Coproducing Value-Added Lube Base Oil and Green Diesel from Natural Triglycerides via a Simple Two-Step Process |
| 초록 |
A versatile process for coproducing green diesel and value-added lube base oil from natural triglycerides was developed. The two-step reaction process comprises (i) thermal oligomerization of triglycerides and (ii) catalytic deoxygenation of the oligomerized triglycerides via hydroupgrading. Thermal oligomerization of the triglycerides proceeded at the expense of the C=C bonds within the unsaturated fatty acid units. Thus, the degree of oligomerization was enhanced when the reactant triglycerides contained more unsaturated fatty acid units. The oligomerized triglycerides were subsequently deoxygenated over a Pt-MoOx/TiO2 catalyst, which converted the oligomerized and monomeric fatty acid units into lube base oil (C30−C54) and green diesel (C15−C18) fractions, respectively. The produced lube base oils were completely saturated with very high viscosity indexes (>120) which could meet the specifications of group III lube base oil. |
