CO2 activation of olive bagasse for hydrogen storage

摘要: Hydrogen is considered as the most promising future fuel, its combustion generates only water vapor besides energy. However, finding efficient, safe and low-cost storage methods basic impediment for adoption of hydrogen fuel. For this purpose, an ultramicroporous activated carbon was successfully synthesized from biomass residues; olive bagasse. The material prepared throw physical activation, using dioxide activating agent, under controlled thermal conditions. Then, it tested at cryogenic room temperature textural characterizations showed a highly tailored porous texture adequate gas adsorption. totality created microporosity narrow range (d < 0.7 nm). Interestingly, measured median pore width about 0.65 nm, likely optimum size This feature accorded AC with exceptional H2 capacity, achieving 3.34 wt % liquid nitrogen temperature. It has outperformed Zeolites MOFs. © 2016 American Institute Chemical Engineers Environ Prog, 36: 315–324, 2017
