Target for the 3 @ 1 5 t/ a ethylene yield, the volume of the catalytic bed and mass of the catalyst needed were calculated. The profile of temperature and distribution of the reaction components in the reactor was analyzed, and the heat balance in the indirect heat exchange sections was calculated. ey words: methanol2to2olefin ( MTO ) ; multi2bed adiabatic reactor; indirect heat exchange; mathematical simulation , MTO ,
