Biomass gasification is a viable solution for generating H 2 ; however, the syngas produced must be upgraded to make H 2 -containing streams suitable for other applications, such as renewable methanol production, by adjusting the H 2 /CO ratio. In this study, for the first time in the literature, the separation properties of carbon hollow fiber membranes in binary and quaternary H 2 -containing mixtures with varying compositions were systematically explored. It was found that the developed carbon membranes exhibit relatively good selectivity for (H 2 +CO 2 ) in mixtures with other gases such as N 2 and CO, which are commonly present in syngas. A CO permeance of 0.8−1 GPU and a H 2 /CO selectivity of 30 were achieved for the first time through both single gas and mixed gas permeation testing. Furthermore, in the context of using these membranes for syngas upgrading, such as in an integrated biomass-to-biofuel (methanol) process for hydrogen enrichment or carbon capture and conversion, a technical feasibility analysis based on the separation performance of the carbon membrane system for syngas ratio adjustment and N 2 removal was carried out. The results indicate that the prepared carbon membranes have the potential to adjust the H 2 /CO ratio to 1−3 if a N 2 removal ranging from 80 to 90% is acceptable.

Biomass photoreforming is a promising way of producing sustainable hydrogen thanks to the abundant sources of biomass feedstocks. Solar energy provides the heat and driven force to initial biomass oxidation coupled with H2 evolution. Currently, biomass photoreforming is still far from plant‐scale applications due to the lower solar energy utilization efficiencies, the low H2 yield, and the lack of appropriate photoreactors. The production of H2 from photoreforming of native biomass and platform molecules was summarized and discussed with special attention to the prospects of scaling up the catalysis technology for mass production of hydrogen. The types of photoreforming including photocatalysis and photothermal catalysis were discussed consequently considering the different requirements for photoreactors. We also reviewed the photoreactors that support biomass photoreforming. Numerical simulation methods were implemented for the solid‐liquid two‐phase flow and inter‐particle radiative transfer involved in the reaction process. Developing concentrated photothermal catalytic flowed reactors is beneficial to scale‐up catalytic hydrogen production from biomass.
