A review on different methods of CO₂ capture, separation and utilization

Abstract

The increasing threats of global warming and climate change from anthropogenic Carbon dioxide (CO₂) emissions require a fundamental shift to a sustainable and environmentally friendly industry practise. Carbon Capture and Storage can reduce CO₂ emissions (85–90%) from large point emission sources. The proposed review aims at realization of an integrated adsorption unit to capture, recover, and utilize this potentially harmful gas. For successful deployment of Carbon Capture and Storage, it is necessary to develop a cost and energy efficient CO₂ capture and separation method along with the best reactor configuration which can be implemented as per our requirements. Adsorption-based CO₂ capture has enjoyed considerable research attention in recent years. Most of the research efforts focused on sorbent development to reduce the energy penalty. However, the use of suitable gas–solid contacting systems is the key for extracting the full potential from the sorbent to minimize operating and capital costs and accelerate the commercial deployment of the technology. This review paper focuses on CO₂ capture, its separation and utilization. It also focuses on different adsorbent materials with high selectivity and high capture capacity.
