-Electric furnace
Temperature range:
25°C~1500°C
Heat speed :
Maximum 200°C/min
*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.

Volumetric flow rate : 50000 ft3/min
Assumption :
Ideal gas, 1atm, Iso-thermal reactor, No pressure drop, irreversible reaction
Check the input gas when the concentration of VOCs is 1.2 wt%
② Pseudo - Assumption
Rate determining step = Surface reaction
Almost catalyst reaction is determined by surface reaction
VOCs multi system = Toluene pure system
