  • Patent number: 10407623
    Abstract: The disclosure describes a one-step liquid biphasic catalytic process for converting a carbohydrate-containing feedstock, preferably lignocellulose, to light naphtha (e.g., hexane, pentane, methyl cyclopentane, cyclohexane, etc.) in the presence of an acidic reactive aqueous phase and a redox catalyst in the organic extracting/reaction phase. The process provides a cost-effective route for producing light-naphtha components, in presence or not of deoxygenates. The light naphtha components are useful as feedstock for steam and catalytic cracking to produce value-added platform molecules like ethylene and propylene, as precursor for the synthesis of bioaromatics like benzene and as gasoline fuel feedstock, and as fuel additives (e.g., the concomitantly formed oxygenates) to improve the biological origin of carbon in the fuel.

  • Patent number: 10385283
    Abstract: Embodiments herein relate to a process flow scheme for the processing of gas oils and especially reactive gas oils produced by thermal cracking of residua using a split flow concept. The split flow concepts disclosed allow optimization of the hydrocracking reactor severities and thereby take advantage of the different reactivities of thermally cracked gas oils versus those of virgin gas oils. This results in a lower cost facility for producing base oils as well as diesel, kerosene and gasoline fuels while achieving high conversions and high catalyst lives.

  • Patent number: 10385281
    Abstract: Systems, methods and compositions for reducing the heteroatom content of hydrocarbon feed using transition metal complexes and adsorption techniques. The transition metal complexes include titanyl, hafnyl and zirconyl complexes activated using one or more hydroperoxides or peracids. The activated adsorbents are incorporated into one or more vessels as an adsorption bed for adsorbing the heteroatoms present in hydrocarbon feeds. The systems, methods and compositions separate the heteroatoms passed through the system by contacting the adsorption compositions with the heteroatoms of the hydrocarbon feed, adsorbing the heteroatom to the adsorption material, further allowing for the retrieval of a hydrocarbon product having a reduced heteroatom content.

  • Patent number: 10386018
    Abstract: The invention relates to injecting steam into crude oil for several benefits, primarily of which is to remove salt by transferring the salt into the condensed water from the steam. Steam transfers salt via a different transfer mechanism and therefore doesn't require the high shear mixing of conventional water injection systems. As such, steam injection through a variety of procedures, is more efficient at gathering salt into water that itself is easier to remove from the crude oil.

  • Patent number: 10351785
    Abstract: Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by with an apparatus arranged for flashing the feed at a target cut point temperature to obtain two fractions. A low boiling temperature fraction contains refractory, sterically hindered sulfur-containing compounds, which have a boiling point at or above the target cut point temperature. A high boiling temperature fraction, having a boiling point below the target cut point temperature, is substantially free of refractory sulfur-containing compounds. The high boiling temperature fraction is contacted with isomerization catalyst, and the isomerized effluent and the low boiling temperature fraction are combined and contacted with a hydrotreating catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level.

After mixed with hydrogen, catalyst and additive, oil-coal slurry is preheated into a slurry bed reactor with high reacting pressure for thermal cracking and hydrogenation reaction. After reaction, all the products go into the hot high pressure separator for separation of solid from the bottom and gas from the top. The gas obtained goes into the fixed bed reactor for further hydrocracking or refining, and the distillate obtained enter the fractionating tower. The vacuum gas oil from the bottom of fractionating tower is taken as recycle oil piped to the oil-coal slurry mixing device as solvent.
