| description | The rising levels of CO<sub>2</sub> in the atmosphere are causing escalating average global temperatures. The capture of CO<sub>2</sub> by adsorption has been carried out using silica gel type III and prepared activated carbon. The date pits-based activated carbon was synthesized using a tubular furnace by physical activation. The temperature of the sample was increased at 10 °C/min and the biomass was carbonized under N<sub>2</sub> flow maintained continuously for 2 h at 600 °C. The activation was performed with the CO<sub>2</sub> flow maintained constantly for 2 h at 600 °C. The temperature, feed flow and adsorbate volume were the parameters considered for CO<sub>2</sub> adsorption. The success of CO<sub>2</sub> capture was analyzed by CO<sub>2</sub> uptake, efficiency based on column capacity, utilization factors and the mass transfer zone. The massively steep profiles of the breakthrough response of the AC demonstrate the satisfactory exploitation of CO<sub>2</sub> uptake under the conditions of the breakthrough. The SG contributed to a maximal CO<sub>2</sub> uptake of 8.61 mg/g at 298 K and C<sub>o</sub> = 5% with F = 5 lpm. The enhanced CO<sub>2</sub> uptake of 73.1 mg/g was achieved with a column efficiency of 0.94 for the activated carbon produced from date pits at 298 K. The AC demonstrated an improved performance with a decreased mass transfer zone of 1.20 cm with an enhanced utilization factor f = 0.97 at 298 K. This finding suggests that a date pits-based activated carbon is suitable for CO<sub>2</sub> separation by adsorption from the feed mixture. |
