چکیده
In this study, thermogravimetric measurements of nylon-6/polyethylene double-layer pouch wastes were conducted in N2 under a constant heating-rate mode, and the multiple results analyzed terms degradation features specific temperatures. Experimental show that waste pyrolysis involves one reaction stage, all parameters appear to increase with heating rate. Kinetic analysis non-isothermal data was thoroughly performed using various isoconversional model-free methods for calculations activation energy, resulting 143~215 kJ/mol over whole process. By means model-fitting method, mechanism model g(α) pre-exponential factor lnk0 are concurrently determined aid linear compensation effect. With such methodology proposed, Avrami–Erofeev kinetic A3/2 = [−ln(1 − α)]2/3 is found be most appropriate function describing along 23.14 34.26 min−1. Arrhenius thus obtained, predictions made very satisfactorily correlate experimental results. Additionally, service life thermodynamic entire process also estimated.

Pyrolysis Characteristics and Kinetics of Food Wastes
Pyrolysis is an environmental friendly alternative method compared with incineration, and the least time-consuming and smallest infrastructure footprint method compared with bio-chemical and thermo-chemical conversion. Baseline data for the pyrolysis of food waste was obtained in a kinetic study of the thermal decompositions by thermogravimetric analysis. To simulate the difference in the types...

متن کاملKinetic, equilibrium and thermodynamic studies of cadmium (II) adsorption by modified agricultural wastes.
Agricultural wastes have great potential for the removal of heavy metal ions from aqueous solution. The contamination of water by toxic heavy metals is a worldwide environmental problem. Unlike organic pollutants, the majority of which are susceptible to biological degradation, heavy metals do not degrade into harmless end products. Discharges containing cadmium, in particular, are strictly con...
