Carbon capture from steam methane reforming (SMR) stream by supported ionic liquids (SILPs) using commercial supports

The selective capture of CO2 from reforming stream for H2 productions was evaluated in fixed-bed columns using Supported Ionic Liquid Phases (SILP) based on commercial ionic liquid 1-butyl-3-methylimidazolium acetate ([Bmim][Acetate]). Thirteen different commercial supports were evaluated, varying i...

Thirteen different commercial supports were evaluated, varying in particle size, porosity and surface chemistry. Selected supports were used to prepare SILP materials via incipient wetness impregnation, incorporating ~40 wt% IL. Supports and SILP sorbent characterization were performed using scanning electron microscopy, nitrogen adsorption-desorption isotherms and thermogravimetric and elemental analysis. A synthetic gas mixture modeling a Steam Methane Reforming (SMR) stream with composition of H2/CO2/CH4 (70/ 25/5 %) was used to evaluate the CO2 capture performance of the six different SILP materials by means of fixed- bed experiments. Measured breakthrough curves at 30 ºC under various operating pressures (1, 5, and 10 bar) allowed to estimate thermodynamic and kinetic parameters on CO2 sorption from SMR gas model. The experimental fixed-bed tests revealed CO2 sorption capacities of 0.4–0.6 mol⋅kg⁻¹ , with pre-breakthrough times up to 20 min and CO2 removal efficiencies above 90 % at 10 bar. Thermodynamics (sorption capacity) was maintained independently of the support, while particle size governed sorption/desorption kinetics, with smaller particles exhibiting faster mass transfer and more efficient use of the sorbent. Increasing CO2 partial pressure enhanced both sorption capacity and kinetic constants, leading to improved process performance. The LDF model successfully described the experimental breakthrough curves, using KMTC as reference kinetic parameter. Additionally, regeneration tests, using a N2 stripping stream and pressure-swing, were conducted on one selected SILP material over seven sorption-desorption cycles. So, experimental results highlighted the improved performance of SILP materials with smaller particle sizes, with high effective CO2 sorption capacity and enhanced sorption and desorption rates, enabling treating SMR streams by a simple two-fixed bed configurationThe authors are grateful to Ministerio de Ciencia e Innovación of Spain (project PID2023–150532OB-I00), CDTI (SHINEFLEET Project MIG-20201034) and Comunidad de Madrid (project TEC2024/BIO-17) for financial supportElsevierDepartamento de Ingeniería QuímicaFacultad de Ciencias20252025-10-22research articlehttp://purl.org/coar/resource_type/c_2df8fbb1VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/10486/745300https://dx.doi.org/10.1016/j.jece.2025.119869reponame:Biblos-e Archivo.
