摘要： A fixed bed hydroprocessing system, and also a method for upgrading a pre-existing fixed bed hydroprocessing system, involves preliminarily upgrading a heavy oil feedstock in one or more slurry phase reactors using a colloidal or molecular catalyst and then further hydroprocessing the upgraded feedstock within one or more fixed bed reactors using a porous supported catalyst. The colloidal or molecular catalyst is formed by intimately mixing a catalyst precursor composition into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the precursor composition to form the colloidal or molecular catalyst in situ. Asphaltene or other hydrocarbon molecules otherwise too large to diffuse into the pores of the fixed bed catalyst can be upgraded by the colloidal or molecular catalyst. One or more slurry phase reactors may be built and positioned upstream from one or more fixed bed reactors of a pre-existing fixed bed system and/or converted from one or more pre-existing fixed bed reactors.

摘要： Methods and systems for hydroprocessing heavy oil feedstocks to form an upgraded material involve the use of a colloidal or molecular catalyst dispersed within a heavy oil feedstock, a hydrocracking reactor, and a hot separator. The colloidal or molecular catalyst promotes hydrocracking and other hydroprocessing reactions within the hydrocracking reactor. The catalyst is preferentially associated with asphaltenes within the heavy oil feedstock, which promotes upgrading reactions involving the asphaltenes rather than formation of coke precursors and sediment. The colloidal or molecular catalyst overcomes problems associated with porous supported catalysts in upgrading heavy oil feedstocks, particularly the inability of such catalysts to effectively process asphaltene molecules. The result is one or more of reduced equipment fouling, increased conversion level, and more efficient use of the supported catalyst if used in combination with the colloidal or molecular catalyst.

摘要： An ebullated bed hydroprocessing system, and also a method for upgrading a pre-existing ebullated bed hydroprocessing system, involves introducing a colloidal or molecular catalyst, or a precursor composition capable of forming the colloidal or molecular catalyst, into an ebullated bed reactor. The colloidal or molecular catalyst is formed by intimately mixing a catalyst precursor composition into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the precursor composition to form the colloidal or molecular catalyst in situ. The improved ebullated bed hydroprocessing system includes at least one ebullated bed reactor that employs both a porous supported catalyst and the colloidal or molecular catalyst to catalyze hydroprocessing reactions involving the feedstock and hydrogen. The colloidal or molecular catalyst provides catalyst in what would otherwise constitute catalyst free zones within the ebullated bed hydroprocessing system. Asphaltene or other hydrocarbon molecules too large to diffuse into the pores of the supported catalyst can be upgraded by the colloidal or molecular catalyst. A slurry phase reactor may be positioned upstream from one or more ebullated bed reactors or converted from a pre-existing ebullated bed reactor.

摘要： Methods and systems for mixing a catalyst precursor with a heavy oil feedstock preparatory to hydroprocessing the heavy oil feedstock in a reactor to form an upgraded feedstock. Achieving very good dispersion of the catalyst precursor facilitates and maximizes the advantages of the colloidal or molecular hydroprocessing catalyst. A catalyst precursor and a heavy oil feedstock having a viscosity greater than the viscosity of the catalyst precursor are provided. The catalyst precursor is pre-mixed with a hydrocarbon oil diluent, forming a diluted catalyst precursor. The diluted precursor is then mixed with at least a portion of the heavy oil feedstock so as to form a catalyst precursor-heavy oil feedstock mixture. Finally, the catalyst precursor-heavy oil feedstock mixture is mixed with any remainder of the heavy oil feedstock, resulting in the catalyst precursor being homogeneously dispersed on a colloidal and/or molecular level within the heavy oil feedstock.
