連続式攪拌槽型反応器によるポリプロピレンの熱分解

抄録

For the purpose of converting the disposed polypropylene to fuel oil or chemical feed stocks, the experimental work on thermal degradation of polypropylene was carried out by using a CSTR under the pressure of 1-8 atm, at 390°C.
The following results were obtained.
1) The pressure has a marked effect on the rate of thermal degradation of polypropylene. The degradation rate decreases to three fifth with the pressure elevation of 1 to 8atm.
2) The molecular weight of gaseous product, liquid product and reactor content decrease with the elevation of the degradation pressure, respectively.
3) The higher pressure diminishes the foaming phenomena in the reactor and makes the operation of CSTR more stable.
