Here we report that alkali and alkaline earth metal imides function as nitrogen carriers that mediate ammonia production via a two-step chemical looping process operating under mild conditions. Nitrogen is first fixed through the reduction of N2 by alkali or alkaline earth metal hydrides to form ...
for ammonia production. Techniques to decarbonize hydrogen production are discussed in Section 4.1. 3.3.2 Biomass feedstocks and recycled chemicals Today, petrochemical raw materials are important inputs to the process of making many chemicals. Biomass may be used instead of fossil fuel feedstocks ...
Factors as safety (ammonium nitrite as a salt is explosive above 60 degrees C) and possible side-reactions as formation of ammonia and nitrogen oxides must be carefully evaluated before use in full-scale. Conductivity is a suitable parameter to follow-up the chemical denitrification process. 展开...
Disclosed is a chemical microreactor that provides a means to generate hydrogen fuel from liquid sources such as ammonia, methanol, and butane through steam reforming processes when mixed with an appropriate amount of water. The microreactor contains capillary microchannels with integrated resistive heaters...

(2020). The study concluded that various experimental parameters could influence the functional performance of selective leaching, including types of ammonia salts, leaching and reduction time and temperature, as well as liquid-to-solid (L/S) ratio. Important findings include that ammonium citrate ...
In acidic conditions ammonia, NH3, will convert to more ammonium ion, NH4+. NH3 is highly toxic to fish. Ammonium is safer. But in an alkaline fish tank, less ammonium will exist and will begin to form NH3.You can aerate the tank to help remove excess ammonia. Logged ...
