Abstract: The present invention provides a process for preparing ethylene and/or propylene, wherein an oxygenate feedstock is contacted with a zeolite-comprising catalyst at a temperature in the range of from 500 to 700° C. to obtain a reactor effluent comprising ethylene and/or propylene and the oxygenate feedstock is contacted with the catalyst in a riser reactor having a reactor wall defining a flow trajectory towards a downstream outlet for reactor effluent, wherein at least oxygenate feedstock and catalyst are provided at one or more upstream inlets of the riser reactor and wherein C5 olefins are admitted to the riser reactor at one or more of locations along the length of the flow trajectory. The invention further provides a reaction system suitable for preparing ethylene and propylene.
