“…As a result of their ability to facilitate electron acceptance and donation, transition metal oxides (TMOs) promptly emerged as the catalysts of choice. In particular, several characteristics have contributed to the significance of their presence [7], for example, (i) metal components in TMO can exhibit variable valency or oxidation states; (ii) catalytic activity results from physical contact; the reaction ceases when particles no longer have an oxidizeradditive interface; (iii) gaseous product distribution may be altered by some catalytic agents; (iv) ammonium perchlorate propellant systems often use iron oxides as catalysts, since the ferric-ferrous pair may play a pivotal role in the redox-cycle that drives combustion catalysis by iron compounds; and (v) burn rate depends on catalyst concentration, surface area and state of aggregation.…”

“…Propellants are the mixtures of chemical compounds that produce large volume of gas at controlled, predetermined rates [3]. In the initial years, a composite mixture of carbon (fuel), sulphur (binder) and potassium nitrate (oxidizer) was used in solid propellant rocket motors [7]. During last 60's and early 70's propellants based on either nitrocellulose or on synthetic crosslinked polymeric binders such as polysulphides, polyurethanes or polybutadienes were used.…”

The effects of iron oxides (α-Fe2O3, γ-Fe2O3, Fe3O4 in the different size ranges from micron to nano) on the combustion of composite solid propellants, also known as hydroxyl terminated polybutadiene/aluminium/ammonium perchlorate (HTPB/Al/AP) systems, are thoroughly reviewed in this work. The effect of the oxides of iron in (i) condensed phase; (ii) sub-surface and surface; (iii) premix flame (gas phase); and (iv) final flame (gas phase) in deflagration zone are also critically reviewed. The effect of catalyst on the lower pressure limit (LPL), upper pressure limit (UPL) and ignition delay is also studied as a part of the combustion phases. It is understood that unlike during the combustion of pure ammonium perchlorate, the role of iron oxides starts its influence on binder system degradation, binder-ammonium perchlorate reactions at surface and HClO4 decomposition in gas phase. The role of aluminium is to contribute for larger energies in both primary and diffusion flame zone, the heat generated accelerates the surface reactions further. Another interesting topic is nano-oxides of iron, since nanosize contribute for definite increase in burn rate, but the disadvantage of agglomerations both at mixing level and combustion level needs to be addressed. Several strategies are suggested, with the most significant ones being co-precipitation with ammonium perchlorate and the utilization of dispersion agents.

“…Further applications of chemical engineering are found in the fuel industries [27,28]. In the second half of the 20th century, considerable numbers of chemical engineers have been involved in space exploration, from the design of fuel cells to the manufacture of propellants [29,30]. Looking to the future, it is probable that chemical engineering will provide the solution to at least two of the world's major problems: supply of adequate fresh water in all regions through desalination of seawater and environmental control through prevention of pollution.…”

To understand and quantify the complex interactions in continuous flow reactor systems, detailed mathematical modeling of the underlying physical phenomena is an ideal tool to describe the multi-physics. Similarly, to control the overall operation of continuous flow reactor systems requires detailed mathematical models. This study relates to a thermochemical process for producing hydrogen by the catalytic endothermic reaction of methanol with steam in heat-integrated continuous flow reactor systems. Computational fluid dynamics simulations are conducted to better understand the consumption, generation, and exchange of thermal energy between endothermic and exothermic processes in the reactor. The objective of this study is to gain insight into the fundamental characteristics of heat transfer in heat-integrated continuous flow reactor systems. Particular emphasis is placed on the dependence of heat transfer characteristics on different design factors in various situations. The results indicate that the reactor design suffers from a fundamental limitation resulting from the flow configuration in which a reacting stream flows parallel to a heat transfer surface through which the majority of heat is transferred perpendicular to the direction of fluid flow. Balancing the heat requirements of an endothermic reaction with heat generated by an exothermic reaction flowing parallel to and on the opposite side of a separating plate is extraordinarily difficult since the endothermic reaction is likely to have a very different dependence upon concentration and temperature than the endothermic reaction. Thermally matching the reactions is still further complicated by the inherent temperature gradients that are present along the flow length of the reaction channel. Finally, the operating temperatures of the two reactions must be similar since the separate streams are separated only by the thin separating and heat transfer plate.

SummaryThermal decomposition of ammonium perchlorate (AP) containing different concentrations of a polymeric additive such as polyvinyl pyrrolidone (PVP) has been studied by the technique of differential thermal analysis (DTA). The decomposition products have been identified by means of a mass spectrometer. The results of these two experiments suggest strong interaction between AP and PVP in the solid state.
