The work is devoted to kinetic modeling and an elucidation of the mechanism of the catalytic action of processing cellulose to glucose and 5-hydroxymethylfurfural (5-HMF) in the hydrolysis-dehydration reaction. Cellulose depolymerization and transformation of the main process intermediates (cellobiose, glucose, fructose, mannose and 5-HMF) were experimentally studied under hydrothermal conditions in pure water in the presence of a solid sulfonated catalyst based on the carbon material Sibunit® at 180 and 200 °C using batch and flow reactors. The catalyst was developed by the sulfonation of carbon by H2SO4. The data obtained were used to suggest the kinetic scheme of the process including the main intermediates and to determine the reaction constants. Modeling of cellulose hydrolysis-dehydration on the basis of the kinetic scheme showed that the model described the experimental results obtained at a sufficient accuracy
