JC-18 is a marine decarbonization solvent independently developed by NENGJING, specifically designed for maritime transport scenarios such as ocean-going cargo ships. Its development fully accounts for the reuse efficiency of engine waste heat and the compact layout requirements of onboard carbon capture systems. By systematically optimizing the kinetic and thermodynamic processes within the carbon capture cycle, JC-18 achieves efficient CO₂ capture during ocean transportation while ensuring stability and reliability for prolonged offshore operations. It provides robust technical support for achieving the carbon reduction targets set by the International Maritime Organization (IMO).
