Herein, γ-AlOOH/reduced graphene oxide (rGO) 3D nanocomposites with different morphology structures were obtained following a one-step microwave-assisted hydrothermal strategy. Ciprofloxacin (CIP) adsorption experiments were performed to investigate the relationship between adsorption performance and structural properties of the products. The adsorption performance of the γ-AlOOH/rGO nanocomposites were influenced by morphology, specific surface area and pore volume. Cl-AlOOH/rGO and N-AlOOH/rGO which possessed the similar morphological structure followed Elovich model well, but the kinetics adsorption behavior of S-AlOOH/rGO could well be elaborated by the pseudo-second order model. Cl-AlOOH/rGO with the highest specific surface area (203.48 m²/g) and pore volume (0.216 m³/g) exhibited the highest the maximum adsorption capacity of 930.0076 mg/g. A multiple adsorption mechanism concerned with hydrogen bonds, π-π interaction, pore filling, complexation and van der Waals force was proposed. Benefiting from their 3D structures, all the products showed excellent reusability. This work not only gives valuable insights into the impact of structural attributes, but also provides a new thought for engineering and preparing new-type of adsorbent.</div></div>","PeriodicalId":10019,"journal":{"name":"Chemical Engineering Research & Design","volume":"217 ","pages":"Pages 24-37"},"PeriodicalIF":3.7,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734896","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}

This study introduces a novel gas channel blocking strategy using the phase transition properties of fatty acid based CO₂-responsive ionic liquids (ILs). The ILs were synthesized from choline hydroxide (Ch) and high-melting-point fatty acids (FA), including myristic acid (C14) and palmitic acid (C16), named FA-Ch ILs. These ILs demonstrate phase transformation behavior after CO₂ injection, leading to the precipitation of FA as solid particles. The FA-Ch ILs aqueous solution exhibits low viscosity, ensuring excellent injectivity for oilfield applications. After CO₂ injection, the precipitated FA particles act as gas channeling plugging agents, while the protonated Ch ions effectively inhibit clay swelling to enhance oil recovery with a synergistic effect. Structural properties and interaction mechanisms of the FA-Ch system were characterized by FT-IR, ¹H NMR, and molecular dynamics simulations. The particle size of the FA precipitates was regulated by adjusting FA-Ch concentration and CO₂ injection rate to make it suitable as a profile control agent. Furthermore, Ch⁺ ions demonstrate clay swelling inhibition comparable to traditional inhibitors like KCl.

While several catalytic strategies for its production exist, a common challenge is the lack of an integrated process that combines both production and purification. Currently, these steps are performed separately, with distillation being energy-intensive, especially at low yields. This study presents a novel approach by integrating both production and purification of GVL in a single, energy-efficient operation using reactive distillation.The novelty of this work lies in the design and optimization of a reactive distillation column, where key operating conditions and design parameters are carefully selected to ensure that both chemical reactions and component purification occur efficiently within the same unit. Experimental data from the literature were used to model the process kinetics, ensuring the simulation accurately reflects experimental conditions. This integrated approach not only reduces energy consumption but also improves the overall efficiency of GVL production, offering a more sustainable and cost-effective alternative for industrial applications. By employing a multiobjective optimization framework, the design balances economic, environmental, and operational objectives, achieving a reduction in total annual cost (TAC) to 43 % and environmental impact (Eco Indicator 99, EI99) to 45 % of the values associated with conventional processes.

This research systematically explores the characteristics of the droplets of the internally mixed pneumatic atomization nozzle and its interaction with the dust through theoretical analysis and experiment. Laser particle size analyzer and particle image velocimeter were used to measure the particle size and velocity field distribution of fog droplets. A gas dust liquid three-phase coupling experimental platform was constructed to capture fog films with specific properties of fog droplet groups for dust fog coupling experiments. The response surface methodology was used to analyze the dust fog coupling effect under different operating conditions. The experimental results show that there is a significant temporal and spatial difference between the droplet velocity and the airflow velocity. The velocity of the aerosol flow field is negatively correlated with the spray distance, and positively correlated with the aerodynamic pressure. The attenuation of the airflow velocity is far greater than that of the droplet. Droplet size is negatively correlated with aerodynamic pressure, and positively correlated with water flow and spray distance. In the coupling effect of dust and mist, dust particles with particle sizes of 0–2.5 μm and 5–10 μm are dominated by droplet velocity, while dust particles with particle sizes of 2.5–5 μm are significantly affected by their own velocity. When the droplet velocity reaches 18–23 m/s, the fog film has a good effect on capturing respiratory dust at different velocities, and the dust reduction efficiency reaches a peak of 86.13 %. The momentum ratio and kinetic energy ratio of fog droplets to dust have a significant nonlinear effect on the removal of 5–50 μm dust from airborne airflow, with the removal efficiency of 10–50 μm dust showing a unimodal distribution as the momentum ratio and kinetic energy ratio increase.

An operability mapping approach is first utilized to systematically screen the feasible steady-state design space at low-, medium-, or high-risk levels through comprehensive analyses of process design, uncertainties, and constraint violations. To further understand the open-loop dynamic behaviors, a Monte Carlo strategy is developed which can provide a probability of various system responses under uncertainty by simulating randomly sampled input and disturbance parameters. The open-loop analysis determines the safe operating bounds which are leveraged as path constraints for advanced control. Multi-parametric model predictive control is then applied to design the optimal risk-aware control strategy.
