Abstract
The desulfurization of gaseous effluents containing contaminating amounts of objectionable sulfur compounds, typically via the Claus reaction and notably in the presence of oxygen, utilizing a support substrate, e.g., titanium dioxide, having an active catalytic phase deposited thereon, such active catalytic phase being constituted of an electroneutral solid solution having the average composition: A.sub.4.+-.y V.sub.2.+-.x O.sub.9 in which A is a metal other than vanadium, e.g., magnesium, calcium or zinc, 0.ltoreq.x.ltoreq.0.2 and 0.ltoreq.y.ltoreq.0.5.
Claims6
In a process for the catalytic desulfurization of a gaseous feedstream containing contaminating amounts of at least one sulfur compound, the improvement which comprises, desulfurizing the feedstream employing a catalyst having an active catalytic phase deposited on a support substrate, said active catalytic phase comprising an electroneutral solid solution having an average composition:
- A.sub.4.+-.y V.sub.2.+-.x O.sub.9
- in which A is a metal other than vanadium, 0.ltoreq.x .ltoreq.0.2 and 0.ltoreq.y.ltoreq.0.5.
