ABSTRACT:
A method is disclosed for decomposing methylene iodide, including the following steps: providing a hydrophobic sorbent zeolite, exposing the zeolite to methylene iodide in the presence of water or water vapor, so that the methylene iodide is adsorbed on the water, heating the zeolite to a first temperature of at least 100.degree. to decompose the methylene iodide, and heating the zeolite to a second temperature of at least 400.degree. to regenerate its sorbent characteristics.
