首先以蒽为化学探针对孤岛、辽河和胜利减压渣油及其四组分的氢转移能力进行表征，原理是，蒽与渣油在３５０～４００℃热反应，渣油向蒽供氢，使蒽转化成９，１０－二氢蒽，用气相色谱分析定量测定热反应产物中的９，１０－二氢蒽，并计算出单位重量油样供氢量；然后在４００℃下热处理测定三种渣油的生焦诱导期（定义为生焦０１％时所用时间）。结果发现：虽然它们四组分相近，但氢转移潜力相差较大，特别是它们的沥青质的氢转移能力相差悬殊；渣油热生焦诱导期长短与它们氢转移能力趋势一致
First anthracene as a chemical probe on island, Liaohe and Sheng Li vacuum residue and its four components of the hydrogen transfer ability of the principle is that anthracene and residue at 350 ~ 400 ℃ thermal reaction, the residue of hydrogen to anthracene , The anthracene is converted to 9,10-dihydroanthracene, and the 9,10-dihydroanthracene in the thermal reaction product is quantitatively determined by gas chromatographic analysis, and the amount of hydrogen per unit weight of the oil sample is calculated; then, heat treatment is performed at 400 ° C. Coke induction period of the three kinds of residual oil (defined as the time spent coke 0 1%). The results showed that although their four components were similar, the hydrogen transfer potential varied greatly, especially their asphaltene hydrogen transfer ability was quite different. The induction period of residual thermal enthalpy coincided with their hydrogen transfer ability
