In particular, a straw-based Ablative Fast Pyrolysis (AFP) oil was upgraded via hydrotreatment (HDT) in order to be used as a blending component with fossil-based intermediates. The raw pyrolysis oil is characterized by H/C = 0.14, O/C = 0.58 and C = 57.73 wt%, while the HDT pyrolysis oil has a H/C = 0.14, O/C = 0.016 and C = 85.85 wt%. Based on the density, viscosity and composition, and in association with a typical refinery, the possible petroleum refinery entry points for HDT pyrolysis oil include Straight Run Gas-Oil (SRGO), Atmospheric Gas-oil (GO), Fluid Catalytic Cracking Light Cycle Oil (LCO) and Heavy Cycle Oil (HCO), as well as Light Vacuum Gas-Oil (LVGO). To that aim, this work examined raw and HDT bio-oil blends with the aforementioned candidate petroleum streams at a 30:70 v/v ratio (raw or HDT bio-oil/petroleum stream) with respect to their miscibility, by comparing the blend components’ properties, microscopic observation, and interfacial tension analysis. From the microscopic observation, the addition of HDT pyrolysis oil in all examined petroleum candidates renders a homogeneous mixture where the two phases cannot be distinguished. In addition, no interfacial tension was observed in the examined blends, while the blend of HDT pyrolysis oil with the different petroleum streams not only did not deteriorate the fuel characteristics over the original petroleum stream, but also it improved them, in some cases. In general, the HDT pyrolysis oil was found to be miscible with all the examined refinery streams, extending the potential further investigation of stabilized pyrolysis oil integration over oil refineries.

特别是，一种秸秆基烧蚀快速热解 (AFP) 油通过加氢处理 (HDT) 进行了升级，以用作与化石基中间体的混合组分。粗热解油的特征是 H/C = 0.14、O/C = 0.58 和 C = 57.73 wt%，而 HDT 热解油的 H/C = 0.14、O/C = 0.016 和 C = 85.85 wt%。根据密度、粘度和成分，并结合典型的炼油厂，HDT 热解油可能的炼油厂入口点包括直馏瓦斯油 (SRGO)、常压瓦斯油 (GO)、流化催化裂化轻循环油 (LCO) 和重循环油 (HCO)，以及轻真空瓦斯油 (LVGO)。为此，这项工作检查了原始和 HDT 生物油混合物与上述候选石油流的 30：通过比较混合组分的特性、显微镜观察和界面张力分析，70 v/v 比率（原始或 HDT 生物油/石油流）的混溶性。从显微镜观察，在所有检测的石油候选物中添加 HDT 热解油会产生均匀的混合物，其中两相无法区分。此外，在测试的混合物中没有观察到界面张力，而 HDT 热解油与不同石油流的混合物不仅没有使燃料特性比原始石油流劣化，而且在某些情况下还改善了它们。一般而言，发现 HDT 热解油与所有检查的炼油厂物流可混溶，扩大了对炼油厂稳定热解油整合的进一步研究的潜力。
