In the context of global carbon neutrality efforts, calcium carbide slag has emerged as a promising CO₂ adsorbent due to its high absorption capacity. However, kinetic limitations in carbonation hinder its efficiency. Existing research has explored various additive strategies, yet the application of alcohol-amine compounds in solid-phase calcium carbide slag carbonation remains underexplored. This study aims to evaluate the effects of different additive types (MEA, DEA, TEA, NaHCO₃), dosages, and CO₂ flow rates on the carbonation kinetics and product characteristics of calcium carbide slag.
