Preparation of Mesoporous Silica-Supported Palladium Catalysts for Biofuel Upgrade

Abstract

We report the preparation of two hydrocracking catalysts Pd/CoMoO 4 /silica and Pd/CNTs/CoMoO 4 /silica (CNTs, carbon nanotubes). The structure, morphologies, composition, and thermal stability of catalysts were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), and thermogravimetric analysis (TGA). The catalyst activity was measured in a Parr reactor with camelina fatty acid methyl esters (FAMEs) as the feed. The analysis shows that the palladium nanoparticles have been incorporated onto mesoporous silica in Pd/CoMoO 4 /silica or on the CNTs surface in Pd/CNTs/CoMoO 4 /silica catalysts. The different combinations of metals and supports have selective control cracking on heavy hydrocarbons.

Zn-Mo/HZSM-5 Catalyst for Gasoil Range Hydrocarbon Production by Catalytic Hydrocracking of Ceiba pentandra oil

“…The results of the present study revealed that the acid value of Ceiba pentandra oil was 89.49 mg KOH/g. The density (at 20 o C), kinematic viscosity (at 40 o C), and flash point of Ceiba pentandra oil were 0.891 g/cm 3 , 37.47 Cst and 308 o C, respectively.…”

“…Continuous use of fossil fuels creates a negative impact on the environment such as accelerate global warming, CO2 emissions, greenhouse effects and air pollution and other environmental problems [1][2][3][4]. One of the efforts made to overcome the energy crisis is to develop fuel from sources of renewable energy, to develop fuel from new energy sources.…”
