Abstract

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.
