Investigation of the Thermal Decomposition Kinetics of Modified Carboxyl Hydroxypropyl Sesbania Gum
Abstract:
The viscosities of hydroxypropyl Sesbania Gum, carboxyl hydroxypropyl Sesbania Gum and modified carboxyl hydroxypropyl Sesbania Gum at different temperatures and their pyrolysis kinetics have been studied. The kinetic parameters under air and N2 were calculated. The heat-stability of the modified carboxyl hydroxypropyl Sesbania Gum was carefully studied. The results indicate that the viscosity heat-stability and heatstability for pyrolysis of modified carboxyl hydroxypopyl Sesbania Gum surpassed those of hydroxypropyl and carboxylhydroxypropyl Sesbania Gum. The results also indicate that the mechanism of thermal decomposition can be described by the model of random initation.
