Title: Robust Immobilized Amine CO₂ Sorbent Pellets Utilizing a Poly(Chloroprene) Polymer Binder and Fly Ash Additive

Abstract

Pelletization of ca. 50 wt % amine/silica carbon dioxide sorbents was achieved with the novel combination of fly ash (FA) as a strength additive and hydrophobic poly(chloroprene) (PC) as a binder. The PC content and overall synthesis procedure of these materials were optimized to produce pellets, labeled as FA/E100-S_(20/80)_12.2, with the highest ball-mill attrition resistance (<0.5 wt % by fines, 24 h) and maximum CO₂ capture capacity of 1.78 mmol CO₂ g^-1. The strength of the pellets was attributed to hydrogen-bonding of the relatively homogeneous PC network with the interlocked FA and BIAS particles (DRIFTS, SEM-EDS). The low degradation of 3–4 % in the pellet's CO₂ capture capacity under both dry TGA (7.5 h) and practical fixed-bed (6.5 h dry; 4.5 h humid,≈5 vol % H₂O) CO₂ adsorption–desorption conditions highlights the pellet's excellent cyclic stability. These robust pellet characteristics make PC/FA/sorbent materials promising for commercial scale, point-source CO₂ capture.

Steam-Stable Basic Immobilized Amine Sorbent Pellets for CO₂ Capture Under Practical Conditions

Journal Article Wilfong, Walter Christopher ; Kail, Brian W. ; Howard, Bret H. ; ... - ACS Applied Materials and Interfaces

Pelletization of basic immobilized amine sorbent (BIAS) particles is required to improve their mechanical strength and facilitate their practical CO₂ capture application under fixed or dynamic reactor conditions. Herein, we utilized two methods to prepare amine-functionalized BIAS pellets. Method (ii-a) involved combining latex polychloroprene (PC)/polyamine solutions with fly ash (FA)/BIAS powder to form sorbent pellets. Alternatively, method (ii-b) entailed shaping and drying wet pastes of binder solution plus FA/SiO₂ powder into pellet supports. These supports were then functionalized with leach-resistant polyethylenimine MW = 800 (PEI₈₀₀)/N-N-diglycidyl-4-glycidyloxyaniline (tri-epoxide cross-linker, E3) or ethylenamine E100/E3 mixtures. All pellets were screened for CO₂ capture bymore »« less

Pelletization of Immobilized Amine Carbon Dioxide Sorbents with Fly Ash and Poly(vinyl chloride)

Journal Article Wilfong, Walter Christopher ; Gray, McMahan L. ; Kail, Brian W. ; ... - Energy Technology

Abstract A combination of coal fly ash (FA) and a polymer binder, namely, poly(vinyl chloride) (PVC), was used to pelletize immobilized amine CO ₂ sorbents. The pelletization of mixtures of FA and 50 wt % tetraethylenepentamine (TEPA) or ethylenimine oligomer mixture ( M _w =423)/silica (EI ₄₂₃ ‐S) with PVC created a rigid PVC/FA/sorbent network. The strength of the network was attributed, in part, to the hydrogen bonding of PVC with the hydroxy and amine groups of the FA and sorbent (infrared spectroscopy). Increasing the PVC molecular weight or FA content enhanced the pellet strength and reduced CO ₂ capture. The optimummore »« less

Screening of binders for pelletization of CaO-based sorbents for CO{sub 2} capture

Journal Article Manovic, Vasilije ; Anthony, Edward J - Energy and Fuels

CaO-based CO{sub 2} looping cycle technology is a promising method for separation of CO{sub 2} from flue gas and syngas at high temperatures. The process of CO{sub 2} capture is expected to take place in fluidized-bed combustion (FBC) systems, which implies significant attrition and elutriation of the solid sorbent. Hence, both reactivation of spent sorbent and preparation of modified CaO-based sorbent may be required to maximize the performance of the sorbent. We present initial results on the screening of suitable binders for pelletization. Two types of bentonite (Na- and Ca-bentonite) and four types of commercial calcium aluminate cements (CA-14, CA-25,more »« less

Bench Scale Development and Testing of Aerogel Sorbents for CO₂ Capture Final Technical Report

Technical Report Begag, Redouane

The primary objective of this project was scaling up and evaluating a novel Amine Functionalized Aerogel (AFA) sorbent in a bench scale fluidized bed reactor. The project team (Aspen Aerogels, University of Akron, ADA-ES, and Longtail Consulting) has carried out numerous tests and optimization studies to demonstrate the CO₂ capture performance of the AFA sorbent in all its forms: powder, pellet, and bead. The CO₂ capture target performance of the AFA sorbent (all forms) were set at > 12 wt.% and > 6 wt.% for total and working CO₂ capacity, respectively (@ 40 °C adsorption / 100 – 120 °Cmore »« less

Sub-Ambient Temperature Direct Air Capture of CO ₂ using Amine-Impregnated MIL-101(Cr) Enables Ambient Temperature CO ₂ Recovery

Journal Article Rim, Guanhe ; Kong, Fanhe ; Song, Mingyu ; ... - JACS Au

Due to the dramatically increased atmospheric CO₂ concentration and consequential climate change, significant effort has been made to develop sorbents to directly capture CO₂ from ambient air (direct air capture, DAC) to achieve negative CO₂ emissions in the immediate future. However, most developed sorbents have been studied under a limited array of temperature (>20 °C) and humidity conditions. In particular, the dearth of experimental data on DAC at sub-ambient conditions (e.g., –30 to 20 °C) and under humid conditions will severely hinder the largescale implementation of DAC because the world has annual average temperatures ranging from –30 to 30 °Cmore »« less
