“…This method is superior in low environmental impact, low regeneration energy, and non-toxic (Lin et al, 2022). The most commonly used amino acids are in the form of sodium and potassium salts such as potassium glycinate, sodium taurate, and others (Chen et al, 2020). However, this method is still under development.…”

The production process in the oil and gas industry, which is a major demand, still plays a huge role in carbon emissions, especially in the refining process. The energy and industrial sectors are responsible for more than 75% of these global CO2 emissions. This condition is an important issue regarding the effort to reduce climate change due to these emissions by implementing CCU. This article aims to examine methods of carbon capture with chemical absorption by solvents and to compose a model diagram of carbon utilization with microalgae. An extensive literature search was conducted in accordance with the scoping review methodology and the PEO framework. Our search criteria were limited to article research within the last 5 years (2017–2021). Themes found from this review included the CCU method in general, carbon capture by solvent method, type of solvent used, advantages and disadvantages, and utilization of carbon in the gas and oil industries. CCU is a model that can be offered as an alternative to reduce CO2 emissions produced by industry. The scoping review result shows the best method for carbon capture is with monoethanolamine (MEA) solvent. The flue gas from post-combustion streams into the absorption column and the solvent is added. The carbon-rich solvent is regenerated by heat to produce a clean solvent to be reused in the capture cycle. Carbon that has been absorbed by the MEA in the form of gas will be channeled through pipes to the microalgae industry as utilization of captured carbon and then converted to biofuels. It was discovered that MEA is a cost-effective solvent, efficiently captures carbon, and can be used repeatedly. However, the amine emissions from MEA are considered hazardous. The conclusion is that MEA solvent has advantages and disadvantages. Further optimization research is needed to determine the preeminent capture and separation process. Thus, it is necessary to determine the best conditions for the use of captured carbon by microalgae.

In the CO2 capture process, solid acid catalysts have been widely adopted to decrease energy consumption in the amine regeneration process owing to abundant acid sites. However, acid sites unavoidably degenerate in the basic amine solution. To address the challenge, nonacid carbon materials including carbon molecular sieves, porous carbon, carbon nanotubes, and graphene are first proposed to catalyze amine regeneration. It is found that carbon materials can significantly increase the CO2 desorption amount by 47.1–72.3% and reduce energy consumption by 32–42%. In 20 stability experiments, CO2 loading was stable with the max difference value of 0.01 mol CO2/mol monoethanolamine (MEA), and no obvious increase in the relative heat duty (the maximum difference is 4%) occurred. The stability of carbon materials is superior to excellent solid acid catalysts, and the desorption performance is comparable. According to the results of theoretical calculation and experimental characterization, the electron-transfer mechanism of nonacid carbon materials is proposed, which is not only beneficial for MEA regeneration but also the probable reason for the stable catalytic activity. Owing to the excellent catalytic performance of carbon nanotube (CNT) in the HCO3 – decomposition, nonacid carbon materials are quite promising to enhance the desorption performance of novel blend amines, which will further reduce the cost of carbon capture in the industry. This study provides a new strategy to develop stable catalysts used for amine energy-efficient regeneration.
