  • Publication number: 20220169928
    Abstract: Systems and methods are provided for co-processing of biomass oil with mineral coker feeds in a coking environment. The coking can correspond to any convenient type of coking, such as delayed coking or fluidized coking. The biomass oil can correspond to biomass oil with a molar ratio of oxygen to carbon of 0.24 or less on a dry basis. Such types of biomass oil can be formed from pyrolysis methods such as hydrothermal pyrolysis, and are in contrast to biomass oils formed from pyrolysis methods such as fast pyrolysis. By using a biomass oil with a molar ratio of oxygen to carbon of 0.24 or less, improved yields of light coker gas oil can be achieved in conjunction with a reduction in the yield of heavy coker gas oil.

  • Publication number: 20220145189
    Abstract: Systems and methods are provided for processing a bio-derived feedstock in a commercial scale reactor to form renewable distillate boiling range fractions while managing the heat release. The management of the heat release is achieved in part by introducing 1.0 vol % or more of CO into at least a portion of the reaction environment for hydroprocessing of the bio-derived feedstock. The 1.0 vol % or more of CO can selectively reduce the activity of hydrotreating catalyst for olefin saturation.

  • Publication number: 20220145188
    Abstract: Systems and methods are provided for co-processing of biomass oil in a fluid catalytic cracking (FCC) system that include recovering an additional source of H2 or synthesis gas from the overhead product gas stream. The additional H2 can be used to partially hydrogenate biomass oil prior to co-processing the biomass oil in the fluid catalytic cracking system. Additionally or alternately, the additional synthesis gas can represent an additional yield of products from the process, such as an additional yield that can be used for synthesis of further liquid products.

  • Publication number: 20220072433
    Abstract: Disclosed are a display apparatus and a method for displaying a user interface. In response to a preset instruction, the display apparatus acquires local images to generate a local video stream, plays a local video picture, and displays a graphic element for identifying a preset expected position in a floating layer above the local video picture. When the moving target exists in the local video picture and an offset of a target position of the moving target in the local video picture relative to the expected position is greater than a preset threshold value, a prompt control for guiding the moving target to move to the expected position is presented in the floating layer above the local video picture according to the offset of the target position relative to the expected position.

  • Publication number: 20220025282
    Abstract: Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.

  • Publication number: 20210363439
    Abstract: Method of refining whole crude oil or a wide cut crude oil, the methods comprising a combination of a hydrotreating reactor, a distillation tower, and an optional flash evaporation separator. The methods can also include light ends processing, fluid catalytic cracking, reforming, hydrocracking, and demetalization. In some methods a whole crude oil is first processed through a flash evaporation separator to create a wide cut crude oil and in other methods, the flash evaporation separator is not used as the whole crude oil is first treated in a hydrotreater.

  • Publication number: 20200095510
    Abstract: The present disclosure relates to processes for producing biofuel compositions by processing hydrocarbon co-feed and a bio-oil obtained via hydrothermal liquifaction (HTL) of a cellulosic biomass to form an HTL oil. The cellulosic mass can be processed at an operating temperature of about 425° C. or less and an operating pressure of about 200 atm or less. The HTL oil is co-processed with a hydrocarbon co-feed (e.g., petroleum fraction) in a cracking unit, such as an FCC unit, a coker unit or a visbreaking unit, in the presence of a catalyst to produce a cracked product (biofuel). The bio content of the cracked product provides RIN credits for the cracked product.

  • Patent number: 10550334
    Abstract: A process is disclosed for shifting the product of a hydrocracker in a hydrocarbon refinery back and forth from a more naphtha focused product slate to a more diesel focused product slate to take advantage of price and demand shifts between gasoline and diesel by using a naphtha selective catalyst and temporarily passivating the catalyst with a basic material such as ammonia in the hydrocracker. The ammonia passivates the acid catalyst sites on the catalyst and produces more total liquids and more diesel with attractive cold flow and pour point properties for a temporary period. When implemented in a temporary manner and the flow of ammonia is suspended the hydrocracker product slate returns to a more gasoline focused slate.

  • Publication number: 20190345430
    Abstract: The present disclosure relates to completely closed systems suitable for bio-processing of cellular samples, for example peripheral blood samples used for immunotherapy applications, and related methods of use. The systems are not open to the air, thus allowing for sterile sample processing and transfer of the sample throughout the entirety of bio-processing. Each component of the disclosed systems contains a unique identifier, allowing for traceability of the sample as it proceeds through the various steps involved in bio-processing. The identifier ultimately traces the sample back to the patient from which the sample was derived. Certain embodiments provide a unique freezing bag for long-term storage of cellular samples. The freezing bag has a unique identifier that allows for easy traceability and retrieval of a bio-archived sample and at least two ports, one for sample testing, another for sterile docking to a device that allows for delivery of its contents to a patient.
