Abstract

Effect of Ni and Fe ions, which were loaded to Loy Yang brown coal by ion-exchange method, on flash hydropyrolysis was investigated, using a bench-scale apparatus. The steam gasification reactivity of the chars prepared from flash hydropy-rolysis of the coals were also investigated using thermo-balance.
The following results were obtained.
1) It was confirmed that Ni and Fe significantly increased the overall carbon con-version in hydropyrolysis of coals. At the same time, they promoted the con-version of liquids and BTX to methane, so it is important for obtaining more li-quids and BTX to select a proper reaction condition.
2) The steam gasification reactivity of the chars prepared from flash hydropyroly-sis of metal loaded coal were remarkbly higher than that of the chars prepared from the original coal.
