This review focuses on the environmental life-cycle assessment (LCA) of waste-derived catalysts, highlighting their role in process intensification and alignment with green chemistry principles. LCA is crucial for evaluating the environmental, socioeconomic, and design implications of catalyst production from waste materials. The continuous disposal of solid waste contributes to rising energy demands, environmental degradation, and human health risks, which underscores the need for efficient, green solutions. This review examines the evolution of waste-derived heterogeneous catalysts, emphasizing their significance in the circular economy and sustainable practices. The impact of analytical and physico-chemical properties on both conventional and intensified processes is explored, with reaction time and temperature identified as critical parameters in catalyst synthesis. Conventional catalyst production, often involving high temperatures (&gt;600 to &lt;900°C) and long reaction times (4–5 hours), is energy intensive. However, process intensification, reducing these conditions to &lt;100°C and &lt;100 minutes, offers a sustainable alternative by minimizing energy consumption while maintaining catalyst performance. This review also compares various analytical techniques, such as X-ray diffraction, scanning electron microscopy, and density functional theory, to assess the effectiveness of catalysts produced through intensified methods. The findings suggest that intensified synthesis processes yield results comparable to traditional methods, demonstrating their potential to reduce energy demand and promote sustainability in catalyst production from solid waste.</div></div>","PeriodicalId":9929,"journal":{"name":"Chemical Engineering and Processing - Process Intensification","volume":"211 ","pages":"Article 110208"},"PeriodicalIF":3.8,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Carbon Capture, Utilization, and Storage (CCUS) process, particularly the amine-based absorption process, is among the most developed industrial processes for capturing CO₂ from anthropogenic and natural sources. However, the energy-intensive nature of the equipment, as well as its high capital cost, inhibits widespread application. A porous hollow fiber membrane contactor (HFMC) is considered a promising technique for solvent regeneration in CO₂ capture applications. Recent research on catalyst-assisted solvent regeneration has also shown that nano catalytic materials can reduce solvent regeneration energy costs while increasing CO₂ desorption. Therefore, a self-fabricated gas-liquid membrane contactor (GLMC) module integrated with catalytically promoted CO₂ desorption to maximize their potential for solvent regeneration is used in this paper. A polytetrafluoroethylene (PTFE) hollow fiber membrane module combined with and without catalytic stripping is tested for CO₂ stripping performance under varying gas-liquid flowrates, temperatures, and initial CO₂ loading concentrations. Increasing the liquid phase temperature and liquid flowrate significantly improved CO₂ stripping, whereas increasing the gas flowrate did not increase stripping flux as much. Adding nanomaterial increased the stripping efficiency of membrane modules from 53 % to 72 % at 80 °C during CO₂ stripping experiments. Catalytically assisted systems exhibited improved stripping efficiency from 48 % to 65 % when liquid flow rates were increased from 20 mL/min to 100 mL/min. A mathematical model for the fabricated module is developed for CO₂ stripping from rich ethanolamine (MEA) solutions and it is simulated using COMSOL.

Conversely, at 40 % loading, rotation reduced EA significantly (23.57 U/mL ± 3.17 U/mL) compared to static conditions (46.91 U/mL ± 8.17 U/mL). At 60 % loading, EA was similar under both static and rotated conditions.

In this work, two schemes for the CO₂ capture process are evaluated and compared in a sustainable framework. Both schemes capture CO₂ from a combustion process to generate electricity.

Effective dispersion control ensures reliable measurements, enhanced resolution, heightened sensitivity, and improved system performance. This study emphasizes the importance of optimizing microchannel geometries, particularly curvature sections, to effectively control analyte band dispersion. To achieve this, four microchannel geometries, namely Type I to Type IV, each with distinct curvature differences, were analyzed to identify the optimal geometry with the lowest dispersion. Key parameters, including wall zeta potential, applied voltage, and the internal-to-external curvature radius ratio, were examined for their influence on dispersion. The finite element method was employed to solve the Laplace and Navier-Stokes equations for electric field and velocity distributions, while the unsteady-state diffusion-convection equation determined analyte concentration profiles. Results showed that dispersion reductions after optimization were 60 % for Type II, 48 % for Type III, and 32 % for Type IV microchannels, nevertheless for Type I microchannel dispersion remain constant after and before optimization about 70 %. Increasing the zeta potential from ζ = -0.1 V to ζ = -0.5 V led to a significant rise in dispersion from 25 % to 90 % post-optimization. Conversely, adjusting the curvature ratio R_r from 0.1 to 0.5 decreased dispersion from 42 % to 15 %.
