Abstract

A study was carried out on the effect of the nature of the support, composition of the active phase, and heat treatment conditions on the activity of trimetallic Ni‑Co‑Mo catalysts in the hydrotreating of a mixed diesel fraction. Temperature‑programmed desorption was used to show the effect of the amount and strength of the acid sites of the support on the activity of catalysts with the same elemental composition. We established the nickel‑to‑cobalt as well as phosphorus‑to‑molybdenum ratios in these trimetallic hydrotreating catalysts corresponding to the greatest desulfurization and minimum formation of polycyclic aromatic hydrocarbons in the hydrogenate.

三金属催化剂在混合柴油馏分加氢处理中的活性

研究了在混合柴油馏分加氢处理过程中，载体性质、活性相组成和热处理条件对三金属镍-钴-钼催化剂活性的影响。我们使用温度编程解吸法显示了支撑物酸性位点的数量和强度对具有相同元素组成的催化剂活性的影响。我们确定了这些三金属加氢处理催化剂中的镍与钴以及磷与钼的比例，这些比例对应于最大的脱硫效果和最小的加氢产物中多环芳烃的形成。
