Development of Bi-functional Catalyst/Sorbent Material for Ultra-Pure Hydrogen Production with In-situ CO2 Removal through Sorption Enhanced Steam Methane Reforming

This invention introduces a bifunctional Ni/CaO–mayenite catalyst for sorption-enhanced steam methane reforming (SE-SMR), enabling cost-effective blue hydrogen production with in-situ CO₂ removal. The process integrates catalytic reforming and carbon capture in a single step, achieving high hydrogen yield, reduced carbon footprint, lower costs, and scalability for sustainable clean energy.
