摘要：

Investigate the effects of Ionic Liquid and metal ions on the swelling and pyrolysis characteristics. The simulation results show that IL can weaken intermolecular hydrogen bond of coal, Magnetic Ionic Liquid has a stronger modification effect after adding Fe ions, and hydrogen bond weakening leads to the improvement of coal swelling degree. After [Bmim]Cl modification, the swelling degree is increased by 17.37% compared with raw coal, and after [Bmim]FeCl4 treatment, the swelling degree is further improved. Ionic liquid swelling also has a better effect on subsequent pyrolysis of coal samples, the modification effect of [Bmim]FeCl4 is more significant, which increases by 6.77%. The swelling of MIL significantly reduces the pyrolysis activation energy of coal and thermochemical reaction temperature. On the one hand, the content of heavy groups in pyrolysis products is reduced, and on the other hand, the target of carbon emission reduction can be achieved.
