摘要

摘要本研究探讨了癸醛在沸石催化剂上的加氢脱环反应。研究综合使用了 TEM、SEM、低温氮吸附/解吸和 XPS 等物理化学方法对合成的催化剂进行了表征。研究发现，沸石结构对加氢脱环过程有重大影响。这一过程包括一个环的异构化，然后打开该环。在催化剂中加入铱可促进支链碳氢化合物的生产。在 300-400°C 的温度范围和 50 atm 的初始氢压下测试该过程时，Ir/BEA 催化剂表现出最高的活性：在 350°C 时，癸醛的脱环率超过 50%。

Hydrodecyclization of Naphthenes over Iridium-Containing Zeolite Catalysts

Abstract

The study investigates the hydrodecyclization of decalin over zeolite catalysts. The synthesized catalysts were characterized using a combination of physicochemical methods, such as TEM, SEM, low-temperature nitrogen adsorption/desorption, and XPS. The zeolite structure was found to have a major effect on the hydrodecyclization process. This process involves the isomerization of one ring followed by the opening of that ring. Incorporating iridium into the catalysts promoted the production of branched hydrocarbons. When testing the process in the temperature range of 300–400°C and at an initial hydrogen pressure of 50 atm, the Ir/BEA catalyst exhibited the highest activity: at 350°C the decyclization of decalin exceeded 50%.

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.
