Isomerization Properties of Pt/SAPO-11 Catalysts for the Production of Bio-Aviation Kerosene

The hydroisomerization of n-alkanes is an important step in the production high-quality bio-aviation kerosene. A SAPO-11 molecular sieve was synthesized using hydrothermal synthesis method, and a 0.5 wt% Pt/SAPO-11 catalyst prepared impregnation method. crystal phase, pore structure, acidity, morphology were characterized via X-ray diffraction, N2 adsorption-desorption, NH3 temperature-programmed desorption, scanning electron microscopy, transmission respectively. performance evaluated with bio-n-hexadecane as model compound. results showed that temperature space velocity had significant effects. Under conditions 340 °C, 1.5 MPa, WHSV = 1.0 h−1, V(H2): V(n-hexadecane) 1000:1, conversion n-hexadecane selectivity i-hexadecane 81.8% 86.5%,
