Dual Functional Material Regeneration

Stable gas yield over cycles

Dual functional materials for sorption-enhanced hydrogen production from biomass maintain stable total gas yield over cycles using a dry reforming of methane regeneration strategy, outperforming high-temperature calcination and reverse Boudouard reaction regeneration.

Advantages

More stable cycling

The dry reforming of methane regeneration avoids sintering and carbon framework collapse, keeping total gas yield nearly stable over five cycles.

Higher yield

With DRM-based regeneration, the average total gas yield over five cycles reaches 42.6 mmol/g, outperforming the other two strategies.

Avoids sintering

High-temperature calcination causes gradual sintering of the DFMs, whereas DRM-based regeneration avoids this issue.

Applications

• Biomass-derived hydrogen：Produce hydrogen from biomass with stable cycling.
• Hydrogen production：Enhance hydrogen yield via sorption-enhanced reforming.
• Sorption-enhanced reforming：Resolve regeneration deactivation of dual-functional materials.
• Renewable fuels：Convert biomass into renewable hydrogen fuel.
