Abstract

Cellulose [C₆(H₂O)₅] was co-ground with calcium (Ca(OH)₂) and nickel (Ni(OH)₂) hydroxides, followed by heating the ground samples up to 1000 °C for determination of temperature range at which hydrogen (H₂) gas can be generated. The results showed that the main gaseous products were; H₂, CH₄, H₂O, CO, and CO₂with H₂as the dominant gas generated between 350 and 550 °C. Analyses of the gaseous products by TG-MS and gas-chromatography, and solid products by TG-DTA and XRD showed that CO₂gas was fixed as CaCO₃at temperatures between 350 to 600 °C allowing generation of H₂gas with concentrations ranging from 90 to 99% with carbon oxide (CO, CO2) concentrations less than 1%. A plausible reaction mechanism is attributed to the interaction between cellulose and Ca(OH)₂to transform the carbon in cellulose into CaCO₃, to which nickel works as catalyst. Accompanying the carbonate formation reaction, H₂emission occurs correspondingly. This process offers a new approach to produce H₂gas from the renewable biomass sources.
