Abstract

Oxymethylene ethers (OMEs) are currently being investigated as attractive substitutes for fossil diesel fuel. In particular, the properties of OMEs containing 3–5 formaldehyde units (CH3O(CH2O)nCH3 with n = 3–5) are similar and mostly compliant with current diesel specifications. With their production based on renewable methanol, OMEs can contribute significantly to a future sustainable mobility. This study elaborates an anhydrous, liquid phase OME synthesis based on dimethyl ether (DME). Using a newly designed continuous production plant, the performance of extruded zeolite catalysts based on a commercially available ZSM-5 material is evaluated. The characteristics of the produced catalysts are analyzed extensively and discussed. Comprehensive characterization of the spent catalyst as well as regeneration experiments were performed to investigate catalyst deactivation mechanisms. It was shown that deactivation mechanisms are similar to those observed in methanol-to-hydrocarbon processes. Thus, understanding of these aspects is improved and approaches for further optimization can be identified.

作为可持续柴油替代品的甲氧甲烷醚(OME)的生产:二甲醚和三氧烷的连续合成及催化剂稳定性评价
目前,人们正在研究甲氧基醚作为化石柴油的有吸引力的替代品。特别是,含有3-5个甲醛单位(n = 3-5的ch30 (CH2O)nCH3)的OMEs的性能相似,且大多符合现行柴油规范。凭借其基于可再生甲醇的生产,OMEs可以为未来的可持续交通做出重大贡献。本研究阐述了一种基于二甲醚(DME)的无水液相OME合成方法。在新设计的连续生产装置上,以市售ZSM-5为原料,对挤压型沸石催化剂的性能进行了评价。对所制催化剂的性能进行了广泛的分析和讨论。对废催化剂进行了综合表征,并进行了再生实验,探讨了催化剂失活机理。结果表明,失活机理与甲醇制烃过程相似。因此,可以提高对这些方面的理解,并确定进一步优化的方法。
