摘要

绿色交易 "目标以及不断收紧的排放法规促进了对替代推进系统的研究。在非道路移动机械(NRMM)领域,这些努力主要围绕可持续燃料展开,同时保持较高的能源安全(多种燃料)效益。在这种情况下,氢化植物油(HVO)和甲醇(MEOH)的混合物是最有前途但研究不足的替代品之一,因此需要专门的方法来确定它们在发动机应用中的适用性。在本文中,我们评估了傅立叶变换红外(FTIR)分析法在确定 MEOH-HVO 混合物稳定性方面的可行性。研究考虑了储存过程中的温度影响,将测试样品分别置于 -20 °C 和 +20 °C 温度条件下。六周后对混合物和不同助溶剂的稳定性进行分析,并利用傅立叶变换红外光谱确定化学键。通过傅立叶变换红外光谱分析,MEOH20 与 1-十二醇混合可产生稳定的均质烷基醚燃料,而 MEOH20 与丁酸甲酯混合可产生酯燃料。根据贮存温度的不同,混合样品也存在明显的差异。总之,两种燃料混合物样品形成了不同类型的燃料,它们在室温下稳定且均质,为它们在不同类型的非催化还原媒介中的应用提供了巨大潜力。

FTIR Analysis for Determining Stability of Methanol–HVO Blends for Non-Road Engine Application
The Green Deal targets, along with tightening emissions legislation, foster research on alternative propulsion systems. In non-road mobile machinery (NRMM), these efforts largely rally around sustainable fuels while keeping the benefits of energy security (multi-fueling) high. In this context, the blends of Hydrogenated Vegetable Oil (HVO) and Methanol (MEOH) are amongst the most promising yet under-researched alternatives and, as such, need dedicated methods for determining their suitability in engine applications. In this paper, we evaluate the feasibility of Fourier transform infrared (FTIR) analytics for determining the stability of MEOH-HVO mixtures. The research considers temperature effects during storage by conditioning the test samples at −20 °C and +20 °C. The stability of the blends and different co-solvents is analysed after six weeks, and FTIR spectra are used to identify the chemical bonds. From FTIR analysis, blending MEOH20 with 1-dodecanol results in stable homogenous alkyl-ether fuels, while the MEOH20 blend with methyl-butyrate results in ester fuels. There are observable differences in the blend samples according to their storage temperatures. In conclusion, both fuel blend samples formed different fuel types, which are stable and homogenous at room temperature, posing great potential for their applicability in different NRMM types.
