“Carbon dioxide Capture and Sequestration: Materials and Technology Potentials”
Summary The global warming caused by global warming due to industrial development and human activities that have caused the emission of many gases into the atmosphere, including carbon dioxide, which is considered a greenhouse gas. Several technologies have emerged that aim to convert carbon dioxide from its gaseous state to the solid state. It is an effective way to protect the environment and reduce global warming. Refining it from the solid state to the gas can provide us with a new source of carbon dioxide at a relatively low cost. The CO2 capture technology based on the reaction of carbon dioxide and water with sodium carbonate is inexpensive and does not cause environmental impacts. The aim of this study is to test the absorption efficiency of carbon dioxide using Na2CO3 and Ca (OH) 2. The Ca (OH) 2 experiments were performed at room temperature. The results were that with increasing time, the CO2 uptake increased by the flow method. According to Na2CO3 experiments carried out at temperatures of 65 ° C and 85 ° C at different times (0.25, 0.5, 1, 2, 3) hours, the carbonation process begins at 60 ° C, that is, Na2CO3 begins to convert to sodium bicarbonate ((( NaHCO3. The results showed that the absorption of the material at 65 ° C was more efficient than 85 ° C especially at the beginning (at 0.25 hours). The absorption was high at the beginning and then decreased with increasing time over the same temperature. Moreover, the loss was the weight is greater at 85 ° C; increased CO2 absorption was observed when the amount of water was increased. A problem with CO2 leakage was encountered during the experiments, which led to the idea of developing a reaction system ensuring higher efficiency and more accurate CO2 capture results.
