Patent number: 11591226Abstract: The present development is a process to produce commodity chemicals such as methanol and syngas using an integrated plasma catalysis technology. The method comprises providing a fixed or fluidized bed reactor having a microwave plasma flame and a catalyst bed with a catalyst, wherein the catalyst is an alloyed bimetallic nanowire. In the process, the plasma flame fluidizes the catalyst thereby producing a more effective catalyst than the non-fluidized catalyst. It is anticipated that the reactor can have a throughput capacity of up to 30 Lpm/kW and can be effective for the conversion of CO2, CH4, air, water, and combinations thereof, through reactions such as pure CO2 splitting, reverse water gas shift (RWGS) for CO production, methanol synthesis, and plasma reforming of methane, thereby making a system that would be attractive for small GTL units.Type: GrantFiled: August 24, 2021Date of Patent: February 28, 2023Assignee: Advanced Energy Materials, LLCInventors: Mahendra Sunkara, Sivakumar Vasireddy, Vivekanand Kumar, Juan He, Tu Nguyen, Veerendra Atla

Patent number: 11183682Abstract: The present development is a process for the preparation of nanowire synthesis, coatings and uses thereof. Lithium titanate (LTO) nanowires are synthesized using a continuous hydrocarbon/plasma flame process technology combined with the dry impregnation method. The resulting LTO nanowires can be used as electro active anode materials for lithium ion batteries. The coating parameters, such as thickness, porosity of the film, packing density, and viscosity are controlled using the length of the nanowires, calendaring pressure, and slurry composition.Type: GrantFiled: August 29, 2019Date of Patent: November 23, 2021Assignee: Advanced Energy Materials, LLCInventors: Mahendra Kumar Sunkara, Vivekanand Kumar, Veerendra Atla

Patent number: 11180702Abstract: The present development is a metal particle coated nanowire catalyst for use in the hydrodesulfurization of fuels and a process for the production of the catalyst. The catalyst comprises titanium(IV) oxide nanowires wherein the nanowires are produced by exposure of a TiO2—KOH paste to microwave radiation. Metal particles selected from the group consisting of molybdenum, nickel, cobalt, tungsten, or a combination thereof, are impregnated on the metal oxide nanowire surface. The metal impregnated nanowires are sulfided to produce catalytically-active metal particles on the surface of the nanowires The catalysts of the present invention are intended for use in the removal of thiophenic sulfur from liquid fuels through a hydrodesulfurization (HDS) process in a fixed bed reactor. The presence of nanowires improves the HDS activity and reduces the sintering effect, therefore, the sulfur removal efficiency increases.Type: GrantFiled: January 31, 2020Date of Patent: November 23, 2021Assignee: Advanced Energy Materials, LLCInventors: Mahendra K. Sunkara, Sivakumar Vasireddy, Juan He, Vivekanand Kumar
