摘要
本文在气相流动反应器中采用ZSM-5催化剂对水相选择性加氢生物油进行了催化裂解试验研究。主要考察了反应温度、质量空速、油分压和原料油组分含量对产物产率和选择性的影响。结果表明,选择性加氢生物油转化为石油化工用品(烯烃和芳香烃)的最优工况为:反应温度,600℃;质量空速,11.7 h^(-1);油分压,6693 Pa;油组分含量,12 5%。在此工况下,石油化工用品达到最高碳产率76 0%,其中烯烃57 6%,芳香烃18.4%。烯烃和芳香烃的产率及其主要成分的选择性可以根据市场的需求通过调节反应条件来改变。
Catalytic pyrolysis of selectively hydrogenated water-soluble bio-oil was carried out in a gas flow reactor with ZSM-5 catalyst. The effect of temperature, weight hourly space velocity, oil partial pressure in gas phase and oil content in the feed on product yields and selectivities were studied. The results show that the optimizing conditions for petrochemicals （olefins and aromatics） production were： temperature, 600~C; WHSV, 11.7 h-1, oil partial pressure, 6693 Pa; oil content, 12.5%. The maximum yield of petrochemicals is 76.0%, including 57.6% olefins and 18.4% aromatics. The olefins and aromatics yields and their main components selectivities can be adjusted by changing the reaction conditions according to market requirements.
