High-temperature chemical reactions are ubiquitous in (electro) chemical applications designed to meet the growing demands of environmental and energy protection. However, the fundamental understanding and optimization of such reactions are great challenges because they are hampered by the spontaneous, dynamic, and high-temperature conditions. Here, we investigated the roles of metal catalysts (Pd, Ni, Cu, and Ag) in the high-temperature reverse water-gas shift (RWGS) reaction using in-situ surface analyses and density functional theory (DFT) calculations. Catalysts were prepared by the deposition-precipitation method with urea hydrolysis and freeze-drying. Most metals show a maximum catalytic activity during the RWGS reaction (reaching the thermodynamic conversion limit) with formate groups as an intermediate adsorbed species, while Ag metal has limited activity with the carbonate species on its surface. According to DFT calculations, such carbonate groups result from the suppressed dissociation and adsorption of hydrogen on the Ag surface, which is in good agreement with the experimental RWGS results.

“…With the aggravation of global warming, the emission and management of greenhouse gases have drawn more attention in recent years. − It is necessary to find good approaches to dispose of CO 2 effectively and turn the greenhouse gas into a treasure in the production. Supercritical carbon dioxide (SC-CO 2 ) fracturing may give a good solution in the oil and gas production industry, which combines the utilization of greenhouse gas and the development of energy resources. − As is known to all, with the consumption of conventional resources, the emphasis and difficulty in the oil and gas industry are the unconventional reservoirs. − However, the unconventional reservoirs need to use the fracturing technology during development on account of its low porosity, low permeability, low pore-throat radius, and high gas-flow resistances. − Hydraulic fracturing has been widely used and has achieved good performance in the exploitation of oil and gas resources nowadays, while the huge water consumption and formation pollution bring a lot of limitations to the technology .…”

Supercritical carbon dioxide (SC-CO 2 ) fracturing is a promising stimulation treatment in the unconventional oil and gas industry, which combines the utilization of greenhouse gas and the development of energy resources. Aiming to study the proppant transport in fractures, which is one of the most important issues in this technology, a generalized and pragmatic numerical method coupled with multiphase flows, physical property models of CO 2 , and heat and mass transfer in the formation rock has been established to calculate the proppant transport in fractures of SC-CO 2 fracturing. Experimentally, experimental validation of the proppant transport was conducted, which verifies the accuracy of the simulation results. Combining experimental and simulation results, the flow condition of proppant−CO 2 two-phase flow was divided into a stationary layer, a rolling layer, a saltatory layer, a suspending layer, and a pure liquid/gas layer. Numerically, movement laws of proppant beds in fracture and influence factors on the distribution of proppant beds were analyzed. Proppant bed was formed near the inlet of the fracture at the initial stage of fracturing, and the height and length of the bed would increase concurrently until reaching a steady state. The equilibrium height has positive correlations with the injection temperature, proppants' volume fraction, density, and diameter and negative correlations with the injection pressure and displacement. Nevertheless, the equilibrium time has negative correlations with all these factors except pressure. Additionally, the proppant transports of SC-CO 2 and water were compared, which indicated that water has better proppant-carrying capacity with lower proppant bed height and longer proppant bed length at the same fracturing time. The distribution of the proppant bed with the structure of a nozzle inlet is relatively homogeneous in the near-wellbore zone of the fracture compared to the cuboid structure, which could reduce the risk of fracture closure in the near-wellbore zone. Results obtained in this paper could provide references for SC-CO 2 fracturing design which would promote the development of this technology.

“…Traditional CGS projects may cause a series of problems due to the continuous large-scale injection of CO 2 and the reservoir pressure build-up, such as caprock fracturing, upward CO 2 leakage, fault activation, and induced seismicity, all of which will limit the injection capacity of CO 2 and threaten the safety and security of CGS projects [6][7][8]. The alternative geoengineering approach of CCUS (Carbon Capture, Utilization, and Storage) technology [9][10][11][12] is an attractive and potentially viable way to significantly reduce anthropogenic carbon emissions with the benefit of economically productive activities [13].…”

CO 2 geological storage (CGS) proved to be an effective way to mitigate greenhouse gas emissions, and CO 2 -enhanced water recovery (CO 2 -EWR) technology may improve the efficiency of CO 2 injection and saline water production with potential economic value as a means of storing CO 2 and supplying cooling water to power plants. Moreover, the continuous injection of CO 2 may cause a sharp increase for pressure in the reservoir system, so it is important to determine reasonable reservoir pressure control strategies to ensure the safety of the CGS project. Based upon the typical formation parameters of the China Geological Survey CO 2 -EWR test site in the eastern Junggar Basin, a series of three-dimensional (3D) injection-extraction models with fully coupled wellbores and reservoirs were established to evaluate the effect of the number of production wells and the well spacing on the enhanced efficiency of CO 2 storage and saline production. The optimal key parameters that control reservoir pressure evolution over time are determined. The numerical results show that a smaller spacing between injection and production wells and a larger number of production wells can enhance not only the CO 2 injection capacity but also the saline water production capacity. The effect of the number of production wells on the injection capacity and production capacity is more significant than that of well spacing, and the simulation scenario with 2 production wells, one injection well, and a well spacing of 2 km is more reasonable in the demonstration project of Junggar Basin. CO 2 -EWR technology can effectively control the evolution of the reservoir pressure and offset the sharp increase in reservoir pressure caused by CO 2 injection and the sharp decrease of reservoir pressure caused by saline production. The main controlling factors of pressure evolution at a certain spatial point in a reservoir change with time. The monitoring pressure drops at the beginning and is controlled by the extraction of water. Subsequently, the injection of CO 2 plays a dominant role in the increase of reservoir pressure. Overall, the results of analysis provide a guide and reference for the CO 2 -EWR site selection, as well as the practical placement of wells.
