  • Patent number: 10774267
    Abstract: A method and device for converting municipal waste into energy. This method involves heating the waste in multiple sections of a chamber to produce syngas and biochar. The syngas is removed with a vacuum pump and the biochar advances to the next section and is heated to a higher temperature to release more syngas. All of the collected syngas is then transferred to a bio-reactor that removes dangerous carbon monoxide from the syngas mixture by combining the syngas with hydrogen, causing the carbon monoxide to react with the hydrogen and produce methane and water. The resulting syngas can then be used for electricity production or stored as dimethyl ether.

  • Patent number: 10633317
    Abstract: Utilizing the common knowledge formula for creation of methanol CO2+3H2?CH3OH+H2O; for each mole of carbon dioxide, three moles of hydrogen are needed to produce one equivalent unit of methanol. Mixing two gases and producing methanol can be accomplished per the one-line diagram concept, FIG. 1, and gas mixing apparatus, FIG. 2; under high pressure (from 3250 to 5000 psi) and high temperature (750 to 800° F.) without the presence of a catalyst. The hypothesis in this case is that the closer the mixing temperature is to the auto-ignition of hydrogen, the higher is the quality of the mixing environment. The mixing temperature in my invention is guided by the auto-ignition of hydrogen in this case (auto-ignition for hydrogen is 932° F. (or 500° C.) and the auto-ignition temperature for methanol is 867° F. (or 464° C.). After mixing the two gases, the result is methanol and water. The first step in this stage is to cool the substance by way of cooling tower, followed by a pressure lowering tank.

  • Patent number: 10597294
    Abstract: Among other things, the present invention encompasses the applicant's recognition that epoxide carbonylation can be performed industrially utilizing syngas streams containing hydrogen, carbon monoxide and varying amounts carbon dioxide. Contrary to expectation, the epoxide carbonylation reaction proceeds selectively in the presence of these mixed gas streams and incorporates excess CO in the syngas stream into valuable chemical precursors, resulting in hydrogen streams substantially free of CO. This is economically and environmentally preferable to performing WSGR which releases the excess carbon as CO2. The integrated processes herein therefore provide improved carbon efficiency for processes based on coal or biomass gasification or steam methane reforming.

  • Patent number: 10450195
    Abstract: Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“PDX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted (26) with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit (30) such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.

  • Patent number: 10443005
    Abstract: A carbonaceous fuel gasification system for all-steam gasification with carbon capture includes a micronized char preparation system comprising a devolatilizer that receives solid carbonaceous fuel, hydrogen, oxygen, and fluidizing steam and produces micronized char, steam, volatiles, hydrogen, and volatiles at outlets. An indirect gasifier includes a vessel comprising a gasification chamber that receives the micronized char, a conveying fluid, and steam. The gasification chamber produces syngas, ash, and steam at one or more outlets. A combustion chamber receives a mixture of hydrogen and oxidant and burns the mixture of hydrogen and oxidant to provide heat for gasification and for heating incoming flows, thereby generating steam and nitrogen. The heat for gasification is transferred from the combustion chamber to the gasification chamber by circulating refractory sand.
