“…The availability of peaks O 2 /N 2 O and NO (m/z = 32 and 44, 30) in MS, a high reaction rate and low temperature range may prove the absence of CO and CO 2 in decomposition reaction of HAN [18,19]. At decomposition of HAN with activated carbon KOH, there is observed the phenomenon of N 2 O and NO 2 ions decreasing.…”

Combustion of hydroxylammonium nitrate (95 wt.% HAN) -water solution in presence of high specific surface area activated carbons is investigated in a constant-pressure bomb within the pressure range of 1-6 MPa. The linear burning rate increased for the system of HAN admixed with activated carbons compared to those of the HAN alone. Moreover, the thermal decomposition of HAN (95 wt.%) -water solution spiked with activated carbons was assessed by DTA -TG method. In the presence of activated carbons, the ability to trigger the decomposition at a lower temperature (86 °C vs 185 °C) was observed. The volatile products formed in the course of thermal decomposition of HAN, spiked with activated carbons were characterized by electron ionization mass spectrometry analysis. Primary products of HAN decomposition: m/z = 33 (NH 2 OH) and m/z = 63 (HNO 3 ), which are further responsible for the formation of secondary products such as N 2 O, NO, HNO 2 , NO 2 , O 2 etc. Significant reduction of NOx emissions during thermal decomposition of HAN (95 wt.%) -water solution was observed (ca. 30%) in presence of activated carbons.

Представлены результаты исследований по инициированию газовых горючих смесей с помощью внешних инициаторов, энерговыделение которых при передаче энергии инициатора к смеси характеризуется конечными (ненулевыми) временными и пространственными масштабами. Обсуждены основные результаты. Показано, что воздействуя на временные и пространственные характеристики вводимой от инициатора энергии можно заметно изменять величину критической энергии E+, необходимой для возбуждения в смеси самоподдерживающихся волн горения и детонации и считающейся основным параметром, по которому оценивается пожаро- и взрывоопасность горючих смесей: чем меньше E+, тем более опасна смесь.

“…Combustion of samples is accompanied by a bright flame with the release of a large amount of orange smoke (nitrogen dioxide). The combustion of HAN is accompanied by the formation of a large volume of gases, consisting mainly of NO, NO 2 and N 2 O [56]. In rocket technology, such substances as HAN are used in gas generators in order to create excess pressure.…”

“…The combustion process occurs in three zones (liquidmixed zone, bubbles and gas-gas). It is assumed that during this process, the activated carbon particles are located inside fuel bubbles, which are formed upon heating of HAN, where a large amount of heat is accumulated due to the chemical reaction of fuel decomposition [56].…”

The article presents the investigation results of the formation and synthesis of nanosized materials which were obtained at the Institute of Combustion Problems, many works have been brought to practical use. Investigations of low-temperature soot formation become the basis of nanomaterial synthesis methods, developed at the Institute for Combustion Problems since 1985. Flame can be considered as a chemical reactor to produce target products. The main feature of the processes based on technological combustion is that the target product is formed as a result of the combustion reaction, occurring spontaneously at high temperatures with a high speed without consuming external energy, i.e. due to its own heat. With the development of nanotechnology, new challenges have emerged in the synthesis of nanomaterials under combustion synthesis conditions. Below is a list of works on nanomaterials synthesis carried out at the Institute: complete scheme of soot formation; energy intensive nanocarbon materials; development and study of perovskite photocatalysts for hydrogen evolution; obtaining carbon fibers by the method of electrospinning; obtaining of biologically soluble membranes based on polymeric nanofibres and hydroxyapatite of calcium; synthesis of nanocarbon sorbents for purification of water from heavy metal ions.
