Abstract From the Canadian patent

A gas-liquid reactor comprising an outside containment vessel and an inside reaction vessel rotatably supported within the outside containment vessel. A liquid is conducted into the inside reaction vessel and that vessel is, rotated to force the liquid therein against a wall of the reaction vessel and into a film having a stable and geometrically simple shape. A gas is also conducted into the inside reaction vessel to react with the liquid therein. Because of the stable and simple shape of the liquid the, reactions between the liquid and gasses are relatively easy to analyze mathematically.
