Abstract: The catalytic thermal decomposition of rubber was studied with TG-DTG. The thermal kinetic data were analyzed according to the single and multiple scan methods. The decomposition process of rubber was a 3/2 order reaction, whose kinetic equation was as follows： , and whose activation energy and pre-exponential factor were 148—162 kJ/mol and 28—32 respectively.
