Chemoselective decarboxylation of ceiba oil to diesel-range alkanes over a red mud based catalyst under H-free conditions.

Concerns over global greenhouse gas emissions such as CO and NO as well as the depletion of petroleum fossil resources have motivated humankind to seek an alternative energy source known as green diesel. In this study, green diesel was produced a deoxygenation (DO) reaction of ceiba oil under a H-free atmosphere over Ni modified red mud-based catalysts, which have been synthesized a precipitation - deep-deposition assisted autoclave method. The obtained catalyst was further characterized by XRF, XRD, BET, FTIR, TPD-NH, FESEM, and TGA.

Lewis acid Ni/Al-MCM-41 catalysts for H-free deoxygenation of oil to biofuels.

The activity of mesoporous Al-MCM-41 for deoxygenation of oil (RTO) was enhanced modification with NiO nanoparticles. Deoxygenation at atmospheric pressure and under H free conditions required acid catalysts to ensure the removal of the oxygenated fragments in triglycerides to form liquid hydrocarbons. NiO at different weight loadings was impregnated onto Al-MCM-41 and the changes of Lewis/Brønsted acidity and mesoporosity of the catalysts were investigated.
