CARBON DIOXIDE FIXATION TO CARBONATES

摘要

A high efficiency method or process is provided for converting CO(carbon dioxide) to a mineralised compound. The method provides for the preparation of an aqueous solution of water and coal ash or coal residue which when contacted by CObind or convert the COinto carbonates. The process can be carried out in in situ coal liquefaction mines. This process may be used to convert COin large quantities where the COis in concentrated volumes possibly sourced as a by-product from some process of industry. In another variation of the application of this process COmay be directly captured from the atmosphere utilizing airflow over a contact surface or by spraying of one of the aqueous solutions of this process.
