Abstract

Hydrodeoxygenation (HDO) is one of the effective methods to upgrade biomass pyrolysis oil, but the development of a low-cost, high-performance HDO catalyst still faces enormous challenges. In this work, a facile and eco-friendly approach is developed to synthesize the NiP@hierarchical HZSM-5 catalyst. Structure and acidity of the catalyst can be controlled by simply adjusting the proportions of ammonia solution and the silicon to aluminum ratio, which are closely related to the performance of the catalyst. Experimental results reveal that the NiP@hierarchical HZSM-5 catalyst with Si/Al = 85 under NH·HO/Ni = 14 exhibits the highest activity of 98% guaiacol conversion, along with a 78.8% yield of cyclohexane (reaction conditions: 300 °C, 3 MPa H). In addition, the guaiacol reaction network is provided.

摘要

加氢脱氧（HDO）是升级生物质热解油的有效方法之一，但开发低成本、高性能的HDO催化剂仍面临巨大挑战。在这项工作中，开发了一种简便且环保的方法来合成NiP@分级HZSM-5催化剂。通过简单地调节氨溶液的比例和硅铝比可以控制催化剂的结构和酸度，而这两者与催化剂的性能密切相关。实验结果表明，在NH·HO/Ni = 14的条件下，Si/Al = 85的NiP@分级HZSM-5催化剂表现出最高活性，愈创木酚转化率达98%，同时环己烷产率为78.8%（反应条件：300℃，3MPa H）。此外，还给出了愈创木酚反应网络。
