Method for Increasing Efficiency in Mineral Carbonation Using Furnace Slag as Industrial Byproduct

摘要

Provided is a method for fixing carbon dioxide, the method includding: pulverizing furnace slag; mixing water and the furnace slag such that the furnace slag is present in a concentration of 5~15 parts by weight based on 100 parts by weight of water; adding NaOH to the mixture; and supplying carbon dioxide to the decomposed mixture, and then carrying out a hydrothermal reaction, so that carbon dioxide can be stably fixed; the treatment of the furnace slag can lead to ecofriendly effects; and the use of the furnace slag can lead to production of carbonate minerals as the final product.
