Published in 2020 at "Fuel"

DOI: 10.1016/j.fuel.2019.116821

Abstract: Abstract The chemical looping ammonia generation (CLAG) of N-sorption/desorption reactions via Al-based N-carriers for producing ammonia (NH3) (a non-carbon fuel) is thought to be an important alternative to the conventional Haber–Bosh NH3 synthesis technology. However,… read more here.
