Abstract

A novel thermobalance apparatus is described which alleviates some problems traditionally associated with thermogravimetric reaction studies. The new design provides direct measurement of sample temperature, elimination of external mass-transfer resistances via gas flow directly through the sample bed, and added safety using a cold-wall vessel design. The sensitivity of the balance is approximately plus or minus 10 mg for a 2-g carbon sample. The apparatus consists of a pressure vessel, a counterweighted balance arm, and a top-loading electronic balance. Results from gasification with CO//2 and O//2 show that the balance adequately measures sample weight during reaction.
