A comparative study of the steam reforming of phenol towards H2 production over natural calcite, dolomite and olivine materials
(2010)Pre-calcined (air, 850 °C) naturally occurring calcite, dolomite and olivine materials were studied for phenol steam reforming towards H2 production. The effect of reaction temperature, feed volume flow rate, and hydrogen ...
