Abstract
On the basis of micropore formation in carbonaceous materials, the activati on energy for the potassium hydroxide activation of Chinese petroleum coke and coal has been deduced theoretically as dB(0)/dt = A exp(-E(a)is an elem ent of/RT), where is an element of is the formation energy for the metastab le solid formed at the activation temperature. The kinetic parameters (freq uency factor, A, and apparent activation energy, E-a) were calculated from this equation as being 5.319 mg/(g min), 36.51 kJ/mol and 6.64 mg/(g min), 49.46 kJ/mol, respectively, for the two carbonaceous materials studied.
