Abstract
In the exploration of the mechanism of corn stovers pyrolysis and gasification, the kinetic parameters is of great significance for regulating the production of target products. Although the kinetic calculations of corn stovers pyrolysis gasification have been reported, the study of kinetics under high pressure and supercritical conditions is still very limited. Therefore, the effect of pressure on the kinetics of corn stovers pyrolysis and gasification reaction was investigated through experiments of atmospheric pressure, high pressure thermogravimetry and supercritical water gasification (SCWG). Different kinetic calculation models were used. It was found that an increase in pressure would increase the activation energy value and inhibit the generation of gas products, but at the same time it would also promote the interaction between gas components and samples. Through this research, this work can provide scientific and technological references for the mechanism of pyrolysis gasification under pressure and the regulation of target products.
