The catalytic combustion-type carbon dioxide generator technology developed by a professor at CNU and improved through university-industry cooperation has obtained a new technology certification from the Ministry of Agriculture, Food and Rural Affairs.

The catalytic combustion-type carbon dioxide generator developed by Professor Choi Byung-chul (School of Mechanical Engineering) is a product that can increase the yield and quality of crops by supplying CO2 gas (carbon dioxide), which can run short for horticultural crops. It is expected to enhance the photosynthetic effect, boost yieldings, and enhance the quality of crops.

CNU transferred this technology to Daon RS Co., Ltd. (CEO: Jeong Pil-soo) in 2014 and jointly acquired a patent in 2016. Through continuous university-industry cooperation between the two sides, CNU and Daon have improved product performance as well as succeeded in commercializing the technology. The technology obtained the New Technology Certification from the Ministry of Agriculture, Food and Rural Affairs on July 13.

The new technology completely combusts LPG fuel with a catalytic combustion technique to prevent the generation of harmful gases and to avoid damage to crops from high temperatures by enabling low-temperature combustion. In particular, the stability of the catalytic combustor was improved, and the function was expanded to enable connection with IoT and big data by modularizing free connection and sensor expansion.

According to the emission gas test, carbon monoxide, nitrogen oxides, and sulfur oxides all marked less than 1ppm.

Professor Choi said, “This equipment is easy to install and enables the production of high-quality agricultural products, which will greatly contribute to the increase in the profits of small and medium-sized horticultural farms. Exports are also expected as the domestic market has been opened for this new technology and overseas patents are also pending.”
