are the most commonly used for reforming reactions coating of the catalysts support on the fecralloy sheets can be accomplished by many techniques after heating up so as to form the aluminum oxide layer at the surface techniques such as dip coating from a solution of dispersed metal oxide particles or from a slurry which contains the metal oxide particles can be employed alternatively catalyst can be deposited on the fecralloy sheets by spraying the catalytic components onto their surface or by plasma deposition etc the catalyst support is then dried by calcination at elevated temperatures the dispersed metal phase can be added to the support forming solution or slurry of the metal oxide particles or it can be added in a separate step from a solution of the desirable metal salt after the calcination step fig1 b illustrates the heat integrated reformer according to another embodiment of the present invention the integrated combustor steam reformer assembly includes a tubular section defined by a cylindrical wall 10 that separates the combustion zone 15 from the reforming zone 14 the assembly housing 11 acts as the reactor wall and defines an axially extending concentric annular passage in heat transfer relation with.
