The results obtained have shown that, under selected operating conditions, this catalytic system lead to the selective production of a number of compounds that can be used as raw chemicals: hydrogenand light olefins in the gaseous fraction and aromatic hydrocarbons in the liquid products. Moreover, it has been found that cokeis deposited over this system mainly in the form of carbon nanotubes, which opens the possibility of preparing a high added-valueco-product from vegetable oils.
