| 摘 要： | 在酸性分子筛HZSM-5催化条件下，以玉米秸秆粉为原料，考察了反应温度对热解油品质的影响。在自制流化床热裂解装置上，选取了5种反应温度（450℃、500℃、550℃、600℃及650℃），进行催化热裂解实验，探究热解油含水率、pH和化学组分的变化规律。结果表明：在HZSM-5催化剂作用下，热解油含水率与pH随反应温度线性增加，酸性随着含水率的升高而减弱（pH增大）；热解油中酸类、酚类、酯类及醇类相对含量比酮类、醛类及糖类受反应温度影响更加明显；在HZSM-5催化剂与物料质量比1：10，反应温度为500℃时，热解油品质较好，腐蚀性低、稳定性高，酚类物质种类丰富、相对含量高。研究结果为HZSM-5催化条件下反应温度调控、改善热解油品质提供了一定的科学依据，有利于热解油后续高值化、环保化利用。

| Abstract: | The effect of reaction temperatures on the quality of pyrolysis oil was investigated over acidic HZSM-5 zeolite, using corn stalk powder as raw material. In the self-made fluidized bed pyrolysis device, five reaction temperatures (450℃, 500℃, 550℃, 600℃ and 650℃) were tested in the catalytic pyrolysis experiments to study the moisture content, pH and chemical composition of pyrolysis oil. The results showed that, under the action of HZSM-5 catalyst, the moisture content and pH of pyrolysis oil increased linearly with the reaction temperature, and the acidity decreased with the increase of water content (pH increased); the content of phenols, esters and alcohols was more sensitive than that of ketones, aldehydes and sugars by the reaction temperature; under the conditions of HZSM-5 catalyst and material mass ratio of 1:10, the reaction temperature was 500℃, oil quality was in a good state, corrosive low, high stability, rich phenolic species and high relative content. The results provided a scientific evident that the reaction temperature controlled and improved the quality of pyrolysis oil over HZSM-5 catalyst, which will be beneficial to the subsequent high-value and environmental protection utilization of pyrolysis oil. |
