With the rising global demand for energy and chemicals, improving the efficiency of existing petroleum conversion processes is becoming increasingly important. Ethylene cracker bottom oil (ECB), a by-product of current petroleum refining, contains high content of sulphur compounds and polycyclic aromatic hydrocarbons (PAHs), making hydrodesulfurization and hydrodearomatization into monocyclic aromatics essential. In the conversion of PAHs to monocyclic aromatics, they are transformed into benzene, toluene, and xylene (BTX) through a sequence of hydrogenation, ring-opening, and dealkylation. Since BTX are fundamental building blocks for industrial chemicals, their production from unused fractions can be a vital process. However, no superior catalyst currently exists, and the design of multifunctional catalysts with a balance of metal-acid properties is critical. Therefore, in this study, we develop a series of NiW/ZSM-5 catalyst and evaluated them for BTX production from real feedstock through desulfurization and hydrogenation. The effect of active metal loading was also investigated.
