Abstract: The present disclosure relates to a method for a simulated moving bed to adsorb and separate polycyclic aromatic hydrocarbons. Zeolite, metal oxide and metal-modified materials are employed as adsorbent. Firstly, diesel oil flows through pre-treatment adsorbent to remove the trace amount of impurities. Secondly, the purified diesel oil flows through the simulated moving bed so that the PAHs can be separated from diesel oil. In this process, the valves are switched periodically, leading to the relative movement of adsorption beds. At the same time, desorbent is pumped into the equipment to wash out PAHs, achieving the continuous adsorption-regeneration operation. Thirdly, simple distillation is employed to separate desorbent from clean diesel oil and PAHs, respectively. Finally, the fractions of clean diesel oil and PAHs can be obtained, respectively. The separated desorbent can be recycled. The PAHs removal rate can reach to 90%.
