“…However, CFD models performed much better as indicated by all performance measures. As part of the COOLTRANS research programme (Cooper, 2012), Wareing et al (2014Wareing et al ( , 2015Wareing et al ( , 2016) investigated the near-field CO 2 dispersion using CFD models employing the Reynolds-Averaged Navier-Stokes (RANS) hydrodynamic method with adaptive mesh refinement. Comparison of the simulation results against experimental data showed broad agreement.…”

“…In addition, they developed a dedicated CFD solver, CO 2 FOAM, within the framework of OpenFOAM, specifically for the dispersion of CO 2 from pipeline releases. Simulation using CO 2 FOAM was validated against experimental measurements in Case Study 3 in the COOLTRANS programme, in which CO 2 was released through a puncture in a buried pipe (Wareing et al, 2016). Xing et al (2013) performed CFD simulations of vertical CO 2 releases from a circular source.…”

The carbon capture, utilization and storage (CCUS) technology can effectively improve global climate change. Extensive pipelines are used in CCUS to transport large amounts of pure and impure supercritical CO2(S‐CO2) from captured sites to storage, owing to pipelines being an economical and efficient means of transportation. In the event of an accidental rupture of a supercritical CO2 pipeline, causing substantial economic losses and catastrophic consequences to surroundings. Hence, it is necessary that the study of the pressure variation and temperature distribution of CO2 during pipeline blowdown contributes to understanding fracture initiation and propagation, as well as designing reliable pipelines. A laboratory‐scale setup is used to investigate the evolution of leakage behaviours and analyze heat transfer of pure and impure supercritical CO2 with different release orifices. The depressurization process, variation of inner and wall of pipeline temperature were measured. Results show that the larger is the leakage orifice, the lower is the minimum temperature of the inner pipeline. The larger is the concentrations of nitrogen (N2) in supercritical CO2 mixture, the lower is the minimum temperature of the inner pipeline, and the higher is the risk of pipeline brittle fracture. During the entire release process, the Nusselt number (Nu) was determined based on measurements to discuss the process of heat transfer between the CO2 mixture and pipeline wall. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…In addition, this methanation reaction is expected to be a component of hydrogen energy carrier systems, because the obtained methane can be used as a raw material for the generation of hydrogen gas, , which itself is a next-generation clean energy source to address global warming. Moreover, compared with carbon dioxide capture and storage technologies, , which are being investigated for mitigating CO 2 emission, the CO 2 methanation system is cost-effective and not subject to as many restrictions regarding its placement. Thus, the application of this reaction has been widely studied recently. − However, the use of conventional catalysts typically requires reaction temperatures of >400 °C, − leading to additional CO 2 emissions.…”

This study elucidates the factors reducing the CO 2 methanation reaction temperature of TiO 2 -supported Ru catalysts prepared via the polygonal barrel-sputtering method (Ru/TiO 2 (BS)) to investigate the structure-sensitivity mechanism. The smaller nanoparticles deposited in Ru/ TiO 2 (BS) (<4 nm) were amorphous RuO 2 because of air exposure after the preparation, and their surfaces were changed to island-shaped structures consisting of amorphous RuO 2 and amorphous Ru metal by H 2 exposure. In this case, dissociative hydrogen was also adsorbed in abundance on the amorphous Ru metals. Such hydrogen atoms were not observed in conventional Ru/TiO 2 catalysts. Under the supplied CO 2 + H 2 at a stoichiometric ratio of 1:4, these hydrogen atoms not only contributed to the generation of a unique CO intermediate (Ru−CO−Ru−H) from room temperature, but also reduced this CO adsorbate to methane even in low-temperature ranges (≤120 °C). These reaction steps were completely different from the reported mechanisms. Accordingly, the formation of amorphous Ru metals and the adsorption of hydrogen atoms on them are essential for reducing the CO 2 methanation temperature. These are key factors of structure-sensitivity, which would also be useful for improving activities of various catalysts.
