Abstract: Methods are provided for determining the compatibility of various grades of fuel oils, as well as methods for modifying fuel oils to improve compatibility and improved compatibility compositions. It has been discovered that the toluene equivalent solvation power of a blend of fuel oils does not vary in a straightforward manner with respect to the toluene equivalent solvation power of the individual blend components. Instead, it has been determined that the asphaltene content of the individual components can also influence the toluene equivalent solvation power of the final blend. Based on this discovery, methods are provided that can allow for modification of one or more components of a potential fuel oil blend. This can reduce and/or minimize the likelihood of asphaltene precipitation when a fuel oil blend is formed.
Abstract translation: 提供了用于确定各种等级的燃料油的相容性的方法，以及用于改进燃料油以改善相容性和改进的相容性组合物的方法。 已经发现燃料油混合物的甲苯当量溶剂化能力相对于各个共混组分的甲苯当量溶剂化能力来说并不是简单的变化。 相反，已经确定单个组分的沥青质含量也可以影响最终共混物的甲苯当量溶剂化能力。 基于这一发现，提供了可以允许修改潜在燃料油共混物的一种或多种组分的方法。 当形成燃料油共混物时，这可以减少和/或最小化沥青质沉淀的可能性。
