    Abstract: PROCESSES AND COMPOSITIONS ARE DESCRIBED FOR THE REMOVAL OF UNDESIRABLE COMPONENTS FROM VAPOROUS EFFLUENTS SUCH AS THE REMOVAL OF ODOROUS AND COMBUSTIBLE COMPONENTS FROM THE EFFLUENT GASES OF COOKING PROCESSES. THE COMPOSITIONS ARE CATALYTIC ADSORBENT SHAPES WHICH ARE MADE UP OF A POROUS MATERIAL CAPABLE OF ADSORBING THE UNDESIRABLES, SUCH AS SILICA, ALUMINA, OTHER NON-COMBUSTIBLE REFRACTORIES OF HIGH SURFACE AREA OR ACTIVATED CARBON, HAVING ONE OR MORE CATALYSTS INTERSPERSED THEREIN. A PROCESS FOR MAKING LOW TEMPERATURE OXIDATION ADSORBENT CATALYSTS IS ALSO DESCRIBED. IN THIS PROCESS A GELFORMING MATERIAL AND A DECOMPOSIBLE CATALYTIC SALT ARE MIXED AND PERMITTED TO SET TO FORM A RIGID STRUCTURE. THE SALT IS THEN DECOMPOSED TO PRODUCE AN ENORMOUS NETWORK OF VOIDS IN THE STRUCTURE, THUS PRODUCING STRONG ADSORPTIVE CHARACTERISTICS.
