  • Patent number: 11597882
    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: 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: 20180214196
    Abstract: An ablating element for use with an ablating system employable within a hollow anatomical region. The ablating element includes an elongated support body having a central axis; and, at least one thermocouple wrapped around the central body. The thermocouple provides a dual function of heating the anatomical region and measuring the temperature of the anatomical region. In a preferred embodiment a number of thermocouples are wrapped around the central body. The thermocouples are serially positioned along the central axis, thus defining segmented portions.

  • Patent number: 9903584
    Abstract: A system for converting fuel may include a first moving bed reactor, a second reactor, and a non-mechanical valve. The first moving bed reactor may include at least one tapered section and multiple injection gas ports. The multiple injection gas ports may be configured to deliver a fuel to the first moving bed reactor. The first moving bed reactor may be configured to reduce an oxygen carrying material with a fuel by defining a countercurrent flowpath for the fuel relative to the oxygen carrying material. The second reactor may communicate with the first moving bed reactor and may be operable to receive an oxygen source. The second reactor may be configured to regenerate the reduced oxygen carrying material by oxidation.

  • Publication number: 20170056090
    Abstract: The apparatus and method includes a proximal balloon subsystem including a proximal balloon positionable to a selected first location within a blood vessel to be ablated. A distal balloon subsystem including a distal balloon is positionable to a selected second location within the blood vessel to be ablated. An ablating subsystem including an ablating element is configured to be positioned between the proximal balloon and the distal balloon within the blood vessel to be ablated. An evacuation port is configured to evacuate fluid between the proximal balloon and the distal balloon.
