Abstract
The invention provides a catalyst comprising iron oxide, nickel, ceria or palladium supported on stainless steel foam. The catalyst is effective in oxidising aromatic compounds such as toluene and o-cresol and, advantageously, is particularly effective when the oxidation is carried out at elevated temperatures that correspond to temperatures attained in areas of the aircraft where cabin air is recirculated.
Claims14
A catalyst comprising iron oxide, nickel, ceria or palladium supported on stainless steel foam.
A method of oxidising a compound of formula (I):
- where R1 is a hydrocarbyl group having from 1 to 5 carbon atoms, —R2 is chosen from —OH, a group of formula (II), (III), or (IV)
- a hydrocarbyl group having from 1 to 5 carbon atoms, —Br, —Cl or —Fl and x is from 0 to 2;
- and wherein said method comprises heating the compound in a gas containing oxygen in the presence of a catalyst comprising iron oxide, nickel, ceria or palladium supported on stainless steel foam.
A method of treating air in an air handling system comprising heating the air in the presence of a catalyst comprising iron oxide, nickel, ceria or palladium supported on stainless steel foam.
