Patent ID: 7588681

Claim:
A method of producing a crude product, comprising: contacting a crude feed with one or more catalysts to produce a total product that includes the crude product, wherein the crude product is a liquid mixture at 25° C. and 0.101 MPa, the crude feed having a TAN of at least 0.3, and at least one of the catalysts is obtainable by: combining a support with one or more metals from Column 6 of the Periodic Table, one or more compounds of one or more metals from Column 6 of the Periodic Table, or mixtures thereof, to produce a catalyst precursor; and producing the catalyst by sulfiding the one or more Column 6 metals without converting the one or more Column 6 metals to metal oxides by heating the catalyst precursor in the presence of one or more sulfur containing compounds at a temperature below 500° C.; and wherein the one or more catalysts comprise in addition an additional catalyst, the additional catalyst having a pore size distribution with a median pore diameter of at least 60 Å, controlling contacting conditions such that the crude product has a TAN of at most 90% of the TAN of the crude feed.
