Abstract
Batch type pyrolysis is the most conventional system.This system has some problems that low thermal efficiency and low
operating rate due to take a considerable amount of time to heat up and cool down the reactor.
Compared to it, our continuous system can keep the high efficiency and high operation rate. And, we use only PE, PP, PS as
feedstock, we can produce high quality oil.
We are proud to announce that our system have been already running without trouble for seven years. In addition, thequality of oil made by plastics feed stocks is very high, so we can control quality of this oil between heavy oil and diesel oil.
Keep utilizing this high quality oil for seven years.

1. Introduction
Batch type pyrolysis is the most conventional system.
This system has some problems that low thermalefficiency and low operation rate due to take aconsiderable amount of time to heat up and cool down
the reactor.

In addition, the quality of oil made by plastics feed stocks
is very high, so we can control quality of this oil between
heavy oil and diesel oil. Keep utilizing this high quality oilfor seven years.

4)Technical description
Figure 2 shows a flow diagram of the fuel production
plant at Environment Technology Ltd. in Gunma
Prefecture. The primary treatment, the reactor
temperature is raised to 400 ℃and thermal
decomposition is performed accordingly.
Mixed plastic containers and packaging from householdwaste are thermally decomposed to produce around 90
wt% of hydrocarbon oil. Typical results are shown in
Table 3.

3. Results and Discussion
We have described our continuous system, it can keep
the high efficiency and high operating rate comperard toconventional system.
Additinally, we can only use PP, PE, PS as materials inthis system. So, we can produce a high quality of oil.
And we can use it for electrical generator in our factory.

4. Conclusions
Compared to conventional system, our continuous
system can keep the high efficiency and high operation
rate.
And, we use only PE, PP, PS as feedstock, we canproduce high quality oil.
We are proud to announce that our system have been
already running without trouble for seven years.
