Carbon capture and sequestration contains a group of technologies keeping thedifferentiation of CO2 from large industrial and energy related sources, transport toa storage location and long-term isolation from the atmosphere. Previous studiesof CO2 adsorption on low-cost iron metal oxide surfaces strongly encourage thepossible use of metal oxide as sorbents, but the tendency of magnetite particles toagglomerate causes a lowering of CO2 sorption capacity. This work investigates theadsorption behavior of CO2 on composite materials prepared coating a low-costcarbonized rice husk (cRH), commercial carbon black (CB) with magnetite fineparticles. The CO2 capture capacity of composites and based on rice husk materialswas evaluated the basis of the breakthrough times measured at atmosphericpressure and room temperature in a lab-scale fixed bed micro-reactor. To thisaim the reactor has been firstly operated for CO2 adsorption data with obtainedsamples.

Co2 Capture Capacity

At present, mitigating carbon emissions from energy production and industrial processes is more relevant than ever to limit climate change. The widespread implementation of carbon capture technologies requires the development of cost-effective and selective adsorbents with high CO2 capture capacity and low thermal recovery. Coal fly ash has been extensively studied as a raw material for the synthesis of low-cost zeolite-like adsorbents for CO2 capture. Laboratory tests for CO2 adsorption onto coal fly ash zeolites (CFAZ) reveal promising results, but detailed computational studies are required to clarify the applicability of these materials as CO2 adsorbents on a pilot and industrial scale. The present study provides results for the validation of a simulation model for the design of adsorption columns for CO2 capture on CFAZ based on the experimental equilibrium and dynamic adsorption on a laboratory scale. The simulations were performed using ProSim DAC dynamic adsorption software to study mass transfer and energy balance in the thermal swing adsorption mode and in the most widely operated adsorption unit configuration.

Monolithic Polymers

Bulk polymerization was used to fabricate molecularly imprinted polymer (MIP) adsorbents inherent with amine-functionality for post combustion CO2 capture. Polymerization was performed at 333 K for 24 hours using methacrylamide and ethylene glycol dimethacrylate (EGDMA) as the functional monomer and cross linker respectively, oxalic acid as the template azobisisobutyronitrile (AIBN) as the initiator and 4:1 (v/v) mixture of acetonitrile and dimethylformamide (DMF) as the porogenic solvent. The monolithic polymers were crushed and ground, followed by screening to 75-215 μm and the template was then removed from the polymeric particles by extraction using methanol and hydrochloric acid (90/10 v/v). A fixed bed adsorption column was used to investigate the performance of the dynamic CO2 uptake capacities. The X-ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared spectroscopy (FT-IR) spectra showed a huge number of -NH2 functionality distributed on the surface of the adsorbents, which thus enhanced the CO2 adsorption uptake. The maximum CO2 capture capacity was found in the MIP with the maximum template concentration (0.40 mmol/g, SBET 258 m2/g at 0.15 bar partial pressure and temperature of 313 K). The MIPs were stable thermally up to 518 K and the isotherms displayed type II revealing a non-uniform distribution of the pore size.

Cobalt dopping Fe-MIL-88B were successfully synthesized -in solvothermal procedure using DMF as solvent and with/without NaOH. The samples were characterized using SEM, BET and TGA techniques. The partly substitution of Fe by Co does not change the octahedral shape of their parent Fe-MIL-88B. Crystallizations conducted in NaOH medium, however, results in rod like with 2-end octahedral shape crystals. The BET specific surface area is 139cm2/g. The TGA data indicated that the presence of Co resulted in an increase in thermal stability of synthesized samples compared to parent Fe-MIL-88B. The CO2 adsorption isotherms in Fe-MIL-88B-Co samples were measured volumetrically at five temperatures:278K, 288K, 298K, 308K, 318K. The obtained results showed that Fe-MIL-88B-Co is a potential adsorbent with a maximum adsortption capacity of 1.2312 mmol/g (at T= 278K). The sample synthesized in alkali medium exhibited a better adsorbent for CO2 storage. Keywords MIL, adsorption, CO2 References [1] S.

