| Abstract: | The effectiveness factor of catalyst for complete oxidation of benzene was in the range of 0.44-0.97. The effectiveness factor was estimated by the approximation method. The profile of partial pressure of oxygen in the catalyst pore was obtained by numerical solution with explicit Adams-Bashford and implicit Adams-Moulton methods combined together. |
