Patent ID: 8070936

Claim:
A method of producing a crude product, comprising: contacting a crude feed with a hydrogen source in the presence of one or more catalysts to produce a total product that includes the crude product, wherein the crude product is a liquid mixture at 25Â° C. and 0.101 MPa, at least one of the catalysts comprising one or more transition metal sulfides, and the crude feed having a residue content of at least 0.2 grams of residue per gram of crude feed, as determined by ASTM Method D5307, and a weight ratio of atomic hydrogen to atomic carbon (H/C) in the crude feed is at least 1.5; and controlling contacting conditions such that the crude product has an H/C ratio of about 80 to about 120% of the H/C ratio of the crude feed, the crude product has a residue content of at most 10% of the residue content of the crude feed, as determined by ASTM Method D5307.
