Abstract

The article uses biological oil as raw material and 3Ni/SAPO-11 as catalyst to prepare biological aviation kerosene by catalytic hydrogenation in a fixed bed reactor, explore the effects of different reaction temperature, pressure and space velocity on the selectivity of C₉-C₁₆, the yield of C₉-C₁₆ and the iso-to-normal ratio in liquid phase products, the optimal reaction conditions were obtained. It is found that under the best conditions, temperature 400 ℃, pressure 1.5 MPa, space velocity 1.9 h^-1, the selectivity of C₉-C₁₆ is 52.79%, the yield of C₉-C₁₆ is 51.48%, and the iso-to-normal ratio is 9.11. A 3Ni/SAPO-11 molecular sieve was used as the carrier, 3Ni/SAPO-11 bifunctional catalyst with three metals （Cu, Fe, Co） were prepared and characterized. Under the optimized reaction conditions, the effects of the addition of different metal promoters on the reaction products were investigated by fixed bed experiments.
