Patent number: 11732203Abstract: An ebullated bed hydroprocessing system is upgraded and operated at modified conditions using a dual catalyst system to produce less fouling sediment. The less fouling sediment produced by the upgraded ebullated bed reactor reduces the rate of equipment fouling at any given sediment production rate and/or concentration compared to the sediment produced by the ebullated bed reactor prior to upgrading. In some cases, sediment production rate and/or concentration are maintained or increased, after upgrading the ebullated bed reactor, while equipment fouling is reduced. In other cases, sediment production rate and/or concentration are increased, after upgrading the ebullated bed reactor, without increasing equipment fouling. In some cases, sediment production rate and/or concentration are decreased by a given percentage, after upgrading the ebullated bed reactor, and the rate of equipment fouling is decreased by a substantially greater percentage.Type: GrantFiled: August 16, 2021Date of Patent: August 22, 2023Assignee: HYDROCARBON TECHNOLOGY & INNOVATION, LLCInventors: David M. Mountainland, Brett M. Silverman, Michael A. Rueter, Lee Smith

Patent number: 11421164Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to improve the quality of vacuum residue. The improved quality of vacuum residue can be provided by one or more of reduced viscosity, reduced density (increased API gravity), reduced asphaltene content, reduced carbon residue content, reduced sulfur content, and reduced sediment. Vacuum residue of improved quality can be produced while operating the upgraded ebullated bed reactor at the same or higher severity, temperature, throughput and/or conversion. Similarly, vacuum residue of same or higher quality can be produced while operating the upgraded ebullated bed reactor at higher severity, temperature, throughput and/or conversion.Type: GrantFiled: June 6, 2017Date of Patent: August 23, 2022Assignee: Hydrocarbon Technology & Innovation, LLCInventors: David Mountainland, Brett M.

Patent number: 11414607Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to increase rate of production of converted products. The rate of production is achieved by increasing reactor severity, including increasing the operating temperature and at least one of throughput or conversion. The dual catalyst system permits increased reactor severity and provides increased production of converted products without a significant increase in equipment fouling and/or sediment production. In some cases, the rate of production of conversion products can be achieved while decreasing equipment fouling and/or sediment production.Type: GrantFiled: September 7, 2016Date of Patent: August 16, 2022Assignee: Hydrocarbon Technology & Innovation, LLCInventors: David M.

Patent number: 11414608Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to hydroprocess opportunity feedstocks (i.e., lower quality heavy oils or lower quality feedstock blends) while maintaining or increasing the rate of production of converted products. The dual catalyst system improves the ability of the upgraded ebullated bed hydroprocessing system to accommodate and withstand negative effects of periodic use of opportunity feedstocks (e.g., without significantly increasing equipment fouling and/or sediment production). In some cases, an upgraded ebullated bed reactor using the dual catalyst system can hydroprocess opportunity feedstocks while decreasing equipment fouling and/or sediment production.Type: GrantFiled: September 7, 2016Date of Patent: August 16, 2022Assignee: Hydrocarbon Technology & Innovation, LLCInventors: David M.

Patent number: 11118119Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to produce less fouling sediment. The dual catalyst system more effectively converts sediment-forming precursors to produce sediment that is less fouling than sediment produced using only the heterogeneous catalyst and not the dispersed metal sulfide particles. The dual catalyst system provides for a lower rate of equipment fouling for a given sediment production rate and/or concentration. In some cases, sediment production rate and/or concentration can be maintained or increased while equipment fouling is reduced. In some cases, sediment production rate and/or concentration can be increased without increasing equipment fouling.Type: GrantFiled: February 28, 2018Date of Patent: September 14, 2021Assignee: HYDROCARBON TECHNOLOGY & INNOVATION, LLCInventors: David M.

Patent number: 11091707Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles, which permits recycling of vacuum bottoms without recycle buildup of asphaltenes. The dual catalyst system more effectively converts asphaltenes in the ebullated bed reactor and increases asphaltene conversion by an amount that at least offsets higher asphaltene concentration resulting from recycling of vacuum bottoms. In this way, there is no recycle buildup of asphaltenes in upgraded ebullated bed reactor notwithstanding recycling of vacuum bottoms. In addition, residual dispersed metal sulfide catalyst particles in the vacuum bottoms can maintain or increase the concentration of the dispersed metal sulfide catalyst in the ebullated bed reactor.Type: GrantFiled: October 7, 2019Date of Patent: August 17, 2021Assignee: HYDROCARBON TECHNOLOGY & INNOVATION, LLCInventors: Michael A.

Patent number: 7709411Abstract: Multicomponent nanoparticles include two or more dissimilar components selected from different members of the group of noble metals, base transition metals, alkali earth metals, and rare earth metals and/or different groups of the periodic table of elements. The two or more dissimilar components are dispersed using a polyfunctional dispersing agent such that the multicomponent nanoparticles have a substantially uniform distribution of the two or more dissimilar components. The polyfunctional dispersing agent may include organic molecules, polymers, oligomers, or salts of these. The molecules of the dispersing agent bind to the dissimilar components to overcome same-component attraction, thereby allowing the dissimilar components to form multicomponent nanoparticles. Dissimilar components such as iron and platinum can be alloyed together using the dispersing agent to form substantially uniform multicomponent nanoparticles, which can be used alone or with a support.Type: GrantFiled: April 9, 2009Date of Patent: May 4, 2010Assignee: Headwaters Technology Innovation, LLCInventors: Bing Zhou, Sukesh Parasher, Michael Rueter

Patent number: 7632774Abstract: Supported catalysts include an inorganic solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. The functionalization of the support material is optimized by (i) limiting the amount of water present during the functionalization reaction, (ii) using a concentrated mineral acid or derivative thereof, and/or (iii) increasing the reaction temperature and/or reaction pressure. The acid-functionalized support material serves as a support for a metal nanoparticle catalyst. The nanocatalyst particles are preferably bonded to the support material through an organic molecule, oligomer, or polymer having functional groups that can bind to both the nanocatalyst particles and to the support material. The supported catalysts can advantageously be used for the direct synthesis of hydrogen peroxide from hydrogen and oxygen feed streams.Type: GrantFiled: March 30, 2006Date of Patent: December 15, 2009Assignee: Headwaters Technology Innovation, LLCInventors: Michael A.
