Abstract The utilization of Liquefied Natural Gas (LNG) in the heavy-duty transport sector is a convenient and cost-effective step towards a sustainable future. However, there are questions regarding LNG fuel quality and destructive particles for engines. Basically nothing is known about particles in the commercial LNG being fueled today. The gravimetric and SEM-EDX results here demonstrates that there are precarious metal and silicon dioxide particles in fuel-grade LNG that can clog and erode engine parts. Considering these results further research in the direction of this study, including standardized method development, is highly motivated.

燃料级液化天然气中的颗粒

摘要 在重型运输部门使用液化天然气 (LNG) 是迈向可持续未来的便捷且具有成本效益的一步。然而，对于 LNG 燃料质量和发动机的破坏性颗粒存在问题。目前，人们对商业液化天然气中的颗粒基本上一无所知。此处的重量分析和 SEM-EDX 结果表明，燃料级 LNG 中存在不稳定的金属和二氧化硅颗粒，它们会堵塞和腐蚀发动机部件。考虑到这些结果，本研究方向的进一步研究，包括标准化方法开发，是非常积极的。
