Outline of Final Research Achievements |
This study aimed to examine chemical splitting of inorganic chlorides (NaCl, KCl, CaCl2, MgCl2) into HCl and counter cation bonded to solid in 325°C pyrolysis of cellulose. Results of the pyrolysis of cellulose and either of those salts revealed the chemical splitting, catalysis of the salts, more significant catalysis of Ca/Mg salts than Na/K ones. Treatments of cellulose in hot water dissolving either of the salts were also performed. The splitting, as expected, caused reduction of pH (release of proton from cellulose) accelerating cellulose hydrolysis and subsequent formation of levulinic acid, 5-HMF and some others at high selectivity/yield.
