A heat exchanger 124 transfers thermal energy generated by a carbon-neutral thermal energy source 130 to cooled compressed air conveyed from reservoir 120 to generate a heated compressed air. An expander 140 is solely responsive to the heated compressed air by heat exchanger 124 to produce power and generate an expanded air. Expander 140 is effective to reduce a temperature of the expanded air by expander 140, and thus a transfer of thermal energy from an expanded exhaust gas received by a recuperator 146 (used to heat the expanded air by the first expander) is effective for reducing waste of thermal energy in exhaust gas cooled by recuperator 146.Type: GrantFiled: April 23, 2020Date of Patent: February 22, 2022Assignee: DRESSER-RAND COMPANYInventor: Joseph T.

Patent number: 11236273Abstract: The invention relates to a process for producing energy products, notably fuel, by catalytic cracking of a hydrocarbon-based solid material without coke formation, in which a cracking dispersion (40) is heated, said dispersion comprising: a solid material (1) in divided form containing at least one hydrocarbon-based compound; a liquid (30) which is inert with respect to catalytic cracking; so that the cracking dispersion (40) reaches a temperature suitable for allowing catalytic cracking of at least one hydrocarbon-based compound; characterized in that the cracking temperature is reached by mixing an amount of cracking dispersion (40) and an amount of inert liquid (30) brought to a temperature above the cracking temperature, such that the mixture formed reaches a temperature above the cracking temperature and below the temperature for formation of coke, dioxin and furan. The invention also relates to a device for performing such a process.Type: GrantFiled: December 22, 2017Date of Patent: February 1, 2022Inventor: Pierre Dumons

Circular rotor blade plates have scalene triangularly shaped cavities with long leading edge sides receiving compressed air flow, short trailing edge sides and an open peripheral air portal. Adjacently mounted blades are offset such that one air portal then another air portal is presented to compressed air flow from nozzles during rotation. Each turbine shroud has a manifold feeding compressed air to the nozzle, as a venturi, due alternating presented air portals. Each rotor carries permanent magnets on its radially outboard segments. Bilateral stationary stators are transversely fixedly mounted outboard of the rotating rotor subassemblies. Electrical outputs carry power from the stators when the rotor subassemblies rotate.Type: GrantFiled: December 17, 2020Date of Patent: December 7, 2021Assignee: Bizhub Group LLCInventor: Peter Mark Evans
