摘要: 通过对辽河稠油进行低温氧化模拟实验, 考察了不同体系氧化反应前后气相组成、 稠油组成及性质的
改变情况。结果表明: 稠油与空气发生的低温氧化反应属于吸氧反应, 催化氧化反应使气体中氧气含量下
降到 2.71%, 消耗了空气中 87% 的氧, 氧化使稠油酸值及黏度增大; 加水催化氧化使稠油中胶质含量降低
13.95%, 沥青质含量上升 4.81%, 胶质、 沥青质总含量降低, 重组分降解了 17.94%; 环烷酸盐催化剂体系对
稠油有良好的催化活性, 促进了稠油氧化和裂解; 水在稠油空气低温催化氧化过程中起到了促进重组分裂

Abstract: In the low-temperature oxidation simulation experiments of Liaohe heavy oil, the change of composition
and nature of gas and heavy oil before and after the oxidation reaction of different system is inspected. The results
demonstrate as follows: The low temperature oxidation reactions occurred between heavy oil and air is oxygen-
addition reactions, which decreases the oxygen content in the gas to 2.71%, consumes 87% of the oxygen in the air,
and increases the acid number and viscosity of heavy oil. Water promoted oxidation of heavy oil makes the resin
content decrease 13.95%, the asphaltene content increase 4.81%, the total resin and asphaltene content decrease,
and the heavy components degrade 17.94%. The naphthenate catalyst system has an excellent catalytic oxidation
activity, which promotes the oxidation and cracking of heavy oil. Water promotes heavy constituent crack in the
low temperature catalytic oxidation reactions occurred between heavy oil and air.

Key words: heavy oil, air injection, low temperature oxidation, catalytic oxidation, group composition30
