Light cycle oil (LCO) is an inexpensive feedstock for the production of high-added-commercial-value-mono-aromatic compounds such as benzene, toluene and xylenes (BTX). To extend the knowledge on the processing of LCO for BTX production, the hydrocracking reaction was studied using a commercial NiMo/Al₂O₃ catalyst, ZSM-5 zeolite and their mechanical mixtures (20/80, 30/70 and 50/50) for processing tetralin as model feedstock in a bench-scale-trickle-bed reactor at 450–500 °C, 3.9–5.9 MPa, 1.3 1/h and H₂/feed volume ratio of 168–267 m³/m³. Accessible, well-dispersed and strong Brönsted acid sites eased the hydrocracking of tetralin to BTX and the metallic hydrogenation functions from nickel–molybdenum catalysts were also required to minimize deactivation. To achieve suitable tetralin conversions (86–95 wt%), high BTX selectivity in the liquid phase (44–70 wt%) and suitable catalytic activities for coke precursor hydrogenation (to reduce deactivation), NiMo/Al₂O₃//ZSM-5 mixtures (50–80 ZSM-5) were employed, which probed to be effective.

轻循环油（LCO）是一种廉价的原料，用于生产高附加值、商业价值的单芳香族化合物，如苯、甲苯和二甲苯（BTX）。为了扩展 LCO 加工用于 BTX 生产的知识，使用商用 NiMo/Al ₂ O ₃催化剂、ZSM-5 沸石及其机械混合物（20/80、30/70 和 50/50）研究了加氢裂化反应。用于在小型滴流床反应器中加工四氢化萘作为模型原料，温度为 450–500 °C、3.9–5.9 MPa、1.3 1/h，H ₂ /进料体积比为 168–267 m ³ /m ³。易接近、分散良好且强的布朗斯台德酸位点有助于将四氢化萘加氢裂化为 BTX，并且还需要镍钼催化剂的金属加氢功能来最大限度地减少失活。为了实现合适的四氢化萘转化率 (86–95 wt%)、液相中的高 BTX 选择性 (44–70 wt%) 以及焦炭前驱体加氢的合适催化活性（以减少失活），NiMo/Al ₂ O ₃ //ZSM使用了-5种混合物（50-80 ZSM-5），经调查证明其有效。
