Abstract
This invention provides a cobalt-containing catalyst precursor for the preparation of a catalyst for catalytic hydrotreatment of hydrocarbonaceous feedstocks, and for a method of making same.
Claims10
A process for making a Co-containing catalyst precursor comprising:
- providing a porous support;
- combining said support with a cobalt-containing compound, thereby forming a catalyst precursor having a volatile content;
- analyzing the catalyst precursor by Ultraviolet-visible (UV-vis) Electromagnetic Radiation;
- and,
- selecting the catalyst precursor having reflectance maxima between 460 nm and 500 nm and between 660 nm and 690 nm.
