Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 45 words
A method of producing a catalyst for the decomposition of hydrazine by impregnating alumina with a solution of an iridium (Ir) salt in a solvent and then drying and firing it, characterized in that ethyl alcohol is used as the solvent dissolving the iridium salt.
Claim 2
Dependent Claim 57 words
The method according to claim 1, wherein said alumina is obtained by adding aluminum alkoxide to hexylene glycol (2-methyl-2,4-pentane diol), heating it at a temperature of 101°C to 200°C to form a sol, hydrolyzing the resulting sol to prepare a gel, drying the resulting gel and finally firing it at a temperature of not lower than 750°C.
Claim 3
Dependent Claim 13 words
The method according to claim 1, wherein said iridium salt is iridium chloride.
Claim 4
Dependent Claim 19 words
The method according to claim 1, wherein an amount of iridium carried on said catalyst is 5-30% by weight.
