“…Therefore, appropriate adsorbents must present sufficient adsorption capacity, high CO2 selectivity, adequate density and hardness, low abrasion index, and good stability in moisture conditions. Besides, availability, low cost, and easy of regeneration are key factors to ensure the feasibility of the overall adsorption process (Plaza et al, , 2014Samanta et al, 2012;Lee and Park, 2015;Ben-Mansour et al, 2016).…”

Biomass Waste Carbon Materials as adsorbents for CO2 Capture under Post-Combustion Conditions

et al. 2016

A series of porous carbon materials obtained from biomass waste have been synthesized, with different morphologies and structural properties, and evaluated as potential adsorbents for CO2 capture in post-combustion conditions. These carbon materials present CO2 adsorption capacities, at 25°C and 101.3 kPa, comparable to those obtained by other complex carbon or inorganic materials. Furthermore, CO2 uptakes under these conditions can be well correlated with the narrow micropore volume, derived from the CO2 adsorption data at 0°C ( ) V CO 2 DR . In contrast, CO2 adsorption capacities at 25°C and 15 kPa are more related to only pores of sizes lower than 0.7 nm. The capacity values obtained in column adsorption experiments were really promising. An activated carbon fiber obtained from Alcell lignin, FCL, presented a capacity value of 1.3 mmol/g (5.7%wt). Moreover, the adsorption capacity of this carbon fiber was totally recovered in a very fast desorption cycle at the same operation temperature and total pressure and, therefore, without any additional energy requirement. Thus, these results suggest that the biomass waste used in this work could be successfully valorized as efficient CO2 adsorbent, under post-combustion conditions, showing excellent regeneration performance.

“…CO 2 emissions from combustion of fossil fuels in many industries pose a serious threat to the environment. Several CO 2 capture technologies [3,4] are now available, out of which membrane technology appears promising and has the potential to capture CO 2 efficiently. A considerable progress in the application of ion transport membrane technology in the area of gas separation in industry is achieved [5].…”

The present work aims at investigating oxy-fuel combustion of liquid fuels in a concentric parallel tube oxygen transport reactor (OTR) using BSCF ion transport membrane (ITM) for oxygen separation. A computational model was developed and validated utilizing the available experimental results. It is assumed that the same model will be sufficient to capture reasonable results with liquid fuel oxy-combustion. The use of ITMs to produce oxygen for the conversion of liquid fuels into thermal energy in an oxygen transport reactor (OTR) while capturing CO 2 is presented. In this case, the OTR has two functions: O 2 separation and reaction of evaporated liquid fuel with oxygen. A parametric study of the influence of parameters such as oxygen pressure in the feed and the permeate sides on the performance of the OTR is conducted. The effect of the rates of the feed flow and sweep flow on the permeation of oxygen permeation has been evaluated. Subsequently, the effects of flow rates of feed and sweep on temperature and reaction characteristics are also explored. The optimal flow rates and flammability limits for the present geometry model to obtain maximum output are suggested. The feasibility of using liquid fuels as potential fuel to be used in near future oxygen transport reactors is presented.

Preparation and Evaluation of a Coconut Shell-Based Activated Carbon for CO2/CH4 Separation

Biomass is a widely distributed and renewable source of carbon. The main objective of this work is to produce an activated carbon from coconut shells with suitable characteristics to separate CO 2 from biogas. The textural characterization of the adsorbent has been determined. Pure component adsorption isotherms of CO 2 and CH 4 at 30, 50 and 70 • C have been measured. The results reveal that the activated carbon had high CO 2 adsorption capacity. Equilibrium of adsorption of CO 2 and CH 4 adsorption on the produced activated carbon reached 8.36 mmol/g and 4.63 mmol/g, respectively, at 30 • C and 10 bars. Moreover, the performance of the produced activated carbon, as a potential adsorbent for CO 2 capture from a CO 2 /CH 4 gas mixture, has been evaluated under dynamic conditions in a dedicated fixed-bed setup. The CO 2 and CH 4 adsorption capacities of the produced activated carbon are estimated to be 1.86 and 0.52 mol/kg, respectively, at 30 • C and 1 bar.
