STUDY ON CO_2 GASIFICATION-KINETICS OF TYPICAL MUNICIPAL SOLID WASTES

Taking CO2 as gasification medium,and varying the temperature from room temperature to 900 ℃,a kinetics study on gasification reaction of single component and multi-component municipal solid waste (MSW)has been carried out,the influence of different heating rate,atmospheric condition,and components upon the CO2 gasigication reaction being analysed,obtaining kinetics parameters of CO2 gasification reaction for MSW,establishing kinetics model of CO2 gasification reaction for MSW.At the same time,a comparison study on activation energy of gasification reaction obtained from Coats-Redfern method in single scanning rate and from identical transform rate method in multi-scanning rate has been carried out.
