Abstract
An excellent method of decomposing flon is provided which can decompose flon economically with high decomposition efficiency without necessitating high temperature and high pressure by contacting a gas containing a flon with a catalyst at a condition of a temperature of not less than 200.degree. C. and space velocity of not over than 50,000 (hr.sup.-1).
Claims9
A method of decomposing flon, comprising contacting a gas containing flon with a catalyst at a temperature of 200-700.degree. C. and a space velocity of 2,000 to 50,000 (hr.sup.-1), the catalyst being selected from the group consisting of Rh, Pd, Mn, and Cu and an oxide or oxides thereof.
A method of decomposing flon, comprising contracting a gas containing flon with a catalyst at a temperature of 200-700.degree. C. and a space velocity of 2,000-50,000 (hr.sup.-1), the catalyst consisting of components A and B, the component A being a single oxide of a metal selected from the group consisting of Zr, Ti, and W or a complexed multi oxide of at least two metals selected from the group consisting of Zr, Ti, Al, W and Si, and the component B being a metal or metals selected from the group consisting of Pt, Rh, Pd, Ru, Mn, Cu, Cr, and Fe, and an oxide or oxides thereof.
