Abstract

Methods for conversion of a hydrocarbon feed to a total product are described. Contact of the hydrocarbon feed with one or more catalysts produces the total product. The total product includes a crude product that is a liquid mixture at 25° C. and 0.101 MPa and has a micro-carbon residue content of at most 90% of the micro-carbon residue content of the hydrocarbon feed.

Claims

1. A method of producing a crude product, comprising:

contacting a hydrocarbon 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 hydrocarbon feed has a micro-carbon residue (MCR) content of at least 0.0001 grams per gram of hydrocarbon feed; and

at least one of the catalysts has;

one or more metals from Column 6 of the Periodic Table and/or one or more compounds of one or more metals from Column 6 of the Periodic Table; and

one or more metals from Columns 9-10 of the Periodic Table and/or one or more compounds of one or more metals from Columns 9-10 of the Periodic Table; and

controlling contacting conditions at a partial pressure of hydrogen of at least 3 MPa and a temperature of at least 200°

C. to produce the crude product, the crude product having a MCR content of at most 90% of the MCR content of the hydrocarbon feed, wherein MCR content is as determined by ASTM Method D4530.
