The subject of this thesis is catalytic conversion of non-food, plentiful, and renewable biomass corresponding to cellulose and chitin to chemical compounds. In biorefinery, chemical transformation of polymers to worthy compounds has attracted world wide curiosity for development sustainable societies. First, the present scenario of this scorching study quarter has been summarized good within the normal creation of the thesis, which is helping readers to get to grips with this subject. subsequent, the writer explains high-yielding creation of glucose from cellulose by utilizing an alkali-activated carbon as a catalyst, leading to a yield of glucose as excessive as 88%, that's one of many maximum yields ever stated. The characterization of carbon fabrics has indicated that vulnerable acid websites at the catalyst advertise the response, that is markedly assorted from mentioned catalytic structures that require powerful acids. moreover, the 1st catalytic transformation of chitin with retention of N-acetyl teams has been built. the combo of mechanocatalytic hydrolysis and thermal solvolysis allows the construction of N-acetylated monomers in strong yields of as much as 70%. The catalytic structures proven during this thesis are particular within the fields of either chemistry and chemical engineering, and their excessive efficiencies can give a contribution to eco-friendly and sustainable chemistry sooner or later. in the meantime, mechanistic reviews in line with characterization, thermodynamics, kinetics, and version reactions have additionally been played to bare the jobs of catalysts through the reactions. the consequences should be useful for readers to layout and increase new catalysts and response systems.

They argued that the mesoporous structure of the catalyst led to good mass transfer, resulting in the high catalytic performance. Indeed, Katz et al. revealed that long-chain cello-oligosaccharides rapidly diffused and adsorbed into mesopores of carbon material [142, 143]. , a sulfonated composite of mesoporous silica SBA-15 and Fe3O4 (entries 21 and 22) [144, 145] and sulfonated CoFe2O4-embedded silica (entry 23) [146], were also useful as they were easily separated from a product cocktail by a magnet after the reaction.
