Investigations on the Effect of Metal Ions on the Products Obtained From the Pyrolysis of Cellulose

摘要

Investigations on the influence of different metal ions,employed in the form of their chlorides,on the pyrolyzate of microcrystalline cellulose and pulp were performed.Cellulose/metal ion mixtures were pyrolyzed and the volatile reaction products enriched on a cartridge filled with Tenax,followed by GC-MS analysis after thermodesorption of the trapped pyrolysis products.Different metal ions,namely Na~+,Ca~(2+),Mg~(2+) and Fe~(3+) were tested at levels ranging from 0.18-2.2 mM g~(-1).Evaluation of the GC-MS pyrograms revealed that the distribution of the selected 37 pyrolysis products was significantly influenced by both,the type and the concentration of the metal ion added.
