Steam Reforming of Hydrocarbons on Noble Metal Catalysts (Part 1)

Abstract

The catalytic activity of Group VIII transition metals except Os for methanesteam reaction under atmospheric pressure at 350∼600°C was investigated. The following activity sequence was obtained: Ru∼Rh>Ni>Ir>Pd∼Pt>>Co∼Fe.Ru and Rh were found to possess high and stable activity over a wide range of steam/methane ratio. The rate of reaction on a Rh-silica catalyst was found to be of the zeroth and 0.5th order with respect to methane and steam, respectively.
