ABSTRACT:
A process for the catalytic decomposition of chlorofluoro-alkanes commonly named as "flons" into harmless substances against destructing ozone layer of the stratosphere by using the catalyst comprising alumina or alumina -silica complexed oxide, wherein the range of Al/(Al+Si)atomic ratio is 1.0 to 0.5, in the presence of steam at the temperature of 350.degree. to 1.000.degree. C.
