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.
1. 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; andcontrolling contacting conditions such that the first contacting temperature is at least 30...
