研究室紹介
Professor In-Sik Nam's research lab specializes in catalytic materials and reaction engineering for automotive exhaust emission control, with a primary focus on selective catalytic reduction (SCR) of nitrogen oxides (NOx) and urea-based SCR processes. The lab investigates the thermal and catalytic decomposition of urea, the deactivation mechanisms of three-way catalysts (TWCs), and the development of kinetic models for monolith reactors used in heavy-duty diesel engines. Their work integrates fundamental kinetic studies with practical applications, emphasizing catalyst durability, metal sintering kinetics, and performance prediction under real-world driving conditions. The lab aims to design efficient, durable, and commercially viable catalytic systems for sustainable transportation technologies.

15The thermal and catalytic decomposition of urea over a fixed-bed flow reactor system has been examined for the selective catalytic reduction (SCR) of NO x from mobile sources. The conversion of urea into NH 3 and HNCO, the two major products from the thermal decomposition of urea, increased with the reaction temperature and the reactor space time. Urea was completely decomposed into NH 3 and HNCO at 350 °C when the residence time was longer than 0.1 s. As the reaction temperature increased to 40
