Patent number: 11668014Abstract: The disclosure relates to an electrolyzer reactor suitable for the reduction of organic compounds. The reactor includes a membrane electrode assembly with freestanding metallic meshes which serve both as metallic electrode structures for electron transport as well as catalytic surfaces for electron generation and organic compound reduction. Suitable organic compounds for reduction include oxygenated and/or unsaturated hydrocarbon compounds, in particular those characteristic of bio-oil (e.g., alone or a multicomponent mixtures). The reactor and related methods provide a resource- and energy-efficient approach to organic compound reduction, in particular for bio-oil mixtures which can be conveniently upgraded at or near their point of production with minimal or no transportation.Type: GrantFiled: April 10, 2020Date of Patent: June 6, 2023Assignee: BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITYInventors: James E. Jackson, Chun Ho Lam, Christopher M. Saffron, Dennis J. Miller

Patent number: 9951431Abstract: A process and related electrode composition are disclosed for the electrocatalytic hydrogenation and/or hydrodeoxygenation of organic substrates such as biomass-derived bio-oil components by the production of hydrogen atoms on a catalyst surface followed by the reaction of the hydrogen atoms with the organic reactants. Biomass fast pyrolysis-derived bio-oil is a liquid mixture containing hundreds of organic compounds with chemical functionalities that are corrosive to container materials and are prone to polymerization. A high surface area skeletal metal catalyst material such as Raney Nickel can be used as the cathode. Electrocatalytic hydrogenation and/or hydrodeoxygenation convert the organic substrates under mild conditions to reduce coke formation and catalyst deactivation. The process converts oxygen-containing functionalities and unsaturated bonds into chemically reduced forms with an increased hydrogen content.Type: GrantFiled: October 23, 2013Date of Patent: April 24, 2018Assignee: BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITYInventors: James E.

Patent number: 7477529Abstract: A high-voltage power supply (10) includes: a power scaling section (130) that receives an input voltage signal and converts the input voltage signal to a controllable DC voltage; a push-pull converter (140) for converting the controllable DC voltage to a high-frequency wave; and a voltage multiplier (200) receiving the high-frequency wave generated by the push-pull converter (140) and performing successive voltage doubling operations to generate a high-voltage DC output. In one implementation, the voltage multiplier (200) receives a square wave having a frequency of approximately 100 kHz and outputs an adjustable DC voltage of approximately 0-to-30 kV. In one implementation, the high-voltage power supply (10) includes an insulation system (250) for the voltage multiplier module (200), such an insulation system being formed of n insulating layers and m conducting strips positioned between successive insulating layers.Type: GrantFiled: July 31, 2003Date of Patent: January 13, 2009Assignee: Honeywell International inc.Inventors: Magdy Salama, Mehrdad Kazerani, Chun Ho Lam

Patent number: 6782701Abstract: A system and method for an engine bleed flow-sharing control system is disclosed. For a multi-engine bleed system, one (10) of the engines is selected as the master channel (15) such that the bleed air supply pressure of the control system receiving the bleed air is controlled (11, 12, 13) to achieve a desirable supply pressure range. To slave the other engine airflow control channels (25, 35, 45), the airflow rate (14) is also measured in the master channel (15) and the measured airflow rate is used as the airflow setpoint for other channels (25, 35, 45). The difference between the airflow setpoint and the airflow rate in the other channel is applied to control (21, 31, 41) the pressure or the valve/actuator opening area at the inlet of that channel (25, 35, 45).Type: GrantFiled: January 22, 2003Date of Patent: August 31, 2004Assignee: Honeywell International Inc.Inventors: Guang Jun Liu, Chun Ho Lam
