The course of pyrolysis of a pure microcrystalline cellulose powder (Avicel) was followed by simultaneous mass spectrometry-thermogravimetry at a low heating rate (10 °C/min) in argon. A thermal pretreatment of 2 h at 260 °C had no significant influence on the subsequent decomposition, contradicting the findings of some earlier workers. The addition of inorganic salts (MgCl2, NaCl, FeSO4, and ZnCl2) to the cellulose led to dramatic changes in the product distribution and the overall course of the decomposition process. Some of these changes were interpreted to be due to physical influences of the inorganic salts.
