Catalytic Pyrolyses of Rayon and the Effect on Activated Carbon Fiber
Catalytic Pyrolyses of Rayon and the Effect on Activated Carbon Fiber
摘要
Abstract
The catalytic pyrolyses of rayon have been studied respectively by thermo-gravimetric analysis (TGA) when rayon was treated with phosphoric acid (PA), three ammonium phosphate salts and ammonium sulfate (AS). The air is favorable to the catalysis of dibasic ammonium phosphate (DAP), but not to those of ADP, PA, AP, and AS obviously. It is put forward that a peak's shape character can be described with the ratio of height to half-height-width (H/W/2) of the peak on a differential thermo-gravimetric (DTG) curve. A flat cracking peak, presenting a more moderate dehydration reaction, has a smaller ratio and could lead to higher carbonization and activation yields. The experimental results prove this view. According to expectation, the order of catalysis is: DAP≥ADP＞PA＞AP(>>)AS(>>) no catalyst.关键词
