Mechanism of synergistic effects and kinetics analysis in catalytic co-pyrolysis of water hyacinth and HDPE

Co-pyrolysis of water hyacinth (Eichhornia crassipes) and HDPE is a commercially effective method to mitigate the pressure environmental pollution problem invasive alien species. In this paper, thermal behavior kinetic evaluation two raw materials with or without catalysts have been investigated. The mechanism catalytic pyrolysis was also investigated by analyzing free radicals generated during pyrolysis. results showed that heating rates had negligible effect on process. addition could reduce formation char be conducive complete reaction higher value comprehensive index (CPI). sample containing 75% exhibited strongest synergistic in co-pyrolysis, lowest difference between experimental theoretical weight loss (ΔW) activation energy among co-pyrolysis samples. However, 25% an inhibiting due positive ΔW main decomposition temperature. Whereas HZSM-5 compared blends indicating presence co-pyrolysis. promotion then demonstrated abundance This paper aims provide some suggestions solution for alleviation crisis.
