Abstract

In the production of low-molecular olefins, in particular of ethylene and propylene, an educt stream (O) containing at least one oxygenate and an educt stream (C) containing at least one C4+olefin are simultaneously converted in at least one identical reactor on an identical catalyst to obtain a product mixture (P) comprising low-molecular olefins and gasoline hydrocarbons. The ratio (V) of oxygenates in the educt stream (O) to C4+ olefins in the educt stream (C) here is 0.05 to 0.5 and is calculated according to the following formula:with:
