生物质热解油有潜力用作燃料油替代品。燃烧测试表明，这些油在标准或稍加改造的锅炉和发动机中可以有效燃烧，其燃烧速率与商业燃料相似。然而，这些测试也发现了生物油应用中由于其特性而面临的一些挑战。这些油的热值仅为碳氢燃料的 40-50%。它们的含水量很高，不利于点燃。油中的有机酸会腐蚀普通建筑材料。固体（炭）会堵塞喷射器或腐蚀涡轮叶片。随着时间的推移，油中某些成分的反应性会导致形成较大的分子，从而导致高粘度和较慢的燃烧。本文讨论了与燃料应用相关的生物油的物理和化学特性以及改善这些特性的一些低成本方法。它还提供了一些工业用户提出的生物油规格以及储存和处理的建议。
Biomass pyrolysis oils have potential to be used as a fuel oil substitute. Combustion tests have shown that the oils burn efficiently in standard or slightly modified boilers and engines with rates similar to those for commercial fuels. However, these tests also identified several challenges in bio-oils applications resulting from their properties. The oils have heating values of only 40-50% of that for hydrocarbon fuels. They have a high water content that is detrimental for ignition. Organic acids in the oils are corrosive to common construction materials. Solids (char) can block injectors or erode turbine blades. Over time, reactivity of some components in the oils leads to formation of larger molecules that results in high viscosity and in slower combustion. This paper discusses physical and chemical characteristics of bio-oils relevant to fuel applications as well as some low-cost methods for improvement of these properties. It also provides bio-oil specifications proposed by some industrial users and recommendations for storage and handling.
