In Canada there is a drive to augment aviation turbine fuel (jet fuel) production from petroleum with jet fuel production from renewable or waste materials. Jet fuel produced from feed material other than petroleum is called synthetic jet fuel. For kerosene produced from renewable or waste materials to qualify as blending components to produce synthetic jet fuel, it must meet the appropriate specifications for both jet fuel and the additional specification requirements for synthetic jet fuel. The oil produced from renewable or waste materials invariably requires further refining to meet those specifications. The extent to which further refining is required is not always clear, because the relationship between composition and bulk properties is not established for all key jet fuel properties. This study aims to develop a composition-based relationship for two of the key jet fuel properties: onset of freezing and low temperature viscosity. The reason for focusing on onset of freezing and cryogenic viscosity is because there are no reliable predictive methods available for those properties. Not knowing how composition affects these properties, makes it difficult to predict what boiling range of material in the broader kerosene fraction can be considered for inclusion in synthetic jet fuel. It also makes it difficult to devise appropriate refining strategies for converting oil from renewable and waste materials into on-specification blending components for synthetic jet fuel. The approach that will be followed is to experimentally measure onset of freezing and cryogenic viscosity for a variety of kerosene range mixtures and then relate those to composition in a way analogous to what was proposed by Cookson, Lloyd and Smith (Energy Fuels 1987, 1, 438-447) for petroleum-derived jet fuels. Two different types of kerosene range materials will be considered in this work: (i) model mixtures, and (ii) synthetic kerosenes, i.e. kerosene range material derived from processes for the conversion of renewable and/or waste materials. Model mixtures will be used to probe specific composition-property relationships. For example, to determine the change in properties as n-alkane to iso-alkane ratio (or cycloalkane ratio) is changed. In these instances the composition would be known and composition would be a manipulated variable. Synthetic kerosenes will be used to demonstrate that the composition-property relationships are robust, valid and can be applied to relevant to real kerosenes.

在加拿大，人们正在努力利用可再生材料或废弃材料生产喷气燃料，以增加从石油中生产航空涡轮燃料（喷气燃料）。由石油以外的原料生产的喷气燃料称为合成喷气燃料。对于由可再生材料或废料生产的煤油有资格作为生产合成喷气燃料的混合成分，它必须满足喷气燃料的适当规格和合成喷气燃料的附加规格要求。由可再生材料或废料生产的石油总是需要进一步精炼才能满足这些规格。需要进一步精炼的程度并不总是明确的，因为对于所有关键的喷气燃料特性，成分和整体特性之间的关系尚未建立。 本研究旨在为喷气燃料的两个关键特性建立基于成分的关系：冻结开始和低温粘度。关注冻结和低温粘度的原因是因为没有可靠的预测方法可用于这些特性。由于不知道成分如何影响这些特性，因此很难预测更广泛的煤油馏分中的材料的沸点范围可以考虑包含在合成喷气燃料中。它还使得难以设计适当的精炼策略，将可再生和废弃材料中的石油转化为合成喷气燃料的符合规格的混合成分。 接下来的方法是通过实验测量各种煤油范围混合物的冷冻和低温粘度的开始，然后以类似于 Cookson、Lloyd 和 Smith 提出的方式将这些与成分联系起来（Energy Fuels 1987, 1, 438-447）适用于石油衍生的喷气燃料。 本工作将考虑两种不同类型的煤油范围材料：(i) 模型混合物，和 (ii) 合成煤油，即源自可再生和/或废料转化过程的煤油范围材料。 模型混合物将用于探测特定的成分-性能关系。例如，为了确定当正烷烃与异烷烃的比率（或环烷烃比率）改变时性质的变化。在这些情况下，成分是已知的并且成分将是可操纵变量。将使用合成煤油来证明成分-性能关系是稳健的、有效的，并且可以应用于与真实煤油相关的情况。
