Deoxygenation of m-toluic acid over hierarchical x zeolite

• X zeolite with mesoporosity was obtained using sodium dodecylbenzenesulfonate.
• Deoxygenation of m-toluic acid was achieved over NaX zeolite.
• NaXSDBS was the best zeolite due to the mesoporosity obtained.
• Solvent with low methylation capacity was necessary to obtain toluene.

Catalytic activity of FAU zeolites was tested on the deoxygenation of m-toluic acid at atmospheric pressure and without feeding hydrogen. Sodium dodecylbenzenesulfonate was used as template to obtain a certain mesoporosity in the NaX zeolite. The mesoporosity improved the catalytic activity. This zeolite showed a good activity catalytic increasing the toluene yield to 40%, reducing the oxygen content in the reaction products, and decreasing the esterification reaction. The catalytic activity was kept without deactivation of the catalyst.
