Cracking good cracking : Mesoporous ZSM‐5 zeolite catalysts (see TEM image) made by soft templating methods show higher gas–oil cracking activity and greatly enhanced product selectivity than conventional ZSM‐5. The cracking of large hydrocarbons to gasoline and diesel fuel occurs in intracrystal mesopores, while the conversion of smaller molecules into feedstock olefins occurs in framework micropores.
