A process for producing a catalyst for olefin cracking, the process comprising the steps of providing an MFI-type crystalline silicate catalyst, heating the catalyst in steam to remove aluminium from the crystalline silicate framework and extracting aluminium from the catalyst by contacting the catalyst with a complexing agent for aluminium to remove from pores of the framework aluminium deposited therein during the steaming step thereby to increase the silicon/aluminium atomic ratio of the catalyst; and calcining the catalyst at elevated temperature.
