Hierarchical zeolites exhibit enhanced accessibility and diffusion rates, which hinders secondary reactions of the primary cracking products. Ni-containing catalysts show an enhanced dehydrogenation activity as denoted by the increased hydrogen, light olefins and coke production. Important changes were observed in the catalytic activity along time on stream, witha progressive increase in the fraction of aliphatic hydrocarbons. Interestingly, the coke formed over the Ni-containing ZSM-5 samples is in the form of carbon nanotubes, which grow causing a segregation ofthe Ni particle from the zeolite support. This effect is attenuated in the hierarchical zeolites because thesecondary porosity stabilizes the metal particles. In summary, rapeseed oil can be transformed into valuable products (hydrogen, light olefins, aromatic hydrocarbons and carbon nanotubes) by using tailored Ni containing nanocrystalline and hierarchical ZSM-5 zeolites
