A kinetic model of seven lumps has been established which allows the quantification of the product distribution (oxygenates, n-butane, C-2-C-4 olefins, C-2-C-4 paraffins (without n-butane), C-5-C-10 fraction, methane) in the transformation of methanol into hydrocarbons at high temperature (400-550 degrees C) on a HZSM-5 zeolite catalyst (SiO2/Al2O3 = 30) with high acidic strength (>120 kJ (mol of NH3)(-1)) and agglomerated with bentonite and alumina The kinetic model fits well the experimental data obtained in a fixed bed reactor, from small values of space time in which the formation of hydrocarbons is incipient, to a space time of 2 4 (g of catalyst) h (mol CH2)(-1) for a complete conversion of methanol The rise in temperature increases the yield of C-2-C-4 olefins, so that the maximum value (similar to 50%) is obtained at the ceiling temperature for the hydrothermal stability of the HZSM-5 (550 degrees C) and space times between 0 6 and 1 (g of catalyst) h (mol CH2)(-1)
