Abstract
The possibility of converting low-caloric fuels into synthesis gas by their partial oxidation in a moving porous layer of a granular heat carrier is theoretically studied. The process is considered in a new version of the reactor with a counterflow of a solid granular heat carrier and reacting gases. A feature of the reactor is the presence of an additional heat exchanger, where the oxidizer gas is preheated due to the residual heat of the solid heat carrier discharged from the reactor. Theoretically, in the approximation of the absence of heat loss and established thermodynamic equilibrium in the products, the macrokinetic modes of the process are considered depending on the main control parameters: the flow rate of the oxidizer gas, the flow rate of steam, the flow rate of the solid heat carrier, and the fuel composition. A quantitative calculation of the temperature and composition of the products in various combustion modes is carried out for the air-steam conversion of isopropanol and the air conversion of low-caloric pyrolysis gas. It is shown that the scheme under consideration provides a possibility to convert low-caloric gas at a temperature above 1500 K with a chemical efficiency of gasification over 90%.

Notes
Strictly speaking, since isopropanol decomposes at a high temperature, we should use the enthalpy of the decomposition products which reach the combustion zone. In this case, the enthalpy of the pyrolysis reaction will be a term in the heat capacity of isopropanol.
