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 .
