PROCESS FOR CONVERTING METHANOL INTO OLEFINS Abstract In the conversion of methanol into ethylene, methanol is catalytically dehydrated and the ether product is converted into olefins at predetermined conversion over a zeolite catalyst. The zeolite catalyst is arranged as a plurality of beds with alternate cooling zones. The temperature rise in each bed is not greater than the methanol to ethylene sensitivity parameter and each cooling zone reduces the temperature by the same amount. The total number of beds is at least equal to the ratio of total adiabatic temperature increase at the predetermined conversion to the sensitivity parameter.
