A carbonization-activation continuous fluidized bed system and process method

Abstract

The application provides a carbonization-activation continuous fluidized bed system and process method, and belongs to the technical field of porous carbon materials; the process method comprises carbonization, activation stages, oil gas treatment and waste heat recovery steps; the carbonization is that interface treatment silicon dioxide is added into phenolic resin balls to obtain composite phenolic resin balls; the composite phenolic resin balls are added into a carbonization fluidized bed reactor, fluidization carbonization is carried out at 640-660 DEG C under a nitrogen atmosphere for 60-70 minutes, the temperature in the reactor is reduced to 480-500 DEG C, and the produced semicoke is sent into an intermediate bin; the composite phenolic resin balls are continuously added into the carbonization fluidized bed reactor for carbonization, and the above process is kept in a semi-continuous state; the system and the process method can guarantee stable process operation, high yield, high specific surface area of the obtained activated carbon product, large pore volume, high tar cracking conversion rate and low tar content at the outlet.
