摘要:
Embodiments of the invention are directed to methods, processes, and systems for safely and reliably purifying hydrogen from a gas mixture containing hydrogen and oxygen. A process comprises injecting a flammability suppressor into a photocatalytic water-splitting reactor to form a suppressed feed source gas, introducing the suppressed feed source gas to a first membrane separation unit, and collecting a hydrogen product gas stream.
摘要:
A process involving membrane-based gas separation and power generation, specifically for controlling carbon dioxide emissions from gas-fired power plants. The process includes a compression step, a combustion step, and an expansion/electricity generation step, as in traditional power plants. The process also includes a sweep-driven membrane separation step and a carbon dioxide removal or capture step. The carbon dioxide removal step is carried out on a portion of gas from the compression step.
