  • Patent number: 10717061
    Abstract: A fluidized gas reactor includes a system for preventing a fluidizing gas comprising a reactant from premature reaction. The fluidized gas reactor includes a reaction chamber including a particle bed; a gas distribution plate having a plurality of openings therethrough, wherein each opening opens into the reaction chamber; and a plurality of vertical fluidizing gas inlet tubes, each of the fluidizing gas inlet tubes being in fluid communication with one of the openings in the gas distribution plate. Each fluidizing gas inlet tube is configured to receive a fluidizing gas and transport the fluidizing gas to the reaction chamber.

  • Patent number: 10682620
    Abstract: Entrained particles from an exhaust gas stream may be removed from the gas stream with a device including a housing having a top, an inner surface, and a bottom with a hole passing therethrough, where the housing further includes an impact surface. An entrance pipe guides the exhaust gas stream into the housing toward the impact surface, and is arranged so that the entrance pipe has an inner diameter x; and the impact surface is separated from the opening of the entrance pipe by a distance y, wherein y is between 3x and ?x. An exit pipe guide the exhaust gas stream out of the housing. A receptacle is removably connected to the hole in the bottom of the housing. The impact surface diverts the exhaust gas stream from a first flow direction to a second flow direction, causing the entrained particles to fall from the exhaust gas stream into the receptacle before entering the exit pipe.

  • Patent number: 10660341
    Abstract: A counter-rotating dough making mechanism, including a drive shaft (9) that is provided with an upper dough hook assembly (1) and a lower dough hook assembly (2) is disclosed. The lower dough hook assembly (2) is preferably provided with a stir plate (3) which enhances the thorough mixing of flour during dough kneading. The upper dough hook assembly (1) and the lower dough hook assembly (2) are connected by gears (42a, 42b, 42c) so that they rotate synchronously but in the opposite direction. By the counter-rotating action of the upper dough hook assembly (1) and the lower dough hook assembly (2), the dough making process is more effective as compared to the usual single piece dough hook as used in many stand mixers. The design and construction of the disclosed counter-rotating dough making mechanism is simple, robust, and reliable, and can deliver superior performance in dough making.

  • Patent number: 10639586
    Abstract: A method and an integrated system for reducing CO2 emissions in industrial processes. The method and integrated system (100) capture carbon dioxide (CO2) gas from a first gas stream (104) with a chemical absorbent to produce a second gas stream (106) having a higher concentration of carbon monoxide (CO) gas and a lower concentration of CO2 gas as compared to first gas stream. The CO gas in the second gas stream is used to produce C5 to C20 hydrocarbons in an exothermic reaction (108) with hydrogen (H2) gas (138). At least a portion of the heat generated in the exothermic reaction is used to regenerate the chemical absorbent with the liberation of the CO2 gas (128) captured from the first gas stream. Heat captured during the exothermic reaction can, optionally, first be used to generate electricity, wherein the heat remaining after generating electricity is used to thermally regenerate the chemical absorbent.
