| Abstract: | The intrinsical kineticsal of heavy aromatic transalkylation reactionon FTH-2 catalysts was investigated.The kinetic experiments were carried out under the conditions of excluding the effects of internal and external diffusion to determine the main reaction with variable space velocity experiments.The kinetic model was established,and the ordinary differential equation was used to estimate the parameters.The parameters were optimized by MATLAB programming,and the model parameters were tested.The intrinsical kinetic equations determined for the transalkylation reactions of benzene and heavy aromatics was as follow:$r_{1}=1.3027\times10^{4}exp(-\frac{6.927}{RT})·y^{0.73}_{TIPB}·y^{2.41}_{B}·y^{-0.64}_{IPB}$ |
