The Kinetic Parameters of Carbonaceous Materials Activated with Potassium Hydroxide
On the basis of micropore formation in carbonaceous materials, the activation energy for the potassium hydroxide activation of Chinese petroleum coke and coal has been deduced theoretically as dB 0 /dt = A exp(–E a ∈/RT), where ∈ is the formation energy for the metastable solid formed at the activat...

| description | On the basis of micropore formation in carbonaceous materials, the activation energy for the potassium hydroxide activation of Chinese petroleum coke and coal has been deduced theoretically as dB 0 /dt = A exp(–E a ∈/RT), where ∈ is the formation energy for the metastable solid formed at the activation temperature. The kinetic parameters (frequency 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. |
