The present disclosure is directed to methods of and catalyst systems for converting natural gasoline liquid (NGL) feed to light olefins. The catalyst systems are capable of catalyzing both catalytic cracking and dehydrogenation processes. The catalyst systems include a metal-substituted zeolite comprising a MFI-type and/or a BEA-type framework comprising 0.5 wt. % to 30 wt. % cerium and/or vanadium atoms based on a total weight of the metal-substituted zeolite. The methods include contacting the NGL feed with the catalyst system in a reactor system, thereby converting a portion of the NGL feed to the light olefins and yielding a product stream comprising the light olefins.
