From the H that catalyst reactor 18 is made to provide continual and steady, most appropriate flow-rate ratio2With CO gases.
The present invention is with from the thermal decomposition gas of 4 inner generation of thermal decomposition furnace, only to H2Selective Separation is carried out with CO, by this
After a little gases are temporarily stored within respective holding vessel respectively, H is controlled2With quantity relative ratio relationships of the CO in catalyst reactor 18, synthesis
Unthickened fuel.
By O2It blows into thermal decomposition furnace 4 as oxygen source, O2To be detached from air, after air separation, residue is isolated
The N come2Storage to N2 holding vessels 3 are recycled.
In the present invention, in order to remove the H contained in thermal decomposition2O and asphalt component, using allowing, thermal decomposition gas and water are direct
Contact, the processing for being cooled down and being cleaned.
The application is included in the thermal decomposition gas after cleaning, to H2And the gas separator that CO is separately separated.For
Make the H being stored in each holding vessel2And CO is supplied to catalyst reactor 18 with optimal flow-rate ratio, sets the stream of each gas
Gauge and make H2With the flow of CO ensure the adjusting control device of the ratio of certain numerical value and the flow control valve of each gas into
Row controls to adjust.
Due to isolating H from gas separator2With the CO in residual gas after CO2, therefore be further provided with to CO2
Detached and stored the CO2The device of gas.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
