Hydrogen ammonia from

Membranes are also used to separate gases, for example, the production of N2 and O2 from air and the recovery of hydrogen from ammonia plant purge gas. The working principle is a membrane that is chemically tuned to pass a molecular type.

Below 388 K, two different product distributions in the ammonia oxidation are observed, depending on the surface coverage. At low coverage (catalyst is active), N2 and H2O are selectively produced via stripping of hydrogen from ammonia by oxygen atoms. Moreover, the recombination of OH(a)... 

The first company to produce a successful membrane-based gas-separation process was Permea, now a division of Air Products, which introduced hollow-fme-fiber polysulfone membranes for the separation of hydrogen from ammonia reactor purge gas in 1980. This application was an immediate success the feed gas was clean and free of condensable components that might damage the membranes, and the value of the recovered hydrogen provided short payback times. Within a few years, many ammonia plants worldwide had installed these units. Several hundred hydrogen-separating systems have now been installed by Permea and its competitors.

These bacteria accomplish a nitrosadon (ammonium salts -> nitrites). These bacteria are numerous and beloi to the genera Nitrosomonas (aerobic, widely distributed in the soil of Europe and Asia, ovoid or spherical in shape, able to move in a liquid habitat by means of their flagellae they group themselves in mucilaginous zoogloeae) and Nitro sococcus, (in American soil, always non-mobile). The chimiosynthesis of carbohydrates in the nitrous bacteria consists of a transfer of hydrogen from ammonia to CO2 ...
