Abstract

In one example, a method for converting a first compound into a second compound is provided. The method includes providing the first compound in an entrance of a flow through reactor, wherein the entrance comprises a first catalyst and an oxidant, converting the first compound and the oxidant into the second compound as the first compound and the oxidant contact the first catalyst in the entrance of the flow through reactor while moving towards a tail end of the flow through reactor, and converting the first compound and the oxidant into the second compound via a solid catalyst comprising a white crystalline solid with a titanium content of about 0.5 to about 1.5 weight percent (wt %) in the tail end of the flow through reactor.
