Since the end of 2018,employed as the research and development director of Nanjing Yanchang Reaction Technology Research Institute Co., Ltd.

Research directions include natural product green development technology; enhanced reaction and fine separation and coupling technology; three wastes resource technology; oil refining, petrochemical, coal chemical, fine chemical, environmental protection and other fields of hydrogenation, oxidation, chlorination, hydration, esters Reactor strengthening technology, etc.

In the field of fine separation technology, the non-equilibrium thermodynamic principles of super floating valve trays (SVTs) as well as design research and development theories and industrial control methods are proposed. More than 150 sets of devices (including self-promotion and promotion by patent-licensed companies) have been promoted and applied to technologies such as mother-child float valve trays, 95-type trays, and diversion trays, which are distributed in petrochemical, coal chemical, pharmaceutical, and new materials. Industries, covering more than 20 provinces and municipalities. There are companies from the United States, Germany, Japan, and Korea, as well as large state-owned enterprises and private small and medium-sized enterprises such as Sinopec, PetroChina and Shenhua. According to incomplete statistics, since 1998, it has cumulatively added more than 40 billion yuan in output value and more than 10 billion yuan in profits and taxes. It has recovered 1.005 million tons of nitrogen oxides from industrial exhaust gas to make nitric acid and recovered from waste liquid. 2.562 million tons of chemical solvents such as butyl acetate, n-butanol, formaldehyde and acetic acid.

In the field of enhanced reaction technology, the theoretical method and technical principle of micro-interface enhanced reaction technology and control methods are proposed. A series of mathematical models for control are established. These models can regulate micro-particles (micro-bubbles or micro-droplets) according to the input energy. Size and number, the size of the multiphase interface, and the mass transfer rate between phases, and then calculate and design the reactor structure based on the input energy, so that the catalyst, material ratio, and operating conditions of the reaction system remain unchanged. Achieve the goal of doubling the reaction efficiency of industrial reactors and greatly reducing energy consumption, material consumption, water consumption, and pollutant emissions. It has solved the core problem of how to manufacture micro-bubbles (micron-scale scale) that has been plagued in this field. The Q-CT and HMIS test methods for micro-bubble systems have been proposed for the first time in the world, and billions of micro-bubble reaction systems have been tested and characterized online; micro-interface enhanced slurry bed (suspension bed or emulsified bed) has been developed. Hydrogenation reactor and oxidation reactor, micro-interface enhanced fixed bed hydrogenation reactor, micro-interface enhanced wet oxidation reactor, Interface strengthening chlorination reactor, micro interface strengthening acid hydrolysis reactor, or hydrated micro interface strengthening esterification reactor and other micro-reaction technology equipment and interface platform, provides hardware support for large-scale industrial application of technology. The expert group composed of academicians of the two academies believes that: This technology has originality and independent intellectual property rights, and a number of key technologies have reached the international advanced level. This is a technology that may bring revolution to the refining industry. Micro-interface mass transfer enhancement technology has been widely used in the fields of hydrogenation of residue oil, co-refining of oil and coal, hydrogenation, oxidation, chlorination, esterification, hydration of petrochemical products, and high-salinity refractory industrial wastewater in wet oxidation and ozonation Promotion and application have produced economic benefits of billions of yuan.
