Traditional steam injection methods have been effective, but they are criticized for excessive water usage and significant carbon dioxide emissions. In response, this study investigates the use of terpenes─specifically limonene, citronella, turpentine, and beta-pinene─as sustainable and environmentally friendly solvents, comparing their performance with that of toluene, a commonly used but toxic solvent. This research involved 11 core flooding experiments using three different heavy oil samples (O1, O2, and O3) to assess the solvency and recovery efficiency of terpenes. Each experiment aimed to evaluate how terpenes influence oil recovery under varying conditions of steam and carbon dioxide injection and varying oil viscosities. Produced oil and water samples were collected at 20 min intervals and analyzed for emulsion stability and oil quality using TGA/DSC, while displacement efficiency was assessed through spent rock analysis. Results demonstrated that limonene, beta-pinene, and turpentine achieved oil recovery efficiencies comparable to toluene, approximately 75%, confirming their effectiveness as organic solvents. All terpenes acted as demulsifiers, enhancing the quality of the oil during production. Additionally, the study found that while steam-solvent injection negatively impacted oil recovery, carbon dioxide proved to be an effective secondary agent for enhancing oil production in lower-viscosity oils without compromising oil quality. The study concludes that terpenes hold promise as safe, effective, and sustainable solvents for heavy oil recovery. Their nontoxic nature, ease of handling, and effective performance position them as viable alternatives to conventional, harmful solvents like toluene. Furthermore, the use of carbon dioxide as a secondary injection medium offers a method to improve efficiency and reduce environmental impact, reinforcing the potential of terpene-based solvents in environmentally conscious heavy oil recovery practices.

Conventional methane isotherm adsorption experiments often suffer from human error and experimental artifacts, leading to inaccurate and poorly reproducible outcomes. Furthermore, they are time-consuming to conduct, requiring specific and well calibrated experimental equipment. In this paper, a Random Forest (RF) algorithm is introduced to improve the accuracy and reliability of methane adsorption capacity prediction. Approximately 200 sets of experimental data, including parameters such as experimental temperature, equilibrium pressure, moisture, ash content, and volatile matter of coal samples, were collected and analyzed to establish a prediction model based on the RF algorithm. The robustness and reliability of the model were validated using K-Fold cross-validation and hyperparameter optimization. The results indicate that the Random Forest algorithm performs exceptionally well in predicting methane adsorption capacity, with optimal values for mean squared error (MSE) and the coefficient of determination (<i>R</i><sup>2</sup>), demonstrating a high correlation between predicted and actual values. Machine learning algorithms are innovatively combined with traditional experimental methods in this study. By training the model using large data sets, issues of error and reproducibility in traditional experiments are addressed, improving experimental efficiency and providing a more reliable method for evaluating coalbed methane resources.

In this article, the research progress of hydrogen production from methane pyrolysis by molten media in recent years (from 2017 to the present) is summarized, including liquid-phase catalysts and solid–liquid two-phase catalysts. In the liquid-phase catalyst section, the application of molten metals, molten salts, and molten metal–molten salt composites in methane pyrolysis is analyzed in detail, and their catalytic properties and reaction mechanisms are assessed. Molten metals have good methane pyrolysis activity, which is still limited by carbon pollution loss, and molten salts have good carbon cleaning ability but lack catalytic ability. Molten metal–molten salt composites combine efficient methane pyrolysis and high-purity carbon preparation but with high activation energy barriers. Then, the research progress of solid–liquid two-phase catalysts combining the interplay between molten media and solid catalysts is discussed. The combination of two-phase catalysts makes up for the limitation of liquid-phase catalysts, which can effectively reduce the activation energy barrier, but there are difficulties in industrialization. In addition, the economic feasibility of methane pyrolysis in molten media for hydrogen production is evaluated. The carbon materials market is the key to determining the economic benefits of the process. Finally, the challenges and prospects of the current research are summarized.
