Summary
Effective carbon capture and utilization (CCU) strategies are vital. This review details CO2 adsorption mechanisms, capture techniques, and diverse applications like enhanced oil recovery and sustainable polymer production.
Area of Science:
- Environmental Science
- Chemical Engineering
- Materials Science
Background:
- Growing concerns over greenhouse gas emissions necessitate advanced carbon dioxide (CO2) management.
- Post-combustion processes represent a significant source of CO2 emissions requiring effective capture and utilization (CCU) strategies.
Purpose of the Study:
- To provide a comprehensive review of CO2 capture and utilization methods specifically for post-combustion processes.
- To explore the molecular mechanisms of CO2 adsorption and various capture technologies.
- To examine the diverse applications of captured CO2, including enhanced oil recovery, food industry uses, and sustainable polymer production.
Main Methods:
- Review of existing literature on CO2 capture and utilization technologies.
- Analysis of molecular interaction mechanisms for CO2 adsorption (chemical and physical).
- Evaluation of different CO2 capture techniques: absorption, adsorption, membranes, and chemical looping.
- Exploration of CO2 utilization pathways in enhanced oil recovery, food and beverage, and polymer synthesis.
Main Results:
- Detailed discussion of CO2 adsorption mechanisms, including the influence of functional groups and moisture.
- Comparative analysis of various post-combustion CO2 capture methods based on efficiency and applicability.
- Identification of key applications for captured CO2, such as enhanced oil recovery (EOR) with polymer flooding, food preservation, and as a feedstock for sustainable polymers (PEF, PHUUs).
- Highlighting the use of supercritical CO2 in micro-cellular plastic and elastomer production.
Conclusions:
- Carbon capture and utilization from post-combustion sources offers significant environmental and economic opportunities.
- Further development of cost-effective and environmentally friendly CCU solutions is crucial for widespread adoption.
- The reviewed technologies and applications demonstrate the potential of CO2 as a valuable resource rather than solely a waste product.

01:14The Carbon Cycle
40.1K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

01:46The Calvin Benson Cycle
4.8K
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

01:19Carbon Dioxide Transport in the Blood
2.5K
Carbon dioxide (CO2) transport in the blood is critical to human physiology. On average, our body cells produce around 200 mL of CO2 per minute, precisely the quantity expelled by the lungs. This process involves the transportation of CO2 from the tissue cells to the lungs in three primary forms.
Forms of CO2 Transport
1. Dissolved in plasma: A small percentage (7-10%) of CO2 is transported and dissolved directly in the plasma.
2. Carbaminohemoglobin: Just over 20% of CO2 is chemically bound to...

02:14Combustion Energy: A Measure of Stability in Alkanes and Cycloalkanes
6.7K
The low reactivity in alkanes can be attributed to the non-polar nature of C–C and C–H σ bonds. Alkanes, therefore, were initially termed as “paraffins,” derived from the Latin words: parum, meaning “too little,” and affinis, meaning “affinity.”
Alkanes undergo combustion in the presence of excess oxygen and high-temperature conditions to give carbon dioxide and water. A combustion reaction is the energy source in natural gas, liquified...
