Kinetic Modeling of Methanol Transformation into Olefins on a SAPO-34 Catalyst

摘要: A kinetic model for the methanol to olefins (MTO) process on a catalyst based silicoaluminophosphate SAPO-34 has been proposed. The takes into account four individual steps production of ethene, propene, butenes, and remaining hydrocarbons (pentenes + paraffins). parameters have obtained by experimentation in an isothermal fixed-bed reactor, 623−748 K range. In virtue results, it proven that water introduced feed (required attenuation coke deactivation) inhibits olefin formation. This inhibition is taken model.
