In order to obtain biofuel by catalytic hydroconversion of waste soybean oil, we
studied the effect of manganese addition to NiMo/ Al 2 O 3 catalysts.
Al 2 O 3 and Al 2 O 3 -MnO1 supports were synthetized and characterized by nitrogen
adsorption and zeta potential. Al 2 O 3 support has a A BET of 385 m 2 /g and a net
surface pH of 8.8. Whereas Al 2 O 3 -MnO1 support present a A BET of 317 m 2 /g and
a net surface pH of 8.7.
Raman and diffuse reflectance UV-Vis spectroscopies results of NiMo/Al 2 O 3 and
NiMo/Al 2 O 3 -MnO1 catalysts showed Ni 2+ (O h ) and Mo 7 O 24
2-
species in both
catalyst.
Catalysts were evaluated in the hydroconversion of new and waste soybean oil
with a pressure of 40 bar and a temperature of 380 - 410 °C. The oil
hydroconversion products were analyzed by infrared spectroscopy and gas
chromatography. Commercial NiMo conversion were 14.7% for new oil and
23.7% for waste oil, respectively. On the other hand, NiMo/Al 2 O 3 catalyst
conversion were 19.6% for new oil and 21.3% for waste oil. The selectivity results
show that the NiMo/Al 2 O 3 catalyst produce more hydrodeoxygenation products
(S C18 / C17 =0.16) than the commercial NiMo catalyst (S C18 / C17 =0.08).
