  • Patent number: 8888991
    Abstract: Heavy gas oil components, coking process recycle, and heavier hydrocarbons in the delayed coking process are cracked in the coking vessel by injecting a catalytic additive into the vapors above the gas/liquid-solid interface in the coke drum during the coking cycle. The additive comprises cracking catalyst(s) and quenching agent(s), alone or in combination with seeding agent(s), excess reactant(s), carrier fluid(s), or any combination thereof to modify reaction kinetics to preferentially crack these components. The quenching effect of the additive can be effectively used to condense the highest boiling point compounds of the traditional recycle onto the catalyst(s), thereby focusing the catalyst exposure to these target reactants. Exemplary embodiments of the present invention can also provide methods to (1) reduce coke production, (2) reduce fuel gas production, and (3) increase liquids production.

  • Patent number: 8674153
    Abstract: A method for converting lignocellulosic biomass to a useful fuel is disclosed in a process sequence resulting in low levels of depositable tars in an output gas stream. One disclosed embodiment comprises performing a sequence of steps at elevated pressure and elevated hydrogen partial pressure, including fast (or flash) hydropyrolysis of a lignocellulosic biomass feed followed sequentially with catalytically enhanced reactions for the formation of methane operating at moderate temperatures of from about 400° C. to about 650° C. under moderately elevated pressure (about 5 atm to about 50 atm). A temperature rise in the catalyst above pyrolysis temperature is achieved without the addition of air or oxygen. Gas residence time at elevated temperature downstream of methane formation zones extends beyond the time required for methane formation. This sequence results in low tar deposit levels. The catalyst promotes preferential formation of methane and non-deposit forming hydrocarbons, and coke re-gasification.

    Abstract: A process for maximizing p-xylene production includes producing a naphtha fraction and a light cycle oil fraction from a fluid catalytic cracking zone. These fractions are combined and hydrotreated. Fractionation of the hydrotreated product makes a hydrocracker feed that is sent to a hydrocracking zone to make a naphtha cut and a hydrocracker product. The hydrocracker product is recycled back to the fractionation zone, and the naphtha cut is dehydrogenated in a dehydrogenation zone to make aromatics. Reforming catalyst from a catalyst regenerator moves downward through the dehydrogenation zone. Straight run naphtha and raffinate from the aromatics unit are introduced to an additional series of reforming zones. The reforming catalyst moves in parallel through the first reforming zone and the dehydrogenation zones, then is combined for entry to the second and subsequent reforming zones prior to regeneration.

  • Patent number: 6755962
    Abstract: A slurry phase reactor is designed to treat extra heavy petroleum crude in a combination of thermal-zone and catalytic-zone in a counterflow system where liquid feed is added to the top and hydrogen at the bottom. Feed enters the gas-phase thermal zone, where it passes to a liquid-phase thermal zone. In the liquid-phase thermal zone, the hydrocarbon is thermally cracked and the unreacted liquid is further passed to a catalytic-zone below in communication with the thermal-zone. Catalyst can be added or removed as required in a continuous mode without shutting down the system. The heat generated inside the catalytic cracking zone is distributed to the entire reactor as the gaseous product flows upward. Feed is brought to the reaction conditions by the heat recovered from the gas-phase zone. Reaction temperature could be controlled by feed temperature.

    Abstract: A slurry phase reactor is designed to treat extra heavy petroleum crude in a combination of thermal-zone and catalytic-zone in a counterflow system where liquid feed is added to the top and hydrogen at the bottom. Feed enters the gas-phase thermal zone, where it passes to a liquid-phase thermal zone. In the liquid-phase thermal zone, the hydrocarbon is thermally cracked and the unreacted liquid is further passed to a catalytic-zone below in communication with the thermal-zone. Catalyst can be added or removed as required in a continuous mode without shutting down the system. The heat generated inside the catalytic cracking zone is distributed to the entire reactor as the gaseous product flows upward. Feed is brought to the reaction conditions by the heat recovered from the gas-phase zone. Reaction temperature could be controlled by feed temperature.

  • Patent number: 6183627
    Abstract: Upgrading of a hydrocarbon feed containing sulfur, metals, and asphaltenes involves applying the feed to a distillation column for producing a substantially asphaltene-free, and metal-free distillate fraction and a non-distilled fraction containing sulfur, asphaltenes, and metals. At least some of the substantially asphaltene-free, and metal-free distillate fraction is converted to a hydrogen donor diluent. The non-distilled fraction is processed in a solvent deasphalting unit for producing a deasphalted oil stream and an asphaltene stream. After a combined stream is formed from the hydrogen donor diluent and the deasphalted oil stream, the combined stream is thermally cracked forming a thermally cracked stream that is applied to the distillation column.

  • Patent number: 5180868
    Abstract: The present invention is a multi-stepped method of converting an oil which is produced by various biomass and coal conversion processes and contains primarily single and multiple ring hydroxyaromatic hydrocarbon compounds to highly aromatic gasoline. The single and multiple ring hydroxyaromatic hydrocarbon compounds in a raw oil material are first deoxygenated to produce a deoxygenated oil material containing single and multiple ring aromatic compounds. Then, water is removed from the deoxygenated oil material. The next step is distillation to remove the single ring aromatic compouns as gasoline. In the third step, the multiple ring aromatics remaining in the deoxygenated oil material are cracked in the presence of hydrogen to produce a cracked oil material containing single ring aromatic compounds. Finally, the cracked oil material is then distilled to remove the single ring aromatics as gasoline.
