Conversion of propane or butanes from natural/shale gas into propene or butenes, which are indispensable for the synthesis of commodity chemicals, is an important environmentally friendly alternative to oil-based cracking processes. Herein, we critically analyse recent developments in the non-oxidative, oxidative, and CO-mediated dehydrogenation of propane and isobutane to the corresponding olefins over metal oxide catalysts. Particular attention is paid to (i) comparing the developed catalysts in terms of their application potential, (ii) structure-activity-selectivity relationships for tailored catalyst design, and (iii) reaction-engineering aspects for improving product selectivity and overall process efficiency. On this basis, possible directions for further research aimed at the development of inexpensive and environmentally friendly catalysts with industrially relevant performance were identified. In addition, we provide general information regarding catalyst preparation and characterization as well as some recommendations for carrying out non-oxidative and CO-mediated dehydrogenation reactions to ensure unambiguous comparison of catalysts developed in different studies.
将天然气/页岩气中的丙烷或丁烷转化为丙烯或丁烯,这对于合成商品化学品来说不可或缺,是一种重要的、对环境友好的替代石油基裂解工艺的方法。在此,我们批判性地分析了在金属氧化物催化剂上丙烷和异丁烷非氧化、氧化以及CO介导脱氢生成相应烯烃的最新进展。特别关注以下几点:(i)根据开发的催化剂的应用潜力进行比较;(ii)为定制催化剂设计建立结构-活性-选择性关系;(iii)改进产物选择性和整体工艺效率的反应工程方面。在此基础上,确定了旨在开发具有工业相关性能的廉价且环境友好型催化剂的进一步研究的可能方向。此外,我们提供了关于催化剂制备和表征的一般信息,以及一些进行非氧化和CO介导脱氢反应的建议,以确保不同研究中开发的催化剂能进行明确比较。
