摘要
近年来随着消费柴汽比的逐年降低,柴油的加工转化备受关注,通过采用拟薄水铝石和分子筛作为催化剂载体,利用等体积浸渍法制备Ni-W加氢裂化催化剂,以劣质、重质柴油为原料,在100 mL加氢评价装置上进行反应活性评价,考察反应温度、反应压力和氢油体积比对催化剂加氢裂化活性的影响。结果表明,反应条件显著影响产品质量。以不同原料考察催化剂适应性,结果表明,在加工不同原料时,该催化剂具有良好的原料油适应性,可用于生产优质的重整原料以及优质柴油调和组分。
With the continuous decline in diesel consumption,diesel processing and transformation has attracted much attention.Ni-Wbimetallic hydrocracking catalysts were prepared by impregnation method using pseudo boehmite and zeolite as carriers.The prepared catalyst was tested in 100 mL hydrogenation reactor using inferior diesel as raw material.Effects of reaction temperature,reaction pressure and hydrogen/oil volume ratio on catalyst performance were investigated.It was found that the quality of naphtha and diesel products was highly sensitive to reaction conditions.Furthermore,the adaptability of the catalyst was testedby various inferiordiesel.The result indicated that the catalyst exhibitedgood adaptability for various feedstocks and could be used to produce high quality reforming feed and diesel blending components.
