摘要
本文综述了分子筛对加氢脱硫催化剂深度脱硫性能的影响,对分子筛基加氢脱硫催化剂上涉及含硫大分子4,6-二甲基二苯并噻吩(4,6-DMDBT)加氢脱硫反应的研究进展作了总结。主要介绍了微孔分子筛、介孔分子筛、微介孔复合分子筛和纳米分子筛在加氢脱硫催化剂针对4,6-DMDBT加氢脱硫反应方面的应用进展。简要介绍了分子筛基加氢脱硫催化剂上4,6-DMDBT加氢脱硫反应的反应途径、反应机理及抑制过度裂化反应的措施。最后展望了该研究领域的发展前景。
The recent progress in the application of zeolites in hydrodesulfurization catalysts for the deep desulfurization is reviewed in this paper, including microporous zeolite, mesoporous zeolite, micro-mesoporous zeolite and nano-zeolite. The reaction pathways and mechanisms of the hydrodesulfurization of 4,6-DMDBT and the measures to inhibit the overcracking reactions of desulfurization products over hydrodesulfurization catalysts containing zeolites are described briefly. Finally, challenges and prospects for further development of this field are presented.
