Description

technical field [0001] The invention relates to a biomass oil catalytic hydrogenation reaction device and a catalytic hydrogenation method thereof, belonging to the fields of energy engineering and chemical engineering. Background technique [0002] As a renewable energy source, biomass can replace petroleum resources to produce liquid fuels and chemicals. Biomass oil is a liquid fuel produced from biomass through fast pyrolysis technology. Biomass oil has a high oxygen content, which makes it poor in thermal stability and low in calorific value. It must be upgraded and modified before it can be converted into high-grade fuel. [0003] Catalytic hydrogenation is a good method in biomass oil upgrading technology. Because it can significantly reduce the oxygen content of biomass oil and increase the energy density, it has attracted extensive attention. [0004] In the process of catalytic hydrogenation of biomass oil, polymerization reaction is easy to occur at high tempera...
