摘要
摘要 研究了在 650-750°C 温度范围内乙烷与 CO2 的氧化脱氢过程中,碱性和酸性预处理 Sibunit 碳载体对 Fe-Cr/С 氧化物体系催化性能的影响。结果表明,碱性处理可促进布杜尔-贝尔反应的活跃发生,而酸性处理则会随着催化剂表面碳化程度的增加而略微提高乙烷的转化率。
The Influence of Pretreatment of Carbon Support on the Catalytic Activity of Fe–Cr Oxide Systems in the Oxidative Dehydrogenation of Ethane
The influence of alkaline and acid pretreatments of Sibunit carbon support on the catalytic properties of Fe–Cr/С oxide systems was studied for the process of oxidative dehydrogenation of ethane with CO2 in a temperature range of 650–750°C. It has been established that alkaline treatment promotes the active occurrence of the Boudoir–Bell reaction, while acid treatment slightly increases ethane conversion with greater carbonization of the catalyst surface.
期刊介绍:
The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
