摘要： A process and system for generating hydrogen gas are described, in which water is electrolyzed to generate hydrogen and oxygen, and a feedstock including oxygenate(s) and/or hydrocarbon(s), is non-autothermally catalytically oxidatively reformed with oxygen to generate hydrogen. The hydrogen generation system in a specific implementation includes an electrolyzer arranged to receive water and to generate hydrogen and oxygen therefrom, and a non-autothermal segmented adiabatic reactor containing non-autothermal oxidative reforming catalyst, arranged to receive the feedstock, water, and electrolyzer-generated oxygen, for non-autothermal catalytic oxidative reforming reaction to produce hydrogen. The hydrogen generation process and system are particularly advantageous for using bioethanol to produce green hydrogen.

摘要： The present invention provides a process for recovering hydrogen and carbon dioxide from a process stream utilizing a carbon dioxide separation unit and two membrane separation units. The present invention further provides a process within a hydrogen generation plant to increase recovery of hydrogen and capture equal to or greater than 80% of the carbon dioxide in the syngas stream. By using the process of the present invention, especially in terms of a hydrogen generation plant, it is possible to increase recovery of hydrogen and capture of the carbon dioxide in the syngas stream by balancing the recycle of the hydrogen rich permeate from the hydrogen membrane separation unit to the process unit and/or the water gas shift as capacity allows when a carbon dioxide separation unit, a carbon dioxide membrane separation unit and a hydrogen membrane separation unit are utilized.
