Abstract
Contact of a crude feed with two or more catalysts produces a total product that include a crude product. The crude feed has a total acid number of at least 0.1. The crude product is a liquid mixture at 25 ° C. and 0.101 MPa. The crude product has a total acid number of at most 90% of the total acid number of the crude feed. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.
Claims20
A method of producing a crude product, comprising:
- contacting a crude feed with one or more catalysts at a first temperature followed by contacting at a second temperature to produce a total product that includes the crude product, wherein the crude product is a liquid mixture at 25 ° C. at 0.101 MPa, the crude feed having a TAN of at least 0.3 and the crude feed having a C5 asphaltenes content of at least 0.04 grams of C5 asphaltenes per gram of crude feed;
- and
- controlling contacting conditions such that the first contacting temperature is at least 30 ° C. lower than the second contacting temperature, and the crude product has a TAN of at most 90% relative to the TAN of the crude feed, wherein TAN is as determined by ASTM Method D664 and the C5 asphaltenes content in the crude product is reduced relative to the C5 asphaltenes content of the crude feed as determined by ASTM Method D2007.
