1. When Al_2O_3･Pt mixture containing ca 1% Pt in it was used as a catalyst, the maximum conversion efficiency was 35.8% and it was assumed that by reference to the experimental results already performed on the ammonia oxidation process Pt-content in the mixture had to be increased up to 5% at least.　2. When wire gauze made of Pt･Rh alloy containing 13% Rh in it was used, there was no distinct difference observed on catalytic activity, compared with pure platinum and about 8 hours were required to activate the catalyst.　The suitable number of sheets of wire gauze was 1-2 and in the case of 4 sheets bad results were obtained owing to the occurence of side reactions or consecutive reactions.　3. The optimum flow-rate was 21/min.cm^2 for the use of 1-2 sheets of either Pt･Rh alloy or pure Pt catalyst, and the more sheets are used, the higher the flow-rate will be.　4. The concentration of HCN in the product gas was ca 6%, under the most favorable condition, either for Pt･Rh alloy catalyst or pure Pt catalyst.
