    Abstract: A hydrocarbon is reacted with water in the presence of a catalyst to form hydrogen, carbon monoxide, and carbon dioxide. Hydrogen is selectively allowed to pass through a hydrogen separation membrane to a permeate side of a reactor, while water and carbon-containing compounds remain in a retentate side of the reactor. An outlet stream is flowed from the retentate side to a heat exchanger. The outlet stream is cooled to form a cooled stream. The cooled stream is separated into a liquid phase and a vapor phase. The liquid phase is flowed to the heat exchanger and heated to form steam. The vapor phase is cooled to form condensed water and a first offgas stream. The first offgas stream is cooled to form condensed carbon dioxide and a second offgas stream. The steam and the second offgas stream are recycled to the reactor.

  • Patent number: 11939247
    Abstract: A method by which an environmental energy (e.g., wave energy) is harvested, converted into electrical power, and thereafter used to electrolyze seawater into hydrogen and chlorine gases. Those gases are recombined into hydrogen chloride from which is formed hydrochloric acid solution which is diluted and deposited at a depth sufficient to ensure its neutralization and sequestration for a significant period of time (e.g., for over a millennium). By removing chloride ions from a portion of the sea adjacent to its upper surface and depositing them into a portion of the sea more adjacent to its bottom, acidity is shifted from the surface to base of the sea, and the surface ocean is given a greater ability to absorb and buffer atmospheric carbon dioxide without a corresponding increase in acidity.

  • Patent number: 11577252
    Abstract: An example system includes an array of retaining features in a microfluidic cavity, an array of thermally controlled releasing features, and a controller coupled to each releasing feature in the array of releasing feature. Each retaining feature in the array of retaining features is to position capsules at a predetermined location, the capsules having a thermally degradable shell enclosing a biological reagent therein. Each releasing feature in the array of releasing features corresponds to a retaining feature and is to selectively cause degradation of the shell of a capsule. Each releasing feature is to generate thermal energy to facilitate degradation of the shell. The controller is to selectively activate at least one releasing feature in the array of thermally controlled releasing features to release the biological reagent in the capsules positioned at the retaining feature corresponding to the activated releasing feature.
