“…No information is available on surface protonation/deprotonation of kerogen. The point of zero charge of other alike natural carbon materials such as algae and coal charcoals were found to be close to neutral pH 33 . Therefore, the assumption of no surface protonation/deprotonation may be a reasobale approximation of an actual system.…”

Carbon dioxide-enhanced metal release from kerogen

Heavy metals released from kerogen to produced water during oil/gas extraction have caused major enviromental concerns. To curtail water usage and production in an operation and to use the same process for carbon sequestration, supercritical CO2 (scCO2) has been suggested as a fracking fluid or an oil/gas recovery agent. It has been shown previously that injection of scCO2 into a reservoir may cause several chemical and physical changes to the reservoir properties including pore surface wettability, gas sorption capacity, and transport properties. Using molecular dynamics simulations, we here demonstrate that injection of scCO2 might lead to desorption of physically adsorbed metals from kerogen structures. This process on one hand may impact the quality of produced water. On the other hand, it may enhance metal recovery if this process is used for in-situ extraction of critical metals from shale or other organic carbon-rich formations such as coal.

“…The bands on1584 e 875 cm -1 , which can be assigned respectively to the (C=C) e (CH) aromatic, are respectively shifted to 1594 and 783 cm -1 in the spectrum of the biochar with the dye. In addition, there is an increase in the relative intensity of the bands in 1384 and 1328, assigned respectively to the (C-C) in aromatics and (C-O) in phenols and decreased relative intensity of the band in 1099 cm -1 that can be attributed to the (C-O-C) (Chia et al, 2012;Mupa et al, 2016;Zhu et al, 2018;Fazal et al, 2019) . Thus, from the results obtained by infrared spectroscopy, it can be inferred that the adsorption that occurs is not chemical, as for this to occur, more significant spectral changes would be necessary as described in the literature (Liu et al, 2020;Suwunwong et al, 2020).…”

Dyes represent a class of contaminants with a high impact on aquatic ecosystems due to their toxicity. As these pollutants are difficult to degrade, studies on the treatment methods for these compounds are highly important to minimize damage to water bodies that receive these effluents. In this work, the adsorption and slow filtration processes using charcoal produced from the pyrolysis of Andropogon grass (Andropogon gayanus cv. Planaltina) were individually evaluated for removal of the methylene blue dye. The adsorption studies included the evaluation of kinetic behavior, evaluating pseudo-first-order and pseudo-second-order models and adsorption isotherms using the Langmuir, Freundlich, and Dubinin-Radushkevich models. According to the results, it was found that the adsorptive process had greater efficiency between pH 8 and 10. The pseudo-second-order model better described the adsorption kinetic behavior (R2 = 0.9722) and as for the adsorption isotherms, Freundlich's model best described the process. The maximum charcoal adsorption capacity of Andropogon grass for the removal of methylene blue was 17.63 mgg-1. In the filtration process, dye removal reached an efficiency above 99% at filtration rates of 1.5 and 2.1 m3m-2day-1.
