Nitric acid is prepared by the combustion of ammonia with oxygen or gases containing oxygen under normal pressure, the resulting nitrogen oxides being compressed, after leaving the combustion elements, to a pressure of several atmospheres in a turbo-compressor and converted under this pressure into ...
摘要: PROBLEM TO BE SOLVED: To provide a method for producing nitric acid with which the optimization of nitric acid production is attained under the improvement of production parameters and material- and energy balance at the time of averting or reducing the drawback of the prior art.收藏...
Low Temperature Selective Catalytic Reduction of Nitrogen Oxides in Production of Nitric Acid by the Use of Liquid Ammonia This paper presents the application of low-temperature selective catalytic reduction of nitrous oxides in the tail gas of the dual-pressure process of nitr... N Zečević,M...

The dual injection of oxygen into the ammonia reaction mixture and into the nitric oxide oxidizing step, together with the use of the inert cooling fluid in the ammonia reaction mixture, has been found to provide increased nitric acid production while allowing one to respect the constraints of ...
An improved process for either the manufacturing of nitric acid, recycling nitric acid, or recovering of nitric acid, comprising the steps of: providing a source of NOx; reacting one mole NO from the source of NOx with one mole of HNO3 in the presence of NO2<-> to produce a resulting ...
However, the contribution of the recently discovered ammonia-oxidizing archaea (AOA) to N2O production from soil is unclear as is the mechanism by which they produce it. Here we investigate the potential of Nitrososphaera viennensis, the first pure culture of AOA from soil, to produce N2O and ...
