Catalyst design strategies and research progress for hydrogenation saturation of mixed polycyclic aromatic hydrocarbons
摘要
Abstract
The catalytic hydrogenation of polycyclic aromatic hydrocarbons(PAHs)in coal tar to high-energy-density fuels is an important pathway for achieving clean and efficient utilization of coal resources.However,the efficient conversion of mixed PAHs is hindered by their competitive adsorption and dynamic evolution behavior on catalyst surfaces.A fundamental understanding of the interactions among PAHs in mixtures and their impact on the hydrogenation saturation process is essential for designing high-performance catalysts.This review systematically addresses key catalytic challenges stemming from competitive adsorption and evolving reaction pathways,and summarizes advanced strategies for catalyst design and optimization.These include tailoring active sites to mitigate local environment distortions caused by competitive adsorption,modifying support properties to steer target reactions amid dynamic pathway changes,constructing open hierarchical pore structures and performing surface functionalization to improve macromolecular mass transfer efficiency and inhibit carbon deposition deactivation.The future research directions for hydrogenation saturation catalysts of mixed polycyclic aromatic hydrocarbons are also discussed.关键词
