Özet
Considerable concern has been aroused to global warming and climate change owing to the effect of greenhouse gases (GHGs) over the last century. Carbon dioxide released mostly from large CO2 emission sources generated by fossil fuels is one of the primary GHG. Carbon capture and storage (CCS) can be a promising approach to capture CO2 from power stations and energy intensive industries and store into the permanent geological formations. The leading technologies for CCS are oxyfuel combustion, pre-combustion and postcombustion which is the most viable method. Solid adsorbents such as zeolites, activated carbon, metallic organic frameworks (MOFs), and amine based adsorbents are currently employed for post-combustion CO2 capture whereas polymeric adsorbents have superior features according to selectivity, capture capacity, thermal stability and ease of modification on the surface of adsorbents. Herein a novel polyacrylamide adsorbent was produced via two different polymerisation methods which are bulk and suspension polymerisation. To synthesise polymeric adsorbents, acrylamide (AAm) as a monomer, ethylene glycol dimethacrylate (EGDMA) as a crosslinker were used, and concentration of monomer and crosslinker was investigated in bulk polymerisation method. Experiments with suspension polymerisation were carried out to examine the effect of stirring speed, initiator type, porogenic solvent amount in the dispersed phase and surfactant amount in mineral oil used as a continuous phase. The morphology of the particles was inspected using scanning electron microscopy (SEM), and the pore size analysis was investigated via ASAP 2020 Micromeritics to observe the porosity of the particles. Thermal analysis of the particles was performed using thermogravimetric analyser (TGA) to examine the stability of the particles. Moreover, Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) were utilised to characterise the particles. The dynamic CO2 adsorption experiments were performed using fixed-bed adsorption column varying with adsorption temperature. Outcomes of the particle characterisation indicated that hyper cross-linked polyacrylamide particles had a porous structure, 0.46 mmol/g of the CO2 capture capacity, and 198 m2 /g of surface area. Furthermore, adsorption temperature has a significant effect on the capture capacity, and it was found that increase in the adsorption temperature decreased the CO2 capture capacity of the particles. Hyper crosslinked porous polymeric particles produced in this work able to be employed as a reliable solid adsorbent rather than other conventional sorbents based on selectivity, CO2 capture capacity, morphology, stability, and durability for the post-combustion CO2 capture according to the results.
