| Abstract: | The in fluence of iron compound catalysts on product yield of Shenmu coal hydropyrolysis was investigated in a fixed-bed reactor. Iron-aluminum composite catalysts and iron-silicon composite catalysts were prepared. The results showed that the addition of catalysts significantly improved the hydropyrolysis conversion rate of Shenmu coal. The catalyst Al/3Fe, Al/3Fe-A and Si/3Fe were favorable for tar generation, and the tar yield was increased by 3.7% on average. The catalysts Fe/3Al, Fe/3Al-A, Fe/3Si and Fe/3Si-A were favorable for gas generation, and the gas yield was increased by 3.7% on average. |
