Ex-situ catalytic pyrolysis of Quercus mongolica over HZSM-5 and in-line esterification of pyrolysis/catalytic pyrolysis vapors with liquid phase n -butyl alcohol were carried out in a fluidized bed reactor. The ex-situ catalytic pyrolysis over HZSM-5 beads was performed to produce bio-oil containing aromatic hydrocarbons. The temperature of the ex-situ catalytic upgrading reaction was varied from 450 °C to 600 °C, and the maximum aromatic hydrocarbons yield was obtained at 450 °C. The selectivity for aromatic hydrocarbons as a function of catalytic reaction temperature varied depending on aromatic ring number, as the selectivity for mono-aromatic hydrocarbons decreased and that for poly-aromatic hydrocarbons increased with temperature. In-line esterification of the pyrolysis/catalytic pyrolysis vapors with liquid n -butyl alcohol was also carried out, and the GC/MS analysis results showed that the acids, aldehydes and ketones in the bio-oil were converted to esters and acetals.

流化床反应器异位催化热解和在线酯化升级生物油

蒙古栎在 HZSM-5 上的异位催化热解和热解/催化热解蒸气与液相正丁醇的在线酯化在流化床反应器中进行。在 HZSM-5 珠上进行异位催化热解以生产含有芳烃的生物油。异位催化改质反应的温度从450°C变化到600°C，在450°C时获得最大芳烃产率。芳香烃的选择性随催化反应温度的变化取决于芳香环数，因为单芳香烃的选择性随着温度的升高而降低而多芳香烃的选择性增加。
