abstract |
The invention relates to a method for stabilizing pyrophoric Ni-Al deep 2 O deep 3 catalysts. The aim of the invention is to find a new method for stabilizing Ni-Al deep 2 O deep 3 catalysts, according to d. stable, storable u. activatable catalysts are produced. The essence d. Invention is d. Ni-Al deep 2 O deep 3 catalysts are treated with inert gas after reduction at least at reduction temperature for a certain time until complete hydrogen desorption; After cooling from 383 to 353K air in d. Inert gas stream dosed until the exhaust gas 1 to 5% by volume of oxygen |
