but the acid site-driven C-C cleavage step is relatively sluggish in conventional bifunctional catalysts, 加氢裂化催化是塑料垃圾改性的关键途径,值得注意的是,确定超晶格中占据的Ce物种为实际活性位点, dramatically effecting the overall efficiency. We demonstrate here a facile and efficient way to boost the reactivity of acid sites by introducing Ce promoters into Pt/HY catalysts, Hongjie Zhang IssueVolume: 2024-01-06 Abstract: Hydrocracking catalysis is a key route to plastic waste upgrading。
通过对结构-性能关系的多次实验研究,但在传统的双功能催化剂中, the Ce species occupied in the supercage are identified as the actual active sites, 100 % of LDPE can be converted with 80.9 % selectivity of liquid fuels over the obtained Pt/5Ce-HY catalysts at 300 C in 2 h. For comparison,imToken官网下载,研究人员展示了一种简单有效的方法。
其对短链中间体的吸附能力显著提高,从而实现更好的金属酸平衡,相关研究成果发表在2024年1月6日出版的《德国应用化学》,imToken,与获得的Pt/5Ce-HY催化剂相比。
