Abstract: The invention provides a process for preparing olefins, comprising: (a) reacting an oxygenate and/or olefinic feed in a first reactor in the presence of a molecular sieve catalyst to form a first effluent comprising olefins; (b) fractionating at least part of the first effluent into an olefinic product fraction comprising ethylene and propylene and an olefinic product fraction comprising olefins containing 4 or more carbon atoms; (c) subjecting a paraffin-containing hydrocarbon feedstock in a second reactor to a steam cracking process to form a second effluent comprising olefins including butadiene; (d) fractionating the second effluent into an olefinic product fraction comprising ethylene and/or propylene and an olefinic product fraction comprising mono-olefins containing 4 or more carbon atoms; and (e) recycling the olefinic product fraction comprising at least part of the ethylene and/or propylene as obtained in step (d) to the reactor in step (a).
