Hydrodeoxygenation of Vegetable Oil in a Trickle Bed Reactor for Renewable Diesel Production
The hydrodeoxygenation of vegetable oil in a trickle
bed reactor for renewable diesel production was observed in this research. Vegetable oil was
represented by triolein. The NiMo/Al2O3 catalyst with a
composition of 6.13% w/w Ni, 12.49% w/w Mo, and 81.33% w/w Al2O3
was used. The reactions took place in the temperature range of 272-327.5°C and pressures of 5 and 15 bar. A trickle bed reactor
of 2.01 cm in diameter and 24 cm in bed length was able to convert triolein
into renewable diesel. C18 hydrocarbons became the dominant reacting
compounds at temperatures above 310°C and a pressure of 15 bar, which reached more than
50% w/w. At 5 bar pressure, fatty acids with stearic acid as the acid with the
highest concentration were the dominant reacting component, reaching more than
60% w/w at temperatures above 280°C. This led to double bond saturation once the
reactants were mixed
