Abstract

A series of additives based on Fe(III)-modified MFI, FAU, and FER zeolites were investigated with focus on their efficiency in reducing NO_x in cracking catalyst regeneration flue gases. The zeolite efficiency was found to depend on the zeolite framework type and the modification method. The Fe/MFI additives exhibited excellent performance. The additives prepared by ion exchange—and distinguished by uniform distribution of highly active metal ions (Fe³⁺)—reached a NO_x reduction efficiency of 45.4%.

Fe/MFI、Fe/FAU和Fe/FER沸石对裂化催化剂再生烟气中NOx的还原效率

研究了以Fe（III）改性MFI、FAU和FER沸石为基础的一系列添加剂，重点考察了它们对裂解催化剂再生烟气中NOx的还原效果。分子筛的效率与分子筛骨架类型和改性方法有关。Fe/MFI添加剂表现出优异的性能。采用离子交换法制备的添加剂，其特点是高活性金属离子（Fe3+）分布均匀，NOx还原效率为45.4%。

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
