摘要：A lumped kinetic model for methanol to aromatics (MTA) process was investigated using modified ZSM-5 industrialized catalyst. The deactivation kinetic behavior of MTA was studied by developing a 5-lump kinetic model to describe the product distributions. The feedstock and products are divided into five lumps by simplifying reaction network, including oxygenates (methanol and dimethyl ether), C-1 (CO, CO2, CH4 and H-2), aliphatic hydrocarbons, light aromatics (C-6-C-8) and heavy aromatics (C9+). The catalytic activity was reflected by activity coefficient a. The deactivation model kinetic parameters were estimated using simplex and nonlinear least squares methods. This model can be used to predict key products and their compositions of MTA industrial process.