Carbon dioxide (CO2) is considered to be the main greenhouse gas contributing to global warming and climate change. Therefore, the present paper investigates the CO2-capture performance of synthesized calcium hydroxides, Ca(OH)2 sorbent at different temperatures which are 350, 450, 550 and 650°C. The CO2 adsorption of the materials synthesized was studied in a thermo-gravimetric analyzer (TGA). The CO2 adsorption temperature strongly influenced the capture performance of the absorbent. The Ca(OH)2 sorbent are prepared by hydrolysis of calcium alkoxides, NaOH as precipitating agent and mixed solvent of ethanol with deionized (DI) water as medium at 35°C. X- ray diffraction (XRD) result showed 40 nm crystallite size of Ca(OH)2 hexagonal crystal structures. The Ca(OH)2 particle size and morphological properties before and after CO2 adsorption are studied by Field Emission Scanning Electron Microscopy (FESEM). The FESEM image indeed showed the rod like shape of Ca(OH)2 structures with rod length increased from 765 to 893 nm while the diameter is between 140 to 160 nm. When Ca(OH)2 sorbent adsorbed CO2, the structures are rigid interconnected each others like a lump shaped. The prepared Ca(OH)2 sorbent possesses a great potential to capture CO2 when increased temperature. Nevertheless, at intermediate temperatures (350-450°C), Ca(OH)2 sorbent still demonstrates a higher CO2 capture capacity than other intermediate temperature adsorbents such as layered double hydroxides (LDHs), lithium zirconates (LiZrO3) and hydrotalcites.

Carbon dioxide capture from cement plant flue gas can play an important role in mitigating CO2 emission that lead to climate change. Among all the technologies evaluated, membranes have potential to be one of the most energy-efficient and low-cost CO2 capture option. In this work, a novel membrane technology, Facilitated Transport Membranes (FTMs), is assessed to further reduce energy demand and cost for CO2 capture in a cement plant. A new process that employs FTMs is simulated and applied to a real clinker production plant in Italy (Colacem, Gubbio). The process is then compared with other carbon capture technologies. Results show that the FTM technology can be competitive with other technologies despite the need of steam to operate the membrane. Despite the benefit in terms of specific emission compared to more established absorption with liquid amines process, further improvements on membrane performances are needed to gain also an economic advantage for carbon capture in the cement industry.

Integrated Gasification

Integrated Gasification Combined Cycle (IGCC) is believed to be one of the most promising technologies to offer electricity and other de-carbon fuels with carbon capture requirement at a relatively low cost. With the process of carbon dioxide capture, it can also actually meet strict regulations for other pollutants emission. However, the performances can vary depending on what kinds of technologies or processes are used. This paper has developed a model and calculated by using Engineering Equation Solver (EES) program to determine and compare different available technologies and processes. There are four main components in the model: Gasification Island; Gas Cleanup Island; Carbon Dioxide Capture Island and Power Island. Among them, the different options of Gasification Island; and Carbon Dioxide Capture Island are expected to be the most effective factors to influence the performance of the plant. Therefore, different gasification processes are examined in this paper, including Shell, GE (Texaco) and Lurgi. The carbon dioxide capture processes are based on SELEXOL, a physical absorption process, because of the high partial pressure of carbon dioxide in the syngas. A process called “double-absorption” is used for capturing sulfur compounds and carbon dioxide. This paper calculated and compared the net outputs, efficiency penalties for CO2 capture part, and net plant efficiencies for different technologies and processes by using EES program. This model tries to treat the IGCC with carbon dioxide capture part as a whole thermal system, instead of just looking at the capture system alone. Different gasification technologies mentioned above will result in various paths and efficiencies of using steam and waste energy in the system. It will make reasonable use of various waste energies and steams for both mechanical and chemical processes to improve the performance of the plant, and incorporate a CO2 capture system into the design concept of the power plant.
