Apparatus for combustion has a part for decomposing NO x which contains a catalyst consisting of 2–50 wt.% Ir, 0–20 wt.% Cu, 30–90 wt.% A1 2 O 3, and 0–20 wt.% Y-zeolite. The apparatus prevents air pollution by enabling NO x in combustion gas or air to be decomposed, at a lower temperature, without supplying a reducer, which gives low investment and running costs, and easy maintenance.

Influence of Catalyst Binders on the Acidity and Catalytic

The catalysts bound with APS-and-alumina and APS-and-silica showed the bulk crush strength of more than 300 KPa while the Z(A10, S10) catalyst presented the lowest bulk crush strength of 276 KPa. These results can be attributed to the dense and continuous matrix formed by viscous sintering when APS is used and Z(P15, A5) catalyst showed the highest bulk crush strength of 434 KPa.

An Ir catalyst is claimed which has high crush strength and can be used for hydrazine decomposition for spacecraft and satellite propulsion. Bauxite is contacted with 0.1–10 M acid solution for 10–14 h; the mixture is filtered; the filtered bauxite is thermally treated by contacting with air at 500–700C for 2–6 h, then loaded with Ir from a solution containing IrCl 3, Ir[(NH 3 ) 5

Crush Strength of Catalyst Material Catalyst powder for chemical reactions is often formed into a packed bed and placed into a reactor vessel. In packing the catalyst, the formation of smaller particles, or fines, can occur if the packing pressure exceeds a critical value.
