Fresh ammonia may be added to the ammonia separated in step (i) for use in the decomposition stage (ii) (b). The process is illustrated by reference to a diagram of a flow scheme (not shown).GUADALUPI,MARIO
Alternative routes to the Haber–Bosch process are being sought to electrify ammonia synthesis. Nitric oxide can be electrocatalytically converted into ammonia, but the Faradaic efficiencies and rates of production are currently far below those needed for industrial application. Here we report a ...
Synthesis of Ru NPs/GaN NWs/Si The deposition of Ru NPs was conducted in a sealed Pyrex chamber equipped with a quartz lid through a simple photo-deposition process. The GaN NWs supported by silicon wafer (~0.5 cm2) was fixed at the bottom of the chamber, and then 50 mL methanol aq...

Electrochemically converting nitrate, a widespread water pollutant, back to valuable ammonia is a green and delocalized route for ammonia synthesis, and can be an appealing and supplementary alternative to the Haber-Bosch process. However, as there are other nitrate reduction pathways present, selectivel...
1. Process for the production of ammonia from a hydrocarbon feedstock comprising the steps of: (a) passing the hydrocarbon feedstock through a reforming section and withdrawing a synthesis gas from said reforming section; (b) passing said synthesis gas through one or more waste heat boilers, with...
