Combined capture and reduction of CO₂ to methanol using a dual-bed packed reactor

Recently, carbon capture and reduction (CCR) technology has gained interest to directly convert CO₂ to value-added products without requiring purification of CO₂ and its subsequent transportation. CCR to methanol in one dual function material (DFM) poses mechanistic and kinetic challenges. To counteract this, a process...

Direct and continuous conversion of flue gas CO₂ into green fuels using dual function materials in a circulating fluidized bed system

Carbon capture and utilization (CCU) technologies, such as CO₂ methanation, generally require energy-intensive CO₂ capture and separation processes prior to catalytic CO₂ conversion. In contrast, integrated CO₂ capture and reduction (CCR) technologies that use dual function materials (DFM) can...

PBI mixed matrix hollow fiber membrane: Influence of ZIF-8 filler over H₂/CO₂ separation performance at high temperature and pressure

High performance and commercially attractive mixed-matrix membranes were developed for H₂/CO₂ separation via a scalable hollow fiber spinning process. Thin (~300 nm) and defect-free selective layers were successfully created with a uniform distribution of the nanosized (~60 nm) zeolitic-imidazole framework (ZIF-8) filler...
