Modulating the porosity of activated carbons via pre-mixed precursors for simultaneously enhanced gravimetric and volumetric methane uptake

Autor: Altwala, Afnan, Mokaya, Robert

Pre-mixed precursors containing biomass-derived carbonaceous matter of varying O/C ratio and polypyrrole have been used as starting materials to modulate the porosity of activated carbons. The use of pre-mixtures of polypyrrole and CNL carbon (from a

Direct and mild non-hydroxide activation of biomass to carbons with enhanced CO2 storage capacity

Autor: Altwala, Afnan, Mokaya, Robert

Potassium oxalate (PO) was trialled as a non-corrosive and less toxic activating agent for the direct activation of biomass (sawdust, SD). The PO + SD mixtures were activated either in powder form or after compaction into pellets. The resulting activ
