Abstract
This paper selected gentamicin ferment residue in the tube furnace reactor for rapid pyrolysis experiments, the ferment residue and pyrolysis products (coke, tar) were analyzed by XPS, FTIR and GC-MS. FTIR analysis showed that the ferment residue and pyrolysis products mainly contain saturated alkanes and proteins, sugars and lipids. XPS results show that the pyrolytic coke is mainly C-C chemical bond, its content increased significantly from 55.07% to 72.27%, while the C-N bond from 18.21% to 5.8%. The chemical constituents of the pyrolysis oil were separated and identified by GC-MS. The identified materials could be divided into: aromatic hydrocarbons, phenol and its derivatives, esters, ketones, acids, amines, nitriles and some heterocyclic compounds; The effect of the pyrolysis temperature on the main components of pyrolysis oil was studied. It was found that the effect of temperature on the composition of the components was not significant, but the relative content of the components was significant. At the same time, the nitrogen-containing compounds in the pyrolysis oil are pyrrole, nitriles and indole, and the content is 9.93% -29.17%.
