摘要：
A process for treating a heavy oil by heating a feedstock comprising a heavy oil in order to separate from the heavy oil a first fraction. The first fraction contains no more than 25% of the total number of acid groups of the heavy oil. A second fraction contains at least 75% of the total number of acid groups of the heavy oil. The second fraction then is treated under conditions that provide a heavy oil that has a total acid number, or TAN, that does not exceed 1.0 mg KOH/g, or is at least 50% lower than the total acid number prior to treatment, an olefin content that does not exceed 1.0 wt. %, and a p-value of at least 50% of the p-value of the heavy oil prior to treatment, or a p-value that is at least 1.5.
