ABSTRACT:
A method of preparing a novel absorption composition comprising zinc oxide, silica and a fluorine-containing acid by mixing a fluorine-containing acid with zinc oxide and silica followed by an agglomeration step. The novel composition, which can be prepared by the novel method, is utilized by contacting a fluid stream with the novel compositin to remove sulfur from the fluid stream. A further embodiment of the method of preparation involves utilizing a technique for spraying a fluorine-containing acid upon a zinc oxide and slica mixture while mixing the mixture by an inclined rotating disk agglomerator.
