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，有一种从可再生材料或废料生产喷气燃料来增加从石油生产航空涡轮机燃料（喷气燃料）的动力。由石油以外的原料生产的喷气燃料称为合成喷气燃料。对于从可再生材料或废料生产的煤油，要作为生产合成喷气燃料的混合组分，它必须符合喷气燃料的适当规格和合成喷气燃料的附加规格要求。从可再生材料或废料生产的油总是需要进一步精炼，以满足这些规格。需要进一步精炼的程度并不总是清楚的，因为对于所有关键的喷气燃料性质，成分和本体性质之间的关系并不确定。 本研究的目的是开发一个基于组合物的关系的两个关键的喷气燃料的性能：开始冻结和低温粘度。之所以关注冻结和低温粘度的开始，是因为没有可靠的预测方法可用于这些性质。不知道组成如何影响这些性质，使得难以预测更广泛的煤油馏分中的材料的沸程可以考虑包含在合成喷气燃料中。这也使得难以设计适当的精炼策略，以将来自可再生材料和废料的油转化为用于合成喷气燃料的符合规格的共混组分。 将遵循的方法是实验性地测量各种煤油范围混合物的冻结起始和低温粘度，然后以类似于Cookson、Lloyd和Smith（Energy Fuels 1987，1，438-447）针对石油衍生的喷气燃料提出的方式将它们与组成相关联。 在这项工作中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，即从可再生和/或废料的转化过程中得到的煤油范围材料。 模型混合物将用于探测特定的组成-性质关系。例如，为了确定正烷烃与异烷烃的比率（或环烷烃比率）改变时的性质变化。在这些情况下，组成是已知的，组成是一个操纵变量。合成的煤油将被用来证明组成性质的关系是稳健的，有效的，可以应用到相关的真实的煤油。
