Abstract(Kor)
Abstract(Eng)
Ash remaining after coal combustion was used as a catalyst support for tar steam reforming with various proportions of Al2O3 added for higher reforming efficiency. At a constant Ni content of 12 wt%, a coal ash and Al2O3 were mixed at a ratio of 5:5, 7:3, 9:1. As a result, the catalytic activity for toluene steam reforming was improved by adding Al2O3 at 500-600℃. The catalysts with ratio 7:3 and 5:5 reached toluene conversion of 100% above 700℃. When comparing the catalysts in which the coal ash and Al2O3 mixed at a ratio of 5:5 and 7:3 with the Ni/Al catalyst, it was concluded that this coal ash catalyst has efficient catalytic performance.
