摘要： The instant invention relates to a reactor useful in upgrading heavy oils admixed with a catalyst composition in a slurry. The liquid recirculating reactor of this invention employs a dispersed bubble flow regime, which requires a high liquid to gas ratio. A dispersed bubble flow regime results in more even flow patterns, increasing the amount of liquid that can be upgraded in a single reactor.

摘要： A new residuum full hydroconversion slurry reactor system has been developed that allows the catalyst, unconverted oil and converted oil to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is partially separated in between the reactors to remov e only the converted oil while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor where a portion of the unconverted oil is converted to lower boiling point hydrocarbons, once again creating a mixture of unconverted oil, converted oil, and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. The oil may alternately be partially converted, leaving a highly concentrated catalyst in unconverted oil which can be recycled direct ly to the first reactor. Fully converted oil can be subsequently hydrofinished for the nearly complete removal of hetoroatoms such as sulfur and nitrogen.

摘要： Systems and methods for hydroprocessing a heavy oil feedstock with reduced heavy oil deposits, the system employs a plurality of contacting zones and separation zones zone under hydrocracking conditions to convert at least a portion of the heavy oil feedstock to lower boiling hydrocarbons, forming upgraded products, wherein water and / or steam being optionally injected into first contacting zone in an amount of 1 to 25 weight % on the weight of the heavy oil feedstock. In one embodiment, the first contacting zone is operated at a temperature of at least 10°F. lower than a next contacting zone. The contacting zones operate under hydrocracking conditions, employing a slurry catalyst for upgrading the heavy oil feedstock, forming upgraded products of lower boiling hydrocarbons. In the separation zones, upgraded products are removed overhead and optionally, further treated in an in-line hydrotreater. At least a portion of the non-volatile fractions recovered from at least one of the separation zones is recycled back to the first contacting zone in the system, in an amount ranging between 3 to 50 wt. % of the heavy oil feedstock. In one embodiment, at least some of the heavy oil feedstock is supplied to at least a contacting zone other than the first contacting zone and / or at least some of the fresh slurry catalyst is supplied to at least a contacting zone other than the first contacting zone. In one embodiment, at least a portion of the non-volatile fractions recovered from at least one of the separation zones is sent to the interstage solvent deasphalting unit, for separating unconverted heavy oil feedstock into deasphalted oil and asphaltenes. The deasphalted oil stream is sent to one of the contacting zones for further upgrade.

摘要： Applicants have developed a new residuum full hydroconversion slurry reactor system that allows the catalyst, unconverted oil and converted oil to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is partially separated in between the reactors to remove only the products and hydrogen gas, while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor. A portion of the unconverted oil is then converted to lower boiling point hydrocarbons, once again creating a mixture of unconverted oil, products, hydrogen, and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. Additional oil may be added at the interstage feed inlet, possibly in combination with slurry. The oil may alternately be partially converted, leaving a highly concentrated catalyst in unconverted oil which can be recycled directly to the first reactor.

摘要： Se describe un proceso de una pasada flexible para hidroprocesar materia prima de aceite pesado. El proceso emplea una pluralidad de zonas de contacto y al menos una zona de separación para convertir al menos una porción de la materia prima de aceite pesado en hidrocarburos en ebullición inferiores, formando productos enriquecidos. Las zonas de contacto operan bajo condiciones de hidrocraqueo, utilizando un catalizador de lechada que comprende un catalizador de metal activo que tiene un tamaño de partícula promedio de al menos 1 micra en un diluyente de aceite hidrocarbonado, a una concentración mayor de 500 wppm del catalizador de metal activo para la materia prima de aceite pesado. La pluralidad de zonas de contacto y de zonas de separación se configura en una forma permutable que permite que el proceso de una pasada sea flexible operando en varios modos: un modo secuencial; un modo paralelo; una combinación del modo paralelo y secuencial; todos en línea; algunos en línea y algunos en espera; algunos en línea y algunos fuera de línea; un modo paralelo con la corriente efluente de la zona de contacto siendo enviada a por lo menos una zona de separación en serie con la zona de contacto; un modo paralelo con la corriente efluente de la zona de contacto estando combinada con una corriente efluente de la menos otra zona de contacto y enviada a la zona de separación; y sus combinaciones. En una modalidad, el efluente de una zona de contacto se envía al a siguiente zona de contacto en serie para enriquecimiento adicional, con la siguiente zona de contacto que tiene una caída de presión de cuando mucho 7.03 kg/cm2 (100 psi), la caída de presión no se debe a un dispositivo reductor de presión como en la técnica anterior. En una modalidad, se agrega al menos un material aditivo seleccionado de aditivos inhibidores, agentes antiespumantes, estabilizadores, depuradores de metal, removedores de contaminantes de metal, pasivadores de metal, y materiales de sacrificio, en una cantidad de menos de 1% en peso de la materia prima de aceite pesado, a por lo menos una de las zonas de contacto.
