The La₍₁₀₎zeo₍₉₀₎ catalyst showed a conversion of OA up to 99 % with 83 % C₁₅ and C₁₇ selectivity after the reaction at 350 °C for 2 h under 4 MPa H₂ pressure. The superior activity of La₍₁₀₎zeo₍₉₀₎ was attributed to the synergistic interaction between La-Si-Al, a sufficient amount of weak + medium acid sites and excellent textural properties (large pore diameter). Larger pore diameter of La₍₁₀₎zeo₍₉₀₎ is highly desirable as it will generate greater diffusion of bulky molecules, thereby improving the accessibility of the reactant and hence excellent catalytic activity. The vacuum distillation was used to purify the crude liquid product (CLP), producing high-quality diesel fractions mainly comprising C₁₄, C₁₅, and C₁₇ fractions.]]> Mon 29 Jan 2024 18:39:08 AEDT ]]>
