摘要

Abstract

In this study

the pyrolysis and combustion characteristics of sugar tar waste liquid (STWL) affected by different water contents and oxygen concentrations are studied by using a Thermogravimetric analysis

and the kinetic parameters of the pyrolysis and combustion are obtained by the Coats-Redfern integral method. The results show that both the pyrolysis process and the combustion process of the STWLs are divided into two stages under the different water contents and oxygen concentrations. The low and high temperature ranges for pyrolysis and combustion process are below 420℃ and 420—500℃ and below 400℃ and 400 -500℃

respectively. As the water contents increase

the pyrolysis initial temperature

gradually decreases and the comprehensive pyrolysis characteristic index

also decreases for the pyrolysis process. The

increases from 224℃ to 350℃

and the index

decreases from 3.30×10

to 0.811×10

. The combustion ignition temperature

c increases and the comprehensive combustion characteristic index

decreases. When the oxygen concentration increases

the ignition temperature and the burnout temperature remain almost constant

with variations of 3.6% and 2.0%

respectively. Besides

the pyrolysis and combustion process of the STWL obeys the stochastic nucleation and subsequent growth model

i.e.

[-ln(1 -α)

]

. These results are expected to provide some valuable guidance for organic waste liquid incineration treatment.
