This paper considers possible uses of fruit-based waste for the production of valuable chemicals
and biofuel precursors through recycling by thermochemical conversion. Slow pyrolysis of goji
berry mesocarp as sugar-riched feedstock was investigated using simultaneous thermal analysis
measurements in non-isothermal conditions. This work announced that pyrolysis of goji berry
mesocarp represents a promising route to obtaining an important key platform chemical - 5-
hydroxymethylfurfural (5-HMF). To establish the process mechanism, two kinetic approaches
were used for kinetic parameters determination: first, Friedman’s and Vyazovkin’s model-free
(inverse) methods supported by numerical optimization of the process, and second, the modelbased
(direct) method. Model-free results showed a complex evolution of activation energy with
conversion, indicating a multi-step mechanism. It was found that autocatalytic dehydration of
fructose (in the presence of Lewis acids) is responsible fo...r the production of 5-HMF at a low
heating rate (5.0 K/min) with a maximum 5-HMF theoretical yield of 63.20 %. Higher heating
rates (10.0 K/min and 15.0 K/min) trigger the fructose autogenesis behavior which opens the
transferability channel to glucose (substrate) engagement for 5-HMF theoretical high yield
production. It was revealed that differences between kinetic parameters are a consequence of the
change in the mechanism of glycosidic bond cleavage. The validity of the proposed reaction
mechanism scheme and accuracy of kinetic parameters was confirmed by modulated dynamic
predictions.
