| Abstract: | A set of laboratory apparatus was established for recovery of styrene monomer from waste polystyrene.The influence of various reaction factors were investigated,such as temperature,pressure,amount of catalyst.On the laboratory condition,the yield of liquid product which contains 55 5% styrene monomer is 97 6%. The economic balance of this process was estimated when amplifying to industrial scale.It shows that higher profit can be attained and waste polystyrene plastics can be reclaimed.The pyrolysis mechanism was also discussed. |
