Problems solved by technology
However, the traditional catalytic hydrogenation mainly uses high-pressure reactors for upgrading, and the input cost is too high, the catalyst is easily deactivated, and the reaction time is too long. Therefore, from a long-term perspective, an ideal hydrogenation technology method is urgently needed to replace the traditional method. Refined Bio-Oil

Description
technical field [0001] The invention belongs to the application technical field of low-temperature plasma, and in particular relates to a device for gas-liquid-solid three-phase discharge hydrogenation refining bio-oil. Background technique [0002] Nowadays, with the increasing demand for energy from all walks of life in the world, coupled with the decreasing fossil energy and the serious ecological environment pollution caused by burning, it is urgent for people to explore and develop a clean new energy. Biomass oil extracted from biomass widely present in nature has attracted extensive attention from scholars at home and abroad as a renewable energy source due to its advantages of low nitrogen and sulfur content and zero carbon dioxide emissions. [0003] At present, bio-oil refining and upgrading mainly include catalytic hydrogenation, catalytic cracking, catalytic esterification and emulsification. Compared with other upgrading methods, catalytic hydrogenation can sign...
