Latest Patents

One of Roos’s patents describes a process for removing sulfur from a gas stream containing sulfur dioxide, hydrogen cyanide, and hydrogen sulfide. The process combines hydrogenation, hydrolysis, ammonia removal, and hydrogen sulfide removal. It uses an aqueous alkaline washing liquid to capture hydrogen sulfide, then regenerates the spent liquid in an oxidation bioreactor using sulfide-oxidizing bacteria.

Another patent, “Process for Gas Incineration,” concerns the incineration of gases containing sulfur compounds. It describes contacting the gases with an oxygen-containing gas in the presence of a catalyst supported on a refractory oxide carrier. The catalyst includes a first metal selected from bismuth, molybdenum, or chromium, and at least one Group IIA metal as a second component.

Career Highlights

Roos’s listed inventions focus on gas treatment technologies, including sulfur removal and catalytic incineration. These processes address different stages of handling sulfur-containing gas streams, from recovering sulfur compounds to treating gases through incineration.
