HYBRID REACTOR HEAVY PRODUCT UPGRADING METHOD WITH DISPERSED CATALYST UPTAKE

摘要

The invention concerns a process for the hydrotreatment of a heavy oil feed in at least one reactor containing a fixed bed catalyst, in which a solution containing a dispersed catalyst or a precursor of a dispersed catalyst is continuously introduced into said reactor, the particle size of said dispersed catalyst being in the range 1 nm to 100 μm.;More particularly, the invention concerns the in situ formation of a catalyst for a hydrotreatment process starting from a fixed bed catalyst which captures a dispersed catalyst on its solid support.
