Methods for making higher-octane fuel components from a feed stream of C8+ paraffins, including catalytically cracking the C8+ paraffins using a Zeolite catalyst to produce a reaction product of mid-chain paraffins and olefins and short-chain paraffins and olefins. The reaction product comprises liquid phase paraffins having an increased Octane Value over the feed stream paraffins. The reaction product further comprises a gas phase of short-chain paraffins which are separated from the liquid phase. In embodiments, the short chain olefins are hydrogenated to form mid-chain paraffins and a gas phase containing short-chain paraffins.
