Abstract

In order to develop the effective utilization of biomass, the gasification behavior (changes in gasification rates against conversion) of various chars prepared from biomass at 1,000°C was studied. The gasification rate of char with CO2 measured at 900°C by a thermogravimetric balance was affected by the content of indigenous mineral matter such as calcium and potassium. The gasification behavior of chars were classified into following three groups: (1) the gasification rate reached a maximum in the higher conversion region, (2) the gasification rate profile showed two peaks around char conversion of 0.2 and 0.6 or higher, (3) the gasification rate profile fitted the random pore model. An increase in the gasification rate in a higher char conversion region was attributed to the promotion effect of the potassium catalyst. The number of active centers in the char was obtained by the O2 uptake at 200°C using pulse technique. The number of active sites was increased by potassium and calcium in biomass and the amount of O2 uptake well correlated the char gasification rate.

Pulsed reaction is one of unsteady-state operation of reactions. In a fixed bed reactor, a certain amount of reactant (char this case) was charged, and under a steady flow of an inert carrier gas (He, Ar), a small amount of reactant was injected as a pulse (width about 1 s). The effluent was analyzed with a quadrupole mass spectrometer within time resolution less than 1 s. From the response of the unreacted reactant and products, we can evaluate rapid dynamic behavior of adsorption and reaction. Especially important information is obtained using isotope labeled samples. Here we can differentiate CO from char natural 12C and 13CO from reactant 13CO2.
