This project investigates the reasons behind why some coals become fluid at high temperatures and apply these findings to biomass. This fluid phase (metaplast) represents the main area of uncertainty in pyolysis. This project builds on current research into coal macerals (the constituents of coal) using specifically developed novel thermal techniques to capture the dynamic behaviour of the fluid phase during its transformation. Critically, these techniques offer a new method of characterising tar compounds and in particular the extracted components of the metaplast. It will provide fundamental insight into an area governed by "black art" and empiricism, guide renewable fuel substitution and optimise Australia's coal and biomass reserves.

该项目调查了一些煤在高温下变成流体的原因，并将这些发现应用于生物质。这种流体相（元质体）代表了溶解的主要不确定区域。该项目建立在目前对煤显微物（煤的成分）的研究基础上，使用专门开发的新型热技术来捕捉流体相变过程中的动态行为。至关重要的是，这些技术提供了表征焦油化合物的新方法，特别是提取的元质体成分。它将为“黑艺术”和经验主义统治的领域提供基本见解，指导可再生燃料替代，优化澳大利亚的煤炭和生物质储备。
