Systems and methods for producing a crude product are described herein. Systems include an upstream contacting zone and a downstream contacting zone coupled to the upstream contacting zone. The upstream contacting zone and the downstream contacting zone include one or more catalysts. Contact of a hydrocarbon feed with the one or more of the catalysts produces a hydrocarbon feed/total product mixture having a molybdenum content of at most 90% of the molybdenum of the hydrocarbon feed. Contact of the hydrocarbon feed/total product mixture in downstream with one or more downstream catalysts produces a crude product having a molybdenum content of at most 90% of the molybdenum content of the hydrocarbon feed and at most 90% of the residue content of the hydrocarbon feed. Methods of producing a crude product using said systems are described herein. Compositions of said crude product produced from said systems and methods are described herein. |
