Disclosed is an improved process for the hydrodemetallization, hydrodesulfurization, hydrodenitrogenation, and hydroconversion of a hydrocarbon feedstock containing asphaltenes, metals and Shell hot filtration solids precursors. The process utilizes a catalyst mixture wherein one component of the mixture is a relatively small pore catalyst and another component is a catalyst that possesses a relatively large amount of macropore volume.

A laboratory instrument provides a small model reactor which better simulates a back mixed reactor containing a catalyst. The reactor is especially valuable for simulating commercial scale hydrotreating of petroleum resid, coal, and other non-distillable hydrocarbons to obtain some distillable products. An important feature is a magnetically driven pump completely enclosed within the reactor shell of the simulator. All embodiments provide a high temperature and pressure, low liquid to catalyst volume, model reactor where an entire process is carried out within the simulator shell under substantially the conditions prevailing in the full scale reactor.
