A one-dimensional pseudohomogeneous model containing a new kinetic scheme for methanol  conversion to hydrocarbons was used to simulate a pilot plant fixed-bed pseudoadiabatic catalytic reactor. A lumped-species kinetic model allowed the evaluation of product distributions under different experimental conditions, while experimentally measured temperature profiles along the reactor were followed closely. Furthermore, the kinetic parameters as calculated from the simulation were in agreement with those obtained in a kinetic study. Simulated concentration profiles inside the reactor showed the role of each kinetic lump and provided a basis for the selection of theoperating conditions required to obtain desired product distributions.
