The activated carbon fibers adsorbing toluene were used to perform the electrothermal regeneration experiments by made-self electrothermal regeneration system.Throughout quadratic general rotatable design test,toluene desorption rates and quality were used as two indexes to characterize the influence of desorption temperature,carried gas flow and carbon thickness on electrothermal regeneration effect of activated carbon fiber,and finally the local optimal scheme was obtained,it was while 170℃ of desorption ...
