Summary: Based on the COSMO-SAC model, 1-ethyl-3-methylimidazolium acetate and 1-ethyl-3-methylimidazolium p-toluenesulfonate were selected as entrainers to investigate the separation of isopropyl alcohol and isopropyl acetate azeotrope. Experimental measurements showed that the use of ILs enhanced the relative volatility of the azeotrope and eliminated the azeotropic point. The thermodynamic correlation of the systems containing ILs was explored using the NRTL model, which demonstrated its extensive applicability.

Summary: Obtaining aromatic hydrocarbons from refinery streams is a major concern in the petrochemical industry. Organic solvents and ionic liquids are commonly used for liquid-liquid extraction, but their limitations hinder industrial implementation. Cyclic carbonates have emerged as a potential solution due to their CO2 fixation capabilities and desirable properties. However, experimental data is limited and predictive models are used. This study experimentally determined the extractive properties of five cyclic carbonates and used predictive models to simulate the aromatic extraction process.

Summary: Research on ionic liquids has increased significantly in the past decade, but there is still a lack of phase equilibria data for many systems. This study measured the vapor-liquid equilibria for water in four protic ionic liquids using the hygrometric method. The NRTL model parameters were estimated using the VLE data, and the COSMO-SAC model showed semi-quantitative agreement with the experimental values, indicating its potential as an alternative in the absence of experimental information.

Summary: To reduce the emission of nitrogen oxides (NOx) produced from the combustion of nitrogen compounds (NCs) in fossil fuels, it is important to decrease the NCs content. In this study, three different anions-based protic ionic liquids (PrILs) were synthesized and used as extractants to extract pyridine. The results indicate that the hydrogen bond formed between pyridine and the three PrILs is the main driving force for the extraction of pyridine from the model mixtures.

Summary: In light of the escalating number of end-of-life tires and their environmental impact, this study proposes a disposal process that utilizes plasma gasification to convert these tires into syngas and generate hydrogen. Comparing the effects of oxygen and air versus steam and air on hydrogen production, it was found that using steam and air as the gasification agent yielded a carbon conversion rate, energy recovery rate, and exergy efficiency of 99.12%, 93.67%, and 80.04% respectively. Moreover, a suitable carbon capture process was explored, with results showing that the monoethanolamine absorption process outperformed Rectisol in terms of CO2 capture rate. However, the monoethanolamine absorption process had a lower exergy efficiency of 40.04% compared to Rectisol. The most efficient process for hydrogen production from end-of-life tires by plasma gasification involved steam and air as the gasification agent and integrated Rectisol for carbon capture, with a total exergy efficiency of 36.45%. This study provides theoretical support for end-of-life tire management and pollution reduction.

Summary: This study proposes a low-carbon ammonia synthesis process based on the cold energy utilization of liquified natural gas regasification to reduce the high energy consumption of ammonia synthesis. The process uses the cold energy released from liquified natural gas regasification as the refrigeration source for the air separation unit and carbon capture and storage unit, improving the comprehensive energy utilization efficiency. The total efficiency of the process is 42.69%, with an ammonia production capacity of 35.07 t/h. The proposed process effectively solves the high energy consumption in ammonia synthesis and provides a valuable production route for low-carbon ammonia synthesis.

To address the issues of incomplete denitrogenation and harsh conditions, an extractive denitrogenation method using eco-friendly piperazine-based ionic liquids (Pi-based ILs) was developed. The study evaluated the performance of the synthesized Pi-based ILs in removing pyrrole from oil and investigated the conformational relationship between denitrogenation performance and ILs structure. The results showed that the eco-friendly [C1Pi][Lac] exhibited the highest removal efficiency of 95.90% under optimal denitrogenation conditions.

Summary: Deep eutectic solvents (DESs) were used to separate the azeotropes of dimethyl carbonate (DMC) and isopropyl alcohol (IPA). Liquid-liquid equilibrium (LLE) data was crucial in designing the separation process, and three appropriate DESs (ChCl-Urea, ChCl-Gly, ChCl-EG) were selected. LLE data of DMC-IPA-(ChCl-Urea), DMC-IPA-(ChCl-EG), and DMC-IPA-(ChCl-Gly) were obtained through experiments, and the binary interaction parameters were determined using the NRTL model. The extraction mechanism of the DESs and the formation mechanism of the combined structures (DES-IPA/DMC) were explored through ESP and AIM analysis.

Summary: This study establishes a quantitative structure-property relationship (QSPR) model of ionic liquids (ILs) using molecular descriptors (MD), molecular identifiers (MI), and their combinations. The QSPR model, built by coupling deep neural network (DNN) and random forest (RF), shows the best performance when using MI to represent ILs and DNN. The Shapley additive explanation (SHAP) method is applied to analyze features and obtain valuable molecular structure information for prediction. Different MD and MI contribute differently in the prediction of H2S solubility and can correctly identify the impact of environmental factors (temperature and pressure). Additionally, the influence of different carbon chain lengths on the solubility of H2S is studied by calculating the electrostatic potential (ESP) between H2S and ILs.
