Background
In the face of the crisis caused by the continuously worsening greenhouse effect, various countries agree to take measures to reduce the carbon dioxide emission, and China has promised that the carbon emission reaches the peak value in about 2030 years. However, emission control and capture of carbon dioxide (CCS) remains a major challenge for the global environment. Sequestration and sequestration of carbon dioxide has been the focus of efforts and research by researchers, and attempts have been made to introduce a new approach to carbon dioxide utilization for more thorough and efficient carbon capture and sequestration. Research indicates that mineralization is a new direction for utilizing carbon dioxide, and the advantages of environmental protection, low cost and the like attract the research attention of people. Under another serious threat of shortage of fresh water resources, further research on carbon dioxide mineralization is pushed by carbon capture and utilization by seawater. The two are combined, so that not only is the fixed utilization of carbon dioxide realized, but also the utilization of seawater pretreatment or brine waste from a seawater desalination plant can be solved.
Thus by being Mg-rich2+、Ca2+May be another promising approach to the carbon dioxide problem. Especially the use of carbon dioxide by seawater/concentrated seawater is very attractive, since it solves two problems simultaneously, on the one hand CO2On the other hand, the problem of seawater pretreatment or brine waste from a seawater desalination plant can be solved. Especially CO-producing chemical products with high added value, is CO2A new approach to utilization.
Zhao et al examined carbon dioxide in CO under different conditions2The method comprises the steps of-a dissolution equilibrium process in a seawater system, and provides flue gas carbon fixation seawater decalcification process and mechanism research which are enhanced by taking sodium hydroxide as a medium, and then, the carbon fixation decalcification process which takes magnesium oxide, magnesium hydroxide and white mud as an alkali source is examined, wherein the carbon fixation decalcification effect and the economy of the magnesium oxide as the alkali source are the best. G.M.Jose-Luis et al propose to utilize rich calcium and magnesium seawater to capture and utilize CO2In the process, a multistage precipitation method is used, calcium carbonate is separated out in the first-stage precipitation method, and pure magnesium carbonate trihydrate is separated out in the second-stage precipitation method. Y.ZHao et al also propose a two-step precipitation method-using the calcium and magnesium resources in seawater to make CO2The carbonate radical and bicarbonate radical dissolved in sea water are respectively sealed and stored into calcium carbonate and magnesium carbonate salt.
