  • Publication number: 20140110307
    Abstract: An improved hydrocarbon cracking process includes a first reactor such as a nozzle reactor positioned in series with a second reactor such as a tubular reactor. A cracking fluid such as steam or natural gas is reacted with heavy hydrocarbon material in the first reactor. The first reactor may provide a tremendous amount of thermal and kinetic energy that initiates cracking of heavy hydrocarbon materials. The second reactor provides sufficient residence time at high temperature to increase the conversion of heavy hydrocarbon materials to the desired level. The cracking fluid functions as a hydrogen donor in the cracking reactions so that very little of the heavy hydrocarbon material becomes hydrogen depleted and forms coke even if the heavy hydrocarbon material is repeatedly recycled through the process.

  • Patent number: 7708877
    Abstract: 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 remove 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 directly to the first reactor. Fully converted oil is subsequently hydrofinished for the nearly complete removal of hetoroatoms such as sulfur and nitrogen.

  • Patent number: 7704379
    Abstract: The present invention relates to a process for converting Fischer-Tropsch wax to high quality lube basestocks using a molecular sieve Beta catalyst followed by a unidimensional intermediate pore molecular sieve with near circular pore structures having an average diameter of 0.50 nm to 0.65 nm wherein the difference between the maximum diameter and the minimum is ?0.05 nm. Both catalysts comprise one or more Group VIII metals. For example, a cascaded two-bed catalyst system consisting of a first bed Pt/Beta catalyst followed by a second bed Pt/ZSM-48 catalyst is highly selective for wax isomerization and lube hydrodewaxing with minimal gas formation.

  • Publication number: 20100018895
    Abstract: The present invention relates to a process for the selective conversion of hydrocarbon feed having a Conradson Carbon Residue content of 0 to 6 wt %, based on the hydrocarbon feed. The hydrocarbon feed is treated in a two-step process. The first is thermal conversion and the second is catalytic cracking of the products of the thermal conversion. The present invention results in a process for increasing the distillate production from a hydrocarbon feedstream for a fluid catalytic cracking unit. The resulting product slate from the present invention can be further varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step.

  • Patent number: 7591940
    Abstract: A catalytic hydrocracking process for the production of ultra low sulfur diesel wherein a hydrocarbonaceous feedstock is hydrocracked at elevated temperature and pressure to obtain conversion to diesel boiling range hydrocarbons. The resulting hydrocracking zone effluent is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the hydrocracking zone to produce a first gaseous hydrocarbonaceous stream and a first liquid hydrocarbonaceous stream. The first gaseous hydrocarbonaceous stream containing diesel boiling range hydrocarbons is introduced into a desulfurization zone and subsequently partially condensed to produce a hydrogen-rich gaseous stream and a second liquid hydrocarbonaceous stream containing diesel boiling range hydrocarbons. At least a portion of the first liquid stream is thermal cracked to produce diesel boiling range hydrocarbons. An ultra low sulfur diesel product stream is recovered.
