Abstract: To expand the sources of heavy naphtha raw materials and achieve the high-value utilization of low-quality diesel, the process conditions and product distribution patterns for hydrogenation cracking of distillate diesel mixed with fluidized bed diesel to produce heavy naphtha were systematically studied. By comparing the two operation modes of "constant reaction depth" and "constant reaction temperature", the influence of the blending ratio of fluidized bed diesel (10% - 50%) on the properties of raw materials, process conditions, product distribution and product quality was investigated. The results showed that fluidized bed diesel was rich in nitrogen compounds and polycyclic aromatic hydrocarbons. As the blending ratio increased, the density of the mixed raw materials rose, the total nitrogen content significantly increased, and the processing difficulty significantly increased. Under the condition of constant reaction depth, moderately increasing the reaction temperature could effectively maintain the stable yield of heavy naphtha, and the mass fraction of cycloalkanes and aromatics (N + A) increased from 33.30% to 39.50%; while under the condition of constant reaction temperature, high blending ratio led to insufficient denitration, a significant decrease in the yield of light/heavy naphtha, and a sharp increase in the yield of unconverted oil, indicating that the reaction depth was seriously insufficient. Controlling the blending ratio of fluidized bed diesel to be between 30% - 40% and matching it with corresponding strictness, could ensure the conversion efficiency and improve the quality of heavy naphtha.
