Abstract
Hydrotreating of furfural in order to obtain furan derivatives, components for gasoline was studied on two catalysts Ni-Co-Mo /g-Al2O3 promoted with Ba and respectively Pt-Pd/g-Al2O3. Catalysts characterization where performed by determining the acid strength and textural characteristics. For both catalysts the main reaction products identified are tetrahydrofurfuryl alcohol, methyl tetrahydrofurfuryl ether, furfuryl alcohol and furfuryl methyl ether, the most valuable component for gasoline from the resulting mixture being tetrahydrofurfuryl methyl ether. Catalyst Pt-Pd/g-Al2O3 showed higher activity than catalyst Ni-Co-Mo-Ba /g-Al2O3 on the ranges of parameters studied. The yield in ethers was higher than the yield in alcohols for both catalysts for the parameters range studied and the yield in tetrahydrofurfuryl methyl ether was higher in the case of Pd-Pt catalyst than for Ni-Co-Mo-Ba catalyst.
