ABSTRACT: Feasibility
of dissolution and utilization of expanded polystyrene in cycloalkane solutions
was investigated in this work. The dissolution process of expanded polystyrene
in several cycloalkane solutions decalin, cyclohexane and methyl cyclohexane
was studied. The effect of dissolution temperature, mechanical agitation,
ultrasonic wave and stirring rate was studied under optimized conditions. Mass
transfer coefficients were fitted. The results showed that the dissolution rate
of expanded polystyrene in different cycloalkane solutions was ranked as
decalin > methyl cyclohexane > cyclohexane; higher dissolution
temperature and faster stirring rate could speed up the dissolution of expanded
polystyrene; the effect of mechanical agitation was superior to ultrasonic
condition; the solubility of top face was better than side face and under face.
