title: A method to minimize the global warming and environmental pollution.
abstract: There has been continuous increase in the level of CO2 in atmosphere. Therefore, it is essential to develop an economical and convenient process to reduce the concentration of CO2 in the atmosphere. In this study, we have proposed an economical and efficient adsorption method to minimize the environmental CO2. A fluidized bed adsorption column was used, fabricated using cast iron sheet. The low prize pyrolyzed biochar prepared from farming biomass (crushed fine powder) was used as an adsorbent to adsorb CO2 from the mixture of air and CO2 (99.5% air and 0.5% CO2). The experimental observation was taken for the % removal of CO2 from the mixture of air and CO2, development of adsorption isotherm and to study the effect of pressure and inlet gas flow rate on the amount of CO2 adsorbed per kg of biochar. The exhausted (CO2 adsorbed) biochar from the fluidized column was tested as a fertilizer for the wheat crop and it has given near about 10% increase in the height of wheat crop within the first 10 days after sowing the wheat seeds. On the basis of this experimentation, we have proposed a hypothetical method, using above mentioned fluidized bed column and biochar as adsorbent to reduce the CO2 concentration in the highly polluted regions.
