| Abstract: | In this paper, the delignification kinetics of silvergrass in auto-catalyzed ethanol-water pulping was studied. It was showed that the delignification of silvergrass occurred in two phases: principal delignification and residual lignin removal, and the delignification reaction followed a first order reaction. The calculated Arrhenius activation energy Ep (principal phase) and Er (residual phase) were 77.13kJ/mol and 156.7 kJ/mol respectively. |
