With increasing interest in deep and ultra-deep oil and gas reservoirs, understanding how miscibility varies with burial depth has become essential. Pressure and temperature, both varying with depth, are key parameters affecting miscibility. Although their individual effects have been extensively studied, the overall influence of burial depth on oil-gas miscibility remains insufficiently explored. In this work, molecular dynamics simulations were conducted to investigate the miscible behavior between multi-component crude oil and CO<sub>2</sub> at different burial depths in Hami, Xinjiang, China. A quantitative method was developed to assess the miscibility of component and overall crude oil. Simulation results reveal a non-monotonic relationship between depth and miscibility, which varies from about 54.8–72.4 %, peaking near 2500 m. The underlying mechanisms were further analyzed in terms of interaction energy and diffusion coefficient. As burial depth increases, oil-gas net interactions weaken, hindering miscibility, with the interaction energy of saturates and aromatics decreasing by 17.7 % and 12.6 %, respectively. In contrast, molecular diffusion is enhanced, with diffusion coefficients of hydrocarbon components increasing by 1.6–5 times, promoting miscibility. The competition between these effects produces an optimal miscibility depth near 2500 m. Therefore, CO<sub>2</sub> flooding can be directly implemented in the preferred area, while injection pressure can be increased in non-preferred zones to enhance miscibility. This work provides a molecular-level understanding of how burial depth influences CO<sub>2</sub>-oil miscibility and offers theoretical insights for optimizing CO<sub>2</sub> flooding strategies.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"728 ","pages":"Article 138522"},"PeriodicalIF":5.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145218644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We employed different synthetic methods (solid-state grinding and impregnation) and temperatures (400 and 600 °C) to clarify the key parameters governing the adsorption of MB. Characterization results indicated that solid-state grinding was more favorable for the dispersion of MgO nanoparticles within the support pores, whereas impregnation led to MgO agglomeration on the surface. The adsorbents prepared via the impregnation method faster achieved adsorption equilibrium at both low and high MB concentrations because of easily accessible MgO sites on the surface. However, adsorption isotherms showed superior MB adsorption capacity of the adsorbents prepared via solid-state grinding, which was attributed to the highly dispersed MgO within the mesopores. The adsorbents prepared at 600 °C exhibited higher MB adsorption capacity than those prepared at 400 °C. Particularly, the maximum adsorption capacity of SBA-15@Mg-600 for MB was 827.54 mg/g. The MB adsorption capacity increased with pH because of the strengthening of electrostatic attraction. The presence of ions in water, especially Ca<sup>2 +</sup> , inhibited MB adsorption via competitive adsorption. The adsorption mechanism primarily involved the formation of hydrogen bonds, electrostatic interaction, and pore filling. After five regeneration cycles, SBA-15@Mg-600 maintained stable adsorption performance, whereas the adsorption capacity of MCM-41-based adsorbents notably decreased. These results indicate that SBA-15@Mg-600 can serve as a highly effective and stable adsorbent for MB removal.

This distribution is expected to be determined by the reduction and nucleation rates of the specific metal pair. Metal pairs such as Au-Rh, exhibit contrary trends, whereby the faster reducing metal (Au) nucleates slower, and the slower-reducing metal nucleates faster (Rh). A kinetic computer simulation study was carried out to investigate the structural arrangement of Au-Rh nanoparticles synthesized in microemulsions. Results indicate that Au, due to its rapid reduction, nucleates earlier and tends to accumulate in the core, while Rh is deposited in the outer layers. The findings provide mechanistic insights into the nucleation process within micelles. A systematic variation of the conucleation rate of Au/Rh pair is carried out. The results show that the slower the conucleation rate, the later the Au deposition, resulting in greater mixing of the two metals in the final structure. In addition, a detailed study is made of the impact of microemulsion dynamics on nanoparticle architecture. A slow intermicellar exchange rate delays the reduction of Au and the exchange of Au atoms between micelles. Consequently, nucleation is hindered because it takes longer for enough free Au atoms to be found within the same micelle to initiate nucleation. The influence of the intermicellar exchange rate is particularly significant when conucleation is slow.
