PROBLEM TO BE SOLVED: To provide a manufacturing method of a ceramic of zeolite and plati num alumina capable of reducing black smoke, carbon monoxide, hydrocarbon, benzene, aldehyde, granular material, etc., in the waste gas by petroleums com bustion. SOLUTION: Two kind materials of natural zeolite ore and the platinum alumina processed in powder are subjected to heating treatment at 800 deg.C for about 3 hr, and these are mixed in the ratio of 75% zeolite and 25% platinum alumina, the mixture is processed in spherical body having 3-5 mm particle size, and the spherical body is at first burned at 500 deg.C for 10 hr, then burned at 800 deg.C for 48 hr. |
