Abstract

A catalyst that one or more metals from Column 5 of the Periodic Table and/or one or more compounds of one or more metals from Column 5 of the Periodic Table is described. The catalyst exhibits one or more bands in a range from 650 cm⁻¹ to 1000 cm⁻¹, as determined by Raman Spectroscopy. Methods of contacting a crude feed with hydrogen with the catalyst to produce a crude product with minimal hydrogen uptake are also described.
