Abstract: A system for generating a gas may include a pyrolysis reactor configured to pyrolyze a hydrocarbon to generate hydrogen and carbon. The pyrolysis reactor is further configured to contact the carbon with an agitated bed comprising metal oxide substrate particles to generate carbon-coated metal oxide particles. A technique for generating a gas may include agitating metal oxide substrate particles to form an agitated bed in a pyrolysis reactor. The technique may further include pyrolyzing, in the pyrolysis reactor, a hydrocarbon to generate hydrogen and carbon. The technique may further include contacting, in the pyrolysis reactor, the carbon with the agitated bed to generate carbon-coated metal oxide particles.

Abstract: The disclosure describes a system for generating hydrogen gas from a hydrocarbon through pyrolysis with reduced soot formation and increased carbon loading. The system includes one or more pyrolysis reactors configured to generate the hydrogen gas from the hydrocarbon through pyrolysis. Each pyrolysis reactor of the one or more pyrolysis reactors includes one or more fibrous substrates and a concentration sensor downstream of at least one fibrous substrate of the one or more fibrous substrates. Each fibrous substrate of the one or more fibrous substrates defines a deposition surface for carbon generated from the pyrolysis of the hydrocarbon and includes a plurality of fibers configured to maintain chemical and structural stability between 850° C. and 1300° C. The concentration sensor is configured to measure a concentration of at least one of a hydrocarbon byproduct or a hydrocarbon soot precursor, such as acetylene.

Abstract: The disclosure describes a method for disinfecting an aircraft cabin that includes injecting a non-peroxide disinfectant into an environmental control system of an aircraft and discharging cabin supply air through the environmental control system to discharge the non-peroxide disinfectant into the aircraft cabin. In some instances, the method includes aerosolizing the disinfectant into a plurality of liquid droplets while injecting the disinfectant into the environmental control system. In some instances, the injected disinfectant includes a non-corrosive, non-toxic disinfectant, such that the disinfectant may be discharged into the aircraft cabin in the presence of personnel in the aircraft cabin.
