As a significant by-product of coal pyrolysis processes, tar is rich in polycyclic aromatic hydrocarbons (PAHs), garnering considerable attention for their potential conversion into high-value products through saturation hydrogenation. This paper presents comprehensive review recent advancements two key areas: progress high-activity saturated hydrogenation PAHs catalyzed by precious metals and the regulation cis–trans isomeric configuration products. Furthermore, investigation addresses critical challenges involved field: susceptibility metal catalysts to sulfur poisoning during tar’s difficulty controlling stereo-isomerization will advance fundamental understanding mechanisms provide technical guidance utilization, supporting sustainable development clean energy technologies chemical production from by-products.
