摘要

与石油碳氢化合物的残余组分相比，来自化学废物的裂解油残渣（沸腾温度超过360°C）是一种未被开发的原料。在炼油厂通过裂解技术进行协同加工时，需要解决的主要问题是与石油碳氢化合物的相容性。从多种推荐的方法中，采用SARA分组分析、标准和数字化现场试验、光学显微镜相结合的方法，在0 ~ 100 wt%的浓度范围内，对加氢裂化和催化裂化标准进料与废轮胎和废塑料热解油蒸馏渣油的均匀性和相容性进行了评价。共评估了40个样本。研究表明，这些共混物的性能很难预测，因为它高度依赖于特定的共混物和所含组分的浓度。值得注意的是，最显著的相容性问题是在一种饲料与另一种饲料的低浓度下观察到的——这是对热解油渣协同处理的关键见解。总体而言，加氢裂化料与废塑料热解油渣、催化裂化料与废轮胎热解油渣的配合比最佳。

Compatibility of feed for hydrocracking and FCC with scrap tires and waste plastics pyrolysis oil residue

In contrast to residual fractions of petroleum hydrocarbons, pyrolysis oil residues (boiling above 360 °C) from chemical waste represent an underexplored feedstock. The primary issue that will need to be addressed in their coprocessing in oil refineries by cracking technologies will be compatibility with petroleum hydrocarbons. From a variety of recommended methods, a combination of SARA group analysis, standard and digitized spot test, and optical microscopy were used to evaluate the homogeneity and compatibility of standard feed for hydrocracking and FCC with scrap tires and waste plastics pyrolysis oil distillation residue in the concentration range of 0–100 wt%. A total of 40 samples were evaluated. It has been shown that the behavior of these blends is difficult to predict, as it is highly dependent on the particular blend and the concentration of the components contained. Notably, the most significant compatibility issues were observed at low concentrations of one feed in the other—a critical insight for the coprocessing of pyrolysis oil residues. Overall, blending hydrocracking feed with waste plastics pyrolysis oil residue, and FCC feed with scrap tires pyrolysis oil residue, showed the most favorable compatibility profiles.
