Study on bio-oil upgrading reaction using HZSM-5 under super-critical ethanol and analysis method(HZSM-5催化剂上超临界乙醇中生物油催化提质及检测方法研究)

采用不同硅铝比的HZSM-5催化剂,在不同条件下(超临界、亚超临界、非超临界乙醇)催化提质生物油中的高沸点组分(HBF),应用磷核磁共振(31P-NMR)定量检测了提质前后生物油中醇、酚和羧酸类羟基的质量比(羟基质量/生物油质量)变化,研究和评价了催化剂和超临界条件对生物油催化提质的效果.研究表明,超临界条件有利于生物油中脂肪族羟基的转化,但是不利于非缩合羟基的转化;使用不同酸强度的HZSM-5都能使生物油中的羧基完全转化,增加催化剂的酸强度可以促进脂肪族羟基的转化,而只有酸性较弱的催化剂才能顺利转化非缩合酚羟基....
