  • Patent number: 8926825
    Abstract: Methods for removing sulfur from hydrocarbon streams using the sequential application of hydrodesulfurization, fractionation and oxidation. The hydrodesulfurization step is operative to remove easily-hydrogenated sulfur species, such as sulfides, disulfides and mercaptans. The resultant stream is then fractionated at a select temperature range to generate a sub-stream that is sulfur-rich with the sulfur species resistant to removal by hydrodesulfurization. The sub-stream is then isolated and subjected to an oxidative process operative to oxidize the sulfur species to sulfones or sulfoxides, which may then be removed by a variety of conventional methods, such as absorption. Alternatively, the methods may comprise using the sequential application of fractionation to generate a sulfur-rich sub-stream followed by oxidation and subsequent removal of the sulfur species present in the sub-fraction. The latter methods are ideally suited for transmix applications.

  • Patent number: 8900443
    Abstract: Methods for processing a hydrocarbonaceous feedstock flows are provided. In one embodiment, the method includes providing two or more hydroprocessing stages disposed in sequence, each hydroprocessing stage having a hydroprocessing reaction zone with a hydrogen requirement and each stage in fluid communication with the preceding stage. The hydrocarbonaceous feedstock flow may be separated into portions of fresh feed for each hydroprocessing stage, and the first portion of fresh feed to the first hydroprocessing stage is heated. The heated first portion of fresh feed may be supplied with hydrogen from the hydrogen source in an amount satisfying substantially all of the hydrogen requirements of the hydroprocessing stages to a first hydroprocessing zone. The unheated second portion of fresh feed is injected counter current to the process flow as quench at one or more locations in one or more of the reaction zones.

  • Patent number: 8894838
    Abstract: The present invention provides a process for hydroprocessing hydrocarbons with uneven catalyst volume distribution among two or more catalyst beds. The process operates as a liquid-full process, wherein all of the hydrogen dissolves in the liquid phase. Hydrocarbons can be converted in the process to provide a liquid product including clean fuels with multiple desired properties such as low density and high cetane number.

  • Publication number: 20140339132
    Abstract: A process for making high cetane diesel. The process includes contacting a distillate feedstock in a hydrodenitrogenation and polyaromatics saturation zone and passing the resulting treated effluent to a high pressure stripping zone. The stripped liquid fraction from the high pressure stripping zone is contacted with a base metal catalyst under monoaromatics saturation conditions to yield a reactor product. The reactor product undergoes a separation to provide a hydrogen portion and a dearomatized distillate portion with the hydrogen portion being recycled and introduced into the high pressure stripping zone.

    Abstract: This disclosure relates to liquid-full processes for hydroprocessing a light cycle oil (LCO). The processes involve hydrotreatment followed by selective ring opening in the presence of hydrotreating catalyst and selective ring opening catalyst respectively. The selective ring opening catalyst can be either zeolite ring opening catalyst or amorphous ring opening catalyst. In aspects of zeolite ring opening catalyst, the volume ratio of the total amount of the zeolite ring opening catalyst to the total amount of the hydrotreating catalyst is from about 0.2 to about 1.5. In aspects of amorphous ring opening catalyst, the volume ratio of the total amount of the amorphous ring opening catalyst to the total amount of the hydrotreating catalyst is from about 0.2 to about 3.

  • Patent number: 8864975
    Abstract: Integrated hydroprocessing methods using high activity, low density catalysts are provided. The high activity catalysts allow for lower temperature operation, which reduces catalyst degradation, while the low density of the catalysts means a corresponding reduction in the amount of metal needed to fill a reactor volume. The methods allow for flexible processing of feedstocks with a variety of wax contents.

  • Patent number: 8834706
    Abstract: The present invention relates to a method for preparing lubricating base oils by using vacuum distilled deasphalted oil, and more specifically, to a method for preparing various kinds of lubricating base oils by distilling a distillate obtained from a solvent deasphalting (SDA) process under reduced pressure to obtain heavy deasphalted oil (H-DAO) and light deasphalted (Lt-DAO) and then treating the H-DAO and the Lt-DAO by catalytic reactions, respectively. According to the present invention, it is possible to obtain heavy lubricating base oil (150BS) of a high viscosity grade which can not be obtained by a known catalytic reaction and a lubricating base oil of group III by hydrogenation, in a high yield, and thus economical efficiency is excellent.
