Zusammenfassung:Hydrogen adsorption characteristics of woodceramics, made from radiata pine wood fiber boards carbonized at 1 473 K after impregnation with phenolic resin, with and without chemical treatment in an alkaline (KOH) or an acid (H2SO4) solution were investigated The hydrogen adsorption capacity is improved by chem- ical treatment. The chemical treatment by KOH improves the adsorption capacity more than by H2SO4. The improvement of the capacity level, in any solution, is dependent on the type of chemical in the solution and its concentration. The maximum hydrogen capacity measured at 93K is mass fraction about w(H) = 2% for the woodceramics after chemical treatment in a volume fraction ~ = 50% KOH solution, although that is about w(H) = 0.7% for one without chemical treatment. The microscopic condition of pores in the woodceramics is thought to vary after chemical treatment.
