热解温度对青霉素菌渣热解产物的影响

将青霉素菌渣在400～700℃进行热解,研究了产物中热解炭、热解油及气体的产率,以及热解油的组成变化.实验结果表明:600℃时热解油产率最高,随着温度升高,热解炭的产率降低,气体的产率升高;热解油中含量最高的是含氧化合物,在400℃时质量分数达到最高值69.69％,含氧化合物的含量随着热解温度的升高而降低,酸和醇类是热...

Effect of pyrolysis temperature on pyrolysis products of penicillin waste mycelium

The pyrolysis of penicillin waste mycelium was carried out at 400-700 ℃ to study the yields of pyrolysis carbon,pyrolysis oil and gas in the product,especially the composition change of pyrolysis oil. The experimental results show that：The pyrolysis oil yield reaches the highest at 600 ℃,while the pyrolysis carbon yield decreases and the gas production yield increased with the increase of temperature;The content of oxygenated compounds in pyrolysis oil is the highest with a maximum mass fraction of 69.69% at 400 ℃,and decreases with the increase of pyrolysis temperature;Acids and alcohols are the main oxygenated compounds in pyrolysis oil;The mass fraction of nitrogen-containing compounds increases with the increase of pyrolysis temperature with a maximum value of 30.64% at 700 ℃;Amides,pyridines,indoles,and nitrogen-containing heterocycles are the main nitrogen-containing compounds.
