Abstract:
The present study is aimed at fundamental understanding of typical lignin bonds cleavage by hydrotreatment over several commercially available catalysts. The study is based on determination of kinetic parameters and relationship between structure and activity of catalysts. In this regard, several dimer model compounds have been used to mimic parts of lignin structure allowing system simplification and therefore forming a clearer picture of creaking mechanism. Micro-kinetic model has been applied to determine adsorption, desorption and reaction rate constants and activation energies. Model takes into account hydrogen dissolution in the solvent (hexadecane), transport phenomena, surface reactions, type and amount of active sites enabling a comprehensive system description.
