A method is provided for converting a hydrocarbon feedstock in the naphtha boiling range to light olefins. The method includes contacting the hydrocarbon feedstock with a zeolitic material having a crystal size from 50 to 300 nanometers, having a silica to alumina ratio greater than 200 and where the zeolitic material has a silicalite structure.
