摘要:      以ZSM -5 为主体, 加入一定量的自制BCM 沸石, 采用水热合成法合成新型柴油非临氢降凝催化剂, 以催化裂化柴油和常三线馏分油为原料对其反应性能进行评价。结果表明, 本降凝催化剂具有明显的降凝效果, 当反应温度为340 ℃, 空速为1 h -1 时, 凝点降幅为62 ℃左右, 且液体产品收率高, 均在95 %以上。本降凝催化剂生产的柴油十六烷值高, 硫、氮含量低, 凝点低, 基本满足产品调和出厂的质量要求。

Abstract:

     A new catalyst for non -hydrogen - dewaxing was prepared by hydrothermal method , using ZSM -5 as the principal component and then adding self -made BCM zeolites.Its catalytic performance was evaluated using catalytic cracked diesel fuel and AGO NO .3 as feed stock .The results show that catalyst has obviousde -waxing effect.The pour point can be reduced by 62 ℃, and higher liquor yield(>95%)were obtained at the temperature of 340 ℃ and space velocity of 1 h -1 .The diesel oil produced using the catalyst shows higher cetane number index , lower content of sulfur and nitrogen, and lower pour point , can meet the quality requirements of product blending .
