摘要: Ni(Co)Mo(W)/Al2O3催化剂是工业中最常用的加氢处理催化剂。磷作为Ni(Co)Mo(W)/Al2O3加氢处理催化剂中较为常用的添加剂,用于改善催化剂的物理化学性质。本文从磷对Ni(Co)Mo(W)/Al2O3加氢催化剂孔结构、酸性、活性组分分散度等理化性能以及磷对加氢脱硫(HDS)和加氢脱氮(HDN)催化性能两个方面的影响对文献研究结果进行了综述,对磷添加剂的研究结果、存在的分歧以及研究机会进行了分析讨论。

Abstract: Ni(Co) promoted molybdenum catalysts supported on γ-Al2O3 are the most widely used for hydrotreatment of oil fractions. Phosphorus is classified as a second promoter in Ni(Co)Mo/Al2O3 hydrotreating catalysts in order to improve some particular physicochemical properties of these catalysts. The influence of phosphorus on pore structure and acidity of catalysts,dispersions of activated metals,and hydrodesulfurization (HDS) and hydrodenitrification (HDN) performance of catalysts are discussed in this review. The finding of phosphorus additive,disagreement of conclusions of researchers,and future research and development sre analyzed.
