| dc.description.abstract | One of the coal combustion ashes is coal bottom ash. Low rank coal bottom ash can act
as TiO2 catalyst’s support which was calcined at varying temperature, has been created. The low
rank coal bottom ash model was collected from low rank coal which burned in muffle furnace at
800 °C for 2 h. Subsequently, the low rank coal bottom ash was impregnated with titanium(IV)
isopropoxide (Ti(PrO)4) 500 ?mol, and then calcined at variation temperature of 300, 400, 500, 600
and 700 °C. The modified physiochemical property of catalysts were determined UV-vis
spectroscopy, N2 adsorption-desorption and hydrophobicity test. The performances of the catalysts
were tested for styrene oxidation with H2O2 aqueous as oxidant. It is found that the low rank coal
bottom ash was as good catalyst support, whereby TiO2 supported low rank coal bottom ash which
calcined at 400 °C possessed the best catalytic activity with styrene conversion 45% and selectivity
87%. | |
