Research Trends of Carbon Dioxide Capture using Ionic Liquids and Aqueous Amine-Ionic Liquids Mixtures

Abstract

Anthropogenic CO₂ emissions has led to global climate change and widely contributed to global warming since its concentration has been increasing over time. It has attracted vast attention worldwide. Currently, the different CO₂ capture technologies available include absorption, solid adsorption and membrane separation. Chemical absorption technology is regarded as the most mature technology and is commercially used in the industry. However, the key challenge is to find the most efficient solvent in capturing CO₂. This paper reviews several types of CO₂ capture technologies and the various factors influencing the CO₂ absorption process, resulting in the development of a novel solvent for CO₂ capture.
