Abstract: There is provided a process for converting methanol or dimethyl ether to a product containing C2 to C4 olefins, which comprises the step of contacting a feed containing methanol or dimethyl ether with a catalyst which comprises a zeolite having 10-ring intersecting channels, such as ZSM-5, and which has a Diffusion Parameter for 2,2-dimethylbutane of less than 100 sec-1 when measured at a temperature of 120 °C and a 2,2-dimethylbutane pressure of 60 torr (8 kPa). The contacting step is conducted at a temperature of 370 to 480 °C, a methanol partial pressure of 30 to 150 psia and a methanol conversion per pass of less than 95 %.
