Decomposition of fluorine containing compounds

摘要

A process for the decomposition and removal of one or more fluorine containing compounds from a first gaseous mixture comprising the one or more fluorine containing compounds and water vapour, which process comprises the stages of: (i) contacting the first gaseous mixture with a catalyst comprising an aluminium based material to produce a second gaseous mixture comprising hydrogen fluoride and carbon oxides; and (ii) removing the hydrogen fluoride from the second gaseous mixture to produce a third gaseous mixture, which is substantially free of hydrogen fluoride.
