Selective Hydrogenation Platform Technology for Fine Chemicals

Fine chemicals are high-value-added chemicals produced by deep processing of basic petrochemical products. approximately 80% of fine chemical production all involve catalytic hydrogenation reactions. China's fine chemical industry is globally leading in scale, but high-end products are scarce, with high import dependence and a lack of independent core hydrogenation technology, severely restricting industrial development. Therefore, developing selective hydrogenation technology for fine chemicals with independent intellectual property rights is particularly important.

CNOOC Tianjin Chemical Research and Design Institute Co., Ltd. (hereinafter referred to as Tianjin Institute), in line with the development trend of the fine chemical industry, has developed a selective hydrogenation platform technology for fine chemicals based on research on the mechanism of selective hydrogenation reactions of different functional groups, the creation of catalytic materials, and innovation in microbubble-enhanced fixed-bed continuous hydrogenation processes.

This technology can be used for relevant process design and the development of supporting catalysts for different fine chemicals, achieving C=C 、 C ≡ C 、 C=O 、-NO₂、- C ≡ N and aromatic rings, etc., the selective hydrogenation of target functional groups, meeting the production needs of high quality and high value of fine chemicals.

II. Advanced Description

The selective hydrogenation platform technology for fine chemicals includes high-performance hydrogenation series catalysts and microbubble-enhanced fixed-bed continuous hydrogenation process 固定床连续加氢工艺， can achieve the functional group high-efficiency directional conversion in fine chemicals. Currently it has been authorized by China 20 invention patents more than published papers 20 more than and won the first prize of CNOOC Technology Invention Award. This technology has been dozens of petrochemical and fine chemical enterprises industrialized application 。

（ 1 ）The catalyst has excellent performance, and the process conditions are mild.

High-performance hydrogenation series catalysts are suitable for C=C 、 C ≡ C 、 C=O 、-NO₂、-C ≡ N aromatic rings, etc. / selective hydrogenation of functional group compounds, with high activity, high selectivity, and high stability. The reaction temperature is lower than that of similar domestic catalysts by 20 ℃ or more, and its performance has reached the international advanced level.

（ 2 ）High-efficiency microbubble-enhanced continuous hydrogenation process

microbubble-enhanced Bubble-enhanced continuous hydrogenation process technology is suitable for gas-liquid or gas-liquid-solid reaction systems, utilizing the energy conversion of high-energy fluids to highly disperse the gas to the micron state making it easier to be captured by the active centers of the catalyst, thus greatly increasing the reaction rate , shortening the single-pass reaction time 20% ; energy saving and consumption reduction, the circulation hydrogen compressor can be cancelled or the hydrogen circulation amount can be reduced; avoiding hot spot generation ， achieving the intrinsic safety of the reaction process.
