This work discusses the issues of thermochemical recovery as a method to improve efficiency of fuel utilization in external heat engines (EHE). The article presents thermodynamic analysis of efficiency of external thermochemical recovery (TCR) upon steam reforming of low alcohols, as well as efficiency of internal TCR upon steam reforming of methane. The issues of selection of catalysts are considered and mathematical simulation of variants of TCR solutions with regard to EHE operating by the Stirilng and Rankine cycle is performed. Variants of technical solutions of catalytic heat exchangers with external, internal and combined heat input are analyzed in thermodynamic cycles of EHE, as well as of internal combustion engines (ICE) with respect to thermochemical recovery. Variants of implementation of external and internal TCR have been studied. It is demonstrated that the most promising variants of heat recovery is the external TCR with application of oxygen-containing compounds as fuels, characterized with low point of conversion into synthesis gas (SG). A mathematical model is developed for numerical analysis of devices for TCR of heat in the combustion products of Rankine engine heater. The influence of working fluids on the cycle efficiency is analyzed, it is demonstrated that the most promising variants are gaseous carbon dioxide and ammonia.
