【 摘 要 】

The use of solid adsorbents such as amine-modified silica aerogels to capture CO2 has been commonly used but poses several obstacles, including expensive raw materials, production complexity, and considerations for adsorbent regeneration. This research develops sodium silicate solution as a carbon scrubber in a packed column. Besides being able to capture CO2, the amorphous silica which has economic value can also be produced. The packing size and CO2 flow rate were studied to prevent the deposition of silica inside of the packed column. The precipitated product analysis using XRF, XRD, FTIR, and SEM Image observed that CO2 was well absorbed by sodium silicate solution. The amorphous silica precipitated concentration reaches 98.6%.
