of imported similar catalysts.

The Total ADL process has high requirements for catalyst performance and has previously used imported patented catalysts. For Total ADL process, BHL catalyst, a new type of high-performance titanium catalyst, has been developed for many years. During the test, the team of Zhongke Refining and Chemical and Beihua Institute worked closely together, the catalyst was switched smoothly, the production process was smooth, and the product parameters were adjusted in a record 16.5 hours. Compared with the imported catalyst, the activity of BHL catalyst is increased by 10%~20%, the hydrogen conditioning performance is stable, the copolymerization performance is increased by more than 10%, the polymer particles are in good shape, the fine powder is less, and the resin products reach the superior standard.

The success of the industrial application test of BHL catalyst indicates that the catalyst technology developed by Beihua Institute has achieved full coverage in the domestic slurry polyethylene process field. In the next step, Beihua Institute will further deepen the cooperation with Zhongke Refining and Chemical in production, marketing and research, improve the quality of resin products, develop new resin products, and help Zhongke Refining and Chemical reduce costs and increase efficiency to achieve high-quality development.
