Abstract: It is shown that the wave of flameless spotty combustion of ballasted RDX can propagate in a stable manner in a granulated initial mixture. Under certain conditions, flameless combustion of RDX-containing granulated mixtures can proceed in a vibrational or gushing mode. Based on the process of flameless RDX combustion, a method of single-stage synthesis of high-porosity granules containing nano-sized cobalt or iron particles is developed. The synthesized granulated composite material reveals a comparable catalytic activity in hydrocarbon synthesis by the Fischer–Tropsch method. This material differs from the existing analogs by the absence of pyrophoric properties.

Keywords: precursors, iron, cobalt, granules, flameless combustion, nano-sized particles.
