Abstract
The new catalyst, Al 2O 3·Na 2O· xH 2O/NaOH/Al(OH) 3, was made by means of hydrolyzation and hydration of sodium aluminum oxide (Al 2O 3·Na 2O). Hydrogen and hydrogen-rich gas were produced through the reaction of cellulose with the catalyst and steam. In order to avoid production of tar, the gasification temperature is controlled at ≤673 K. The temperature of producing hydrogen is controlled at about 473–623 K. The conversion degree of hydrogen from cellulose at about 473–673 K could come up to 59.63%. The production of hydrogen-rich gas was set at about 673 K. The gasification residue could be used as material for combustion. Al 2O 3·Na 2O could be regenerated from the byproducts Al 2O 3 and Na 2CO 3 produced in the combustion process. The catalyst could be re-prepared from the regenerative Al 2O 3·Na 2O.
