摘要: Abstract The pyrolysis and combustion characteristics of sludge pellet (SP), camphor (CP) sludge–camphor (SCP, 50% ratio) were studied via thermogravimetric analysis. samples heated from ambient temperature to 1073 K at various heating rate (5, 10, 20, 40 K/min) in nitrogen air atmosphere. Heating had a substantial effect on mass loss both pyrolyzing oxidizing conditions. thermal behavior SCP was the integration SP CP. Onset offset temperatures lay between that CP rate. kinetic parameters process evaluated using two iso-conversional models (Flynn–Wall–Ozawa Starink). Kinetic analysis results showed activation energy highly depended conversion which indicated existence complex multi-step mechanism. Eα value for (SCP) lower than single (SP CP). Some synergistic effects happened during pyrolysis.
