【摘要】 文章以棉花籽为原料,在高温管式炉内、氮气气氛下研究了不同温度下单一棉花籽热解以及加入一系列氯化物(KCl、CaCl2、ZnCl2、BaCl2、CoCl2)时热解产物分布情况?1-2?。研究结果表明,单一棉花籽热解时,随着温度升高,油收率先升高后降低,在400℃时油收率最高。相同热解条件下添加KCl、CaCl2、ZnCl2和BaCl2后均使油收率增加,而添加CoCl2则使油收率减小。此外,400℃时添加BaCl2所得油收率最高,然后是添加CaCl2和KCl;而温度高于600℃时,添加CaCl2和ZnCl2的油收率要高于添加BaCl2的油收率,且都高于添加KCl时的油收率。此外,通过FT-IR对热解生物油检测发现:加入KCl、CaCl2、ZnCl2和BaCl2使热解油中酚类物质的含量有所降低,有利于提高油的品质。更多还原

【Abstract】 The product distributions during pyrolysis of cotton seed when with or without chlorides are investigated in a tube furnace in nitrogen atmosphere.The result shows that with temperature increasing during pyrolysis of cotton seed,the oil yield firstly increases and then decreases,and the oil yield is the highest when the temperature is 400℃.Adding KCl,CaCl2,ZnCl2 or BaCl2 makes the oil yield increase,while adding CoCl2 makes the oil yiled decrease.At 400℃,the oil yield when adding BaCl2 is the highest,and then is CaCl2 and KCl.However,when the temperature is higher than 600℃,the oil yield when adding CaCl2 or ZnCl2 is higher than that when adding BaCl2,and they are all higher than that when adding KCl.Moreover,the results of FT-IR show that adding KCl、CaCl2、ZnCl2 or BaCl2 all could make the phenols content of oil lower.更多还原
