This invention relates to a process for determining the suitability of pyrolysis tar, such as steam cracker tar, for upgrading using hydroprocessing without excessive fouling of the hydroprocessing reactor. A pyrolysis tar is sampled, the sample is analyzed to determine one or more characteristics of the tar related to tar reactivity, and the analysis is used to determine conditions under which the tar can be blended, pre-treated, and/or hydroprocessed. 本发明涉及一种确定热解焦油例如蒸汽裂解器焦油对于提质加工使用加氢处理，而无加氢处理反应器过度结垢的适应性的方法。将热解焦油取样，将该样品分析来确定与该焦油的焦油反应性相关的一种或多种特性，并且使用该分析来确定该焦油可以在其下共混、预处理和/或加氢处理的条件。
