Abstract:
1. An ebullated bed hydroprocessing system, comprising: an ebullated bed reactor comprised of: mixing apparatus for intimately mixing a catalyst precursor composition with a hydrocarbon oil diluent at a temperature below which the catalyst precursor composition decomposes in order to form a diluted precursor mixture comprised of the hydrocarbon oil diluent and the catalyst precursor composition; blending apparatus positioned upstream of the ebullated bed reactor for blending the diluted precursor mixture with the heavy oil feedstock to form a conditioned feedstock in which the catalyst precursor composition is sufficiently well dispersed within the heavy oil feedstock so as to form the colloidal or molecular catalyst in situ upon heating and decomposition of the catalyst precursor composition; and heating means for heating the conditioned feedstock in order to decompose the catalyst precursor composition and form the colloidal or molecular catalyst in situ within the heavy oil feedstock.
