It will be appreciated from fig. 6 that raising with pyrolysis temperature, fuel gas total amount is gradually increased.Except three of the above fuel gas,
Also produce the low carbon number hydrocarbon gas based on propylene, acetylene etc..When temperature is increased to 850 DEG C from 650 DEG C, pyrolysis gas are recyclable
Heat increases to 5194kJ/kg (mud) from 3676kJ/kg (mud).
As shown in Figure 7, extend with pyrolysis time, pyrolytic process is more abundant, and product liquid also can occur secondary pyrolysis,
Fuel gas total amount is increased, but increase tendency gradually slows down.When pyrolysis time reaches 50min, pyrolysis gas can return
Receive heat and reach 4553kJ/kg (mud).Consider production efficiency and heat cost, under the conditions of pyrolytic process is more sufficient,
Pyrolysis time can be shortened.
As shown in Figure 8, pyrolytic behavior is condensed, be separated from water and obtain tar, measures calorific value using high pressure oxygen bomb type calorimeter instrument.
When pyrolysis temperature is increased to 850 DEG C from 650 DEG C, callable tar calorific value is gradually reduced, but it is (dirty to be above 6000kJ/kg
Mud).
