Abstract
A catalytic composition is disclosed, which exhibits an X-ray amorphous oxide with a spinel formula, and crystals of ZnO, CuO, and at least one Group VIB metal oxide, and preferably, at least one acidic oxide of B, P. or Si, as well. The composition is useful in oxidative processes for removing sulfur from gaseous hydrocarbons.
