The development of multifunctional catalysts to selectively produce in one-step processes jet fuels (around C12) and diesel (around C16-C18) from bio-oils (vegetable and especially algal oil) is still a challenge to produce next-generation biofuels. This topic is addressed here by investigating the activity of Ni based catalysts in the methyl palmitate conversion, as model test reaction. The performance of Ni/HBEA (8%wt Ni) catalysts, where mesoporosity was introduced by desilication, were compared with those of mesoporous SBA-15. It is evidenced that desilication allows to introduce selective hydrocracking functionality together with HDO (hydrodeoxygenation), the latter prevailing occurring through hydrogenation of the acid group rather than via hydrodecarboxylation.

Abstract
The development of multifunctional catalysts to selectively produce in one-step processes jet fuels (around C12) and diesel (around C16-C18) from bio-oils (vegetable and especially algal oil) is still a challenge to produce next-generation biofuels. This topic is addressed here by investigating the activity of Ni based catalysts in the methyl palmitate conversion, as model test reaction. The performance of Ni/HBEA (8%wt Ni) catalysts, where mesoporosity was introduced by desilication, were compared with those of mesoporous SBA-15. It is evidenced that desilication allows to introduce selective hydrocracking functionality together with HDO (hydrodeoxygenation), the latter prevailing occurring through hydrogenation of the acid group rather than via hydrodecarboxylation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
