Heavy Oils Having Reduced Total Acid Number and Olefin Content |
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. |

1. A process for treating a heavy oil, comprising:
(a) heating a feedstock comprising a heavy oil to remove from said heavy oil a first fraction, wherein said first fraction contains no more than 25% of the total number of acid groups of the heavy oil, and thereby providing a second fraction, wherein said second fraction contains at least 75% of the total number of acid groups of the heavy oil; and (b) treating said second fraction under conditions that provide a treated heavy oil that has a total acid number (TAN) that does not exceed 1.0 mg KOH/g, or is at least 50% lower than the total acid number (TAN) of said heavy oil prior to step (a), an olefin content that does not exceed 1.0 wt. %, and a p-value which is at least 50% of the p-value of said heavy oil prior to step (a), or a p-value of at least 1.5. |
