摘要: 针对目前生物油加氢技术中存在的催化剂易结焦、工艺过程不能连续等问题,采用多相放电反应对生物油进行加氢精制。构建了生物油/固体催化剂/H2的多相放电体系,研究了催化剂类型、工作电压、气体流量、反应时间等条件对精制生物油的加氢脱氧效果的影响。研究结果表明:随着工作电压和气体流量的增大,多相放电催化加氢精制生物油的脱氧率(R)呈现出先增加后减少的趋势;随着反应时间的延长,呈现出先增加后稳定的趋势。在工作电压为22kV,气体流量为60mL/min,反应时间为120min的工艺条件下,脱氧率最高可达41%。与生物原油相比,多相放电催化加氢精制的生物油中醇类、酚类、酮类等物质的含量相对较低,而碳氢类物质显著增多。

Abstract: In order to solve the problems of easy coking of catalysts and uncontinuous process in bio-oil hydrogenation technology, the multiphase discharge reaction technology was adopted to hydrofine the bio-oil. The bio-oil/solid catalyst/H2 multiphase discharge system was constructed. The influence of catalyst effect on the hydrogenation of bio-oil was studied. Then the impacts of the working voltage, gas flow rate and reaction time on the effect of multiphase discharge hydrofining bio-oil in the device were researched. The results showed that with the increase of working voltage and gas flow rate, deoxidization rate(R) of multiphase discharge of hydrofining bio-oil were presented to increase firstly then decrease. With the increase of reaction time, R increased firstly then stabilized at the end. Under the conditions of working voltage 22kV,gas flow rate 60mL/min and reaction time 120min, the deoxidation rate could reach 41%.Compared with the raw bio-oil, the contents of alcohols, phenols, ketones, acids of multiphase discharge hydrofining bio-oil were relatively low, and hydrocarbons increased significantly. The feasibility of using multiphase discharge technique was confirmed.
