Co2 Adsorption On Solid Sorbents
… and operational parameters for different sorbents were revieand summarized. Efficient industrial applications for CO2 capture require that solid sorbents possess an adsorption capacity between 1000-2000µmol/g or more together with a long-term regeneration capacity. Economical consideration …

BISMUTH-FUNCTIONALIZED SORBENTS FOR RADIOIODINE CAPTURE
… and no Bi2O3 was detected. The iodine captured sorbents were leached with water to simulate a flooded situation. A steady increase in iodine concentration was observed until all nanoparticles were converted to bismuth oxy iodide, a water insoluble compound. Carbon foam loaded with bismuth …

Industrial Wastewater Treatment Using Dolomite And Dolomitic Sorbents
1.1 - The incentive behind this study<br/>It was said of Lough Ree in Ireland that; “The Lake of kings becomes the sump of Ireland” the Irish Times suggested that this severe eutrophic problem was due to “ 50-60 tonnes of phosphates and 10 tonnes of nitrates finding their way into the lake …

Metal organic frameworks as sorbents for volatile organic compounds
… These features make MOFs desirable as sorbents for applications such as gas storage, gas separation, and gas sensing. In this work, MOF thin films of UiO-66-R, where R = -H, -NH2, and-NO2, were fabricated onto Au-coated Si wafers and Au-coated quartz crystal microbalance surfaces using …

Models of high-temperature desulfurization using zinc-based sorbents
This study focuses on determining models that are currently available to describe gas-solid reactions to predict the observed (experimental) results from a series of TGA experiments. Variations of the GPM (Grainy Pellet Model) were used and shown to give good agreement with experimental conversion …

Collection of gas phase chlorine using bonded silica sorbents
… for collection of gas phase chlorine. Sorbents were prepared by bonding aminopropyl groups to a substrate (silica gel or filters) and then reacting with alkyl or aryl substituted sulfonyl chloride to produce the corresponding surface bound sulfonamide. Silica gel surfaces were …

Hollow fiber sorbents for the desulfurization of pipeline natural gas
… polymer barrier layer on the outside of fiber sorbents allows only thermal interactions with the regeneration media, thereby promoting consistent sorption capacity over repeated cycles. A simplified flow pattern minimizes pressure drop, porous core morphology maximizes sorption efficiencies, …

Calcium oxide-based sorbents for CO2 capture at high temperature
… utilized to prepare highly stable CaOcontaining sorbents for CO2 capture. The mechanochemical approach is as an example of top-down synthesis of materials, while spray pyrolysis is considered a bottom-up approach. First, a systematic study on the use of mechanochemistry (e.g., mechanical milling) …

Lumped approach for sorption of organic contaminant mixtures to simulated aquifer sorbents
… benzene), in mixtures to simulated aquifer sorbents with fractions of organic carbon (foc) ranging from 0.005 to 0.221 % were evaluated. The lumped approach consists of grouping one or more components in mixtures of NOCs into a fewer number of pseudocompounds that exhibit similar behavior …

Evaluation of economical sorbents for the removal of metolachlor from contaminated wastewater
… did not affect the sorption capacity of the sorbents at the concentration levels tested. However, isotherm plots showed S-shaped curve behavior for all of the sorbents in the presence of unformulated metolachlor, while a C-shaped curve was seen when the sorbents were mixed with formulated …

Evaluation of reactive cap sorbents for in-situ remediation of contaminated sediments
… phenanthrene and pyrene on two types of sorbents being evaluated for use in a mat: activated carbon and organoclays. Several kinetic and isotherm studies have been conducted using several formulations of activated carbons and organoclays as sorbents to treat individual PCB congeners and …

Plastic Waste-Derived CO2 Sorbents and Methods for Enhanced Selectivity and Stability
… reduction targets; however, many of these sorbents suffer drawbacks related to their cost, performance, or both. Due to these shortcomings, carbon capture solid sorbents have only just now begun to achieve industrial relevance. Chapter 1 will discuss the carbon capture problem and general …

Development of Amino Acid-based Solid Sorbents for Post-Combustion CO2 Capture
… novel and efficient amino acid (AA)-based solid sorbents for post-combustion CO2 capture. Amino acid anion-functionalized ionic liquids (AAILs) have been synthesized and mainly employed as promising AA-based materials for CO2 capture study, due to their good reactivity with CO2. Three major …

Metal oxide sorbents for carbon dioxide capture prepared by ultrasonic spray pyrolysis
… shown that the morphology of USP-synthesized CaO sorbents can be easily controlled but that there is little difference between each sorbent in cyclic carbonation/calcination stability. Sorbents synthesized via USP, however, perform better than commercially available CaCO3. Finally, the effects of …
