Catalytic hydrogenation device and method for biological oil and derivatives thereof

Abstract

The invention discloses a catalytic hydrogenation method and device for biological oil and derivatives thereof, and relates to the field of catalytic hydrogenation of unstable oxygen-containing compounds. The device specifically comprises a liquid sample injection unit, a low-temperature hydrogenation gas-liquid reactor, a high-temperature hydrogenation gas-liquid reactor, a gas-liquid separator, a pressure controller and a product collection and analysis unit, wherein the liquid sample injection unit firstly injects biological oil or derivatives thereof into the low-temperature hydrogenation reactor under high pressure so as to carry out primary selective hydrogenation, stabilizes the fed material, and injects the biological oil or derivatives thereof into the high-temperature hydrogenation reactor connected with the low-temperature hydrogenation reactor to carry out deep hydrogenation; the hydrogenated products are separated and recycled by the gas-liquid separator; the gas phase product is monitored on line by the analysis unit; and the pressure of the overall system is controlled by the pressure controller. The invention can be used for economically and efficiently hydrogenating unstable oxygen-containing compounds, such as biological oil and derivatives thereof and the like, so as to prepare petrochemical products, thereby effectively relieving the petroleum shortage. In addition, the device disclosed by the invention has the advantage of simple structure, is easy to operate, and is suitable for industrial application.

Description

technical field [0001] The invention discloses a method and a device system for catalytic hydrogenation of bio-oil and its derivatives, and relates to the field of catalytic hydrogenation of unstable oxygen-containing compounds. Background technique [0002] In recent years, the sharp increase in China's demand for energy has led to rising imports of fossil resources, especially oil. The lack of oil resources has become an important factor restricting China's economic development. On the other hand, the problem of environmental pollution caused by the utilization of fossil resources has become increasingly prominent, and has become an urgent problem to be solved in today's society. Therefore, it is of great practical and strategic significance to find renewable, environment-friendly alternative energy sources and reduce dependence on fossil resources to achieve sustainable economic development. [0003] Biomass is the product of photosynthesis, the only source of organic ca...
