2、典型的含氧化合物,綜述了具有代表性的典型含氧化合物呋喃類、酚類、醚類和酯類在NiP催化劑催化下的HDO機(jī)理方面的最新研究進(jìn)展。HDO過程中,含氧化合物在催化劑作用下發(fā)生C~0鍵斷裂,0主要通過加氫一氫解以H0的形式脫除,其脫氧產(chǎn)物較為復(fù)雜。生物油中富含呋喃類和酚類化合物,因需要苛刻的脫氧反應(yīng)條件,它們的脫氧難度最大。今后,需進(jìn)一步深入開展HDO理論研究,探究NizP催化劑催化活性的調(diào)控機(jī)制,制備出性能更加優(yōu)異的HDO催化劑。關(guān)鍵詞:NizP;加氫脫氧;生物油;機(jī)理;含氧化合物;活性相中圖分類號:O643.31;TE624.4文獻(xiàn)
