“…[47] N 2ðgÞ þ3H 2 Ammonia production using renewable intermittent energy is technically feasible with current technologies. [48,49] Moreover,v arious ammonia-derived nitrogen-based fuels have been previously suggested, such as:A Na nd AN-based compositions, [50][51][52][53][54][55][56] aqueous hydroxylammonium nitrate, [57,58] ammonium dinitramide, [59][60][61][62] and aqueous AN with ammonium hydroxide or urea. [14] While the methanol economy addresses both the energy and the broad chemical sectors, [63,64] …”

“…A MMONIUM nitrate (AN) finds an application not only as a fertilizer and component of industrial explosives, but also as an oxidizer in gas generators and solid rocket propellant compositions [1][2][3], because it is very cheap and generates environmentally friendly combustion products. However, AN-based systems are not free from drawbacks.…”

This paper discusses results obtained by studying a row of progressively complicated ammonium-nitrate-based systems: ammonium nitrate/catalyst, ammonium nitrate/catalyst/hydroxy terminated polybutadiene, ammonium nitrate/catalyst/hydroxy terminated polybutadiene/ammonium perchlorate, and ammonium nitrate/catalyst/hydroxy terminated polybutadiene/ammonium perchlorate/Al. The successive addition of ammonium perchlorate and Al to the binary mixture of a catalyzed ammonium nitrate/binder yields a regular increase in the burning rate, accompanied by a small change in the pressure exponent. On the basis of flame-structure investigation by fine tungsten-rhenium thermocouples, it has been determined that the surface temperature of catalyzed ammonium nitrate as well as ammonium-nitrate-based propellants is controlled by the dissociation reaction of the salt occurring at the surface. An analysis of the results obtained suggests a combustion mechanism of ammonium-nitrate-based propellants, which is based on the leading role of heat release in the condensed phase

“…Hence, the Ref. [35] result is wrong for the present conditions. On the other hand, it is generally accepted that, under low temperature selective catalytic reduction reaction conditions, N 2 O is formed via the decomposition of AN, as an intermediate formed on the catalyst when ammonia reacts with the surface nitrate groups [48][49][50].…”

Nano-composites (Mn2O3, Mn2O3/graphene oxides (GO)) were prepared by a new method. The nano-composites were characterized by XRD and HRTEM. The catalytic performance of the nano-composites on the thermal decomposition of ammonium nitrate(V) (AN) was investigated by TG-DSC and TG-MS. The reaction of AN with the nano-composites in the condensed phase was investigated by RSFTIR. The results of TG-DSC experiments indicated that the nano-composites significantly catalyze the thermal decomposition of AN, especial Mn2O3/GO. The exothermic reaction of AN with Mn2O3/GO commenced at about 185 °C. Based on the TG-MS results, it was ascribed to N2O formation. In the RSFTIR experiments, the dissociation reaction and ionization reaction of AN were both detected. NOx formation at low temperature was also found. NH2 was directly oxidized by HNO3/NO3− at low temperature. The interaction between Mn2O3 and NH3 was detected according to DRIFT experiments. At elevated temperature, the functional groups of GO are destroyed, which had an influence on the interaction between Mn2O3 and GO. A probable mechanism for the exothermic reaction and then its disappearance is proposed. HNO3 gas was absorbed on the surface of solid AN, which can markedly catalyze the thermal decomposition of AN. Perhaps the HNO3 plays a key role in the exothermic reaction and then the reaction of AN disappears at very low temperatures.
