HYBRID REACTOR HEAVY PRODUCT UPGRADING METHOD WITH DISPERSED CATALYST UPTAKE

摘要

The invention thus relates to a method for hydrotreating a heavy petroleum load in at least one reactor containing a fixed-bed catalyst in which method a solution containing a dispersed catalyst or a dispersed catalyst precursor is continuously introduced into said reactor the particle size of said dispersed catalyst being between 1 nm and 100 µm. Specifically the invention relates to in situ catalyst formation for a method for hydrotreatment on the basis of a fixed-bed catalyst that picks up a dispersed catalyst on the solid support thereof.
