提质烃热解产物
摘要：
本发明涉及一种效用流体，例如含有芳族和非芳族环化分子的流体，其当加氢处理热解焦油，例如蒸汽裂化器焦油时，可以用作稀释剂。所规定的效用流体包含≥10.0wt％芳族和非芳族环化合物以及如下的每种物质：(a)≥1.0wt％的1.0环种类化合物；(b)≥5.0wt％的1.5环种类化合物；(c)≥5.0wt％的2.0环种类化合物；和(d)≤0.1wt％的5.0环种类化合物。本发明还涉及生产这样的效用流体的方法和加氢处理热解焦油的方法。
摘要（英）：

The invention relates to a utility fluid, such as a fluid containing aromatic and non- aromatic ringed molecules, useful as a diluent when hydroprocessing pyrolysis tar, such as steam cracker tar. The specified utility fluid comprises >= 10.0 wt% aromatic and non- aromatic ring compounds and each of the following: (a) >= 1.0 wt% of 1.0 ring class compounds; (b) >= 5.0 wt% of 1.5 ring class compounds; (c) >= 5.0 wt% of 2.0 ring class compounds; and (d) <= 0.1 wt% of 5.0 ring class compounds. The invention also relates to methods for producing such a utility fluid and to processes for hydroprocessing pyrolysis tar.
