摘要:
采用双金属(Zn,Al)改性MCM-41催化玉米秸秆与聚丙烯共热解制备芳香烃,并基于旋转床反应器研究玉米秸秆与聚丙烯催化共热解的产物分布。结果表明:催化剂的添加对热解产物的分布影响显著,在质量分数为1%的Zn和3%的Al共改性MCM-41的催化作用下,芳香烃(24.31%)含量最高,含氧化合物(12.37%)含量最低。旋转床催化共热解实验中,随着反应温度(500～800 ℃)的增加,生物油的产率逐渐下降,生物油中烯烃和含氧化合物含量的下降使得芳香烃的含量显著增加。随着催化剂添加量(1:0～1:10)的增加,生物油的产率逐渐减少。热解油中芳香烃的含量显著增加,烯烃和含氧化合物的含量下降。随着转速(0～20 r/min)的增加,生物油的产率呈现先减小后增大的趋势,生物油中芳香烃、烯烃和含氧化合物含量的最值均在15 r/min时获得。
Abstract:
This paper investigates separate pyrolysis of corn stalk(CS)and polypropylene(PP)and co-pyrolysis of CS and PP over Zn-Al co-modified MCM-41 to produce aromatics, and the product distribution of catalytic co-pyrolysis of CS and PP was studied based on a rotating bed reactor. The results showed that the product contents and composition were significantly influenced in the presence of catalysts. Zn and Al showed a certain synergistic effect, under the catalysis of MCM-41 co-modified by Zn with mass fraction of 1% and Al with mass fraction of 3%, and the maximum proportions of aromatics(24.31%)and the minimum production of oxygenated compounds(12.37%)were obtained. In the experiment of catalytic co-pyrolysis of CS and PP in rotating bed, with the increase of pyrolysis temperature(500—800 ℃), the yield of bio-oil decreased gradually. The decrease of olefins and oxygenates in bio-oil significantly increased the content of aromatic hydrocarbons. With the increase of catalyst dosage(1:0—1:10), the yield of bio-oil reduced gradually. The contents of aromatic hydrocarbons in bio-oil increased obviously, while the contents of olefins and oxygenates decreased. With the increase of rotating speed(0—20 r/min), the yield of bio-oil first decreased and then increased. The extreme values of aromatics, olefins, and oxygenates in bio-oil were all obtained at 15 r/min.
