Abstract: A hydrocracking system is upgraded by modifying an existing ebullated bed initially utilizing a supported ebullated bed catalyst to thereafter utilize a dual catalyst system that includes metal sulfide catalyst particles and supported ebullated bed catalyst. The upgraded hydrocracking system achieves at least one of: (1) hydroprocess lower quality heavy oil; (2) increase conversion of higher boiling hydrocarbons that boil at 524° C. (975° F.) or higher; (3) reduce the concentration of supported ebullated bed catalyst required to operate an ebullated bed reactor at a given conversion level; and/or (4) proportionally convert the asphaltene fraction in heavy oil at the same conversion level as the heavy oil as a whole. The metal sulfide catalyst may include colloidal or molecular catalyst particles less than 1 micron in size and formed in situ within the heavy oil using a catalyst precursor well-mixed within the heavy oil and decomposed to form catalyst particles.

Abstract: A hydrocracking system involves introducing a heavy oil feedstock and a colloidal or molecular catalyst, or a catalyst precursor capable of forming the colloidal or molecular catalyst, into a hydrocracking reactor. The colloidal or molecular catalyst is formed in situ within the heavy oil feedstock by 1) premixing the catalyst precursor with a hydrocarbon diluents to form a catalyst precursor mixture, 2) mixing the catalyst precursor mixture with the heavy oil feedstock, and 3) raising the temperature of the feedstock to above the decomposition temperature of the catalyst precursor to form the colloidal or molecular catalyst. The colloidal or molecular catalyst catalyzes upgrading reactions between the heavy oil feedstock and hydrogen and eliminates or reduces formation of coke precursors and sediment. The colloidal or molecular catalyst can be the sole or primary hydrocracking catalyst in a stand-alone hydrocracking reactor or it can be used together with a porous supported catalyst within a fixed bed or ebullated bed reactor.

Abstract: [Object]An object of the present invention is to produce a polyolefin by efficiently reusing unreacted monomers at low costs.[Solution to Problem]A polymerization apparatus 1 of the present invention includes: a liquid-phase reactor 2 in which olefin monomers are subjected to liquid-phase polymerization; a vapor-phase reactor 3 in which olefin monomers are subjected to vapor-phase polymerization; a condenser 4 that condenses unreacted olefin monomers discharged from the vapor-phase reactor 3 so as to produce a liquid containing the olefin monomers; and a liquefied monomer transfer line 11 through which the liquid containing the olefin monomers is transferred from the condenser 4 into the liquid-phase reactor 2. Thus, collected unreacted monomers can be directly subjected to the liquid-phase polymerization without additionally requiring a process such as purification steps. Therefore, the unreacted olefin monomers can be reused efficiently and economically.

Abstract: 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.
