1Efficiency analysis of sorption-enhanced method in steam methane reforming process显示文摘The sorption-enhanced method can change the thermodynamic equilibrium by absorbing CO_(2).However,it also brings about the problems of high regeneration temperature of adsorbent and large regeneration energy consumption.In order to study the impact of enhanced adsorption methods on the overall energy cost of the system in the hydrogen production process,this paper analyzes and compares steam methane reforming and reactive adsorption-enhanced steam methane reforming with the energy consumption of hydrogen production products as the evaluation index.The results showed that the energy consumption per unit hydrogen production decreased from 276.21 MJ/kmol to 131.51 MJ/kmol,and the decomposition rate of H2O increased by more than 20%after the addition of adsorption enhancement method.It is proved that the advantage of sorption enhanced method on pre-separation of CO_(2)in the product makes up for the disadvantage of energy consumption of adsorbent regeneration.In addition,the ability of the process to obtain H element is improved by the high decomposition rate of H2O,which realizes a more rational distribution of the element.Yaowei Hu Lu Liu Kai Xu Yuncai Song Jieying Jing Huiyan Zhang Jie Feng 2023Carbon Resources Conversion2023,6,2:0
2Application of the Navier-Stokes Equations to the Analysis of the Landslide Sediments Permeability and Related Seepage Effects显示文摘The purpose of the study is to implement a new model based on the Navier-Stokes equations for the characterization of landslide sediments interacting with a moving fluid.The model is implemented by combining Hypermesh,the LS-DYNA software and MATLAB.The results show that the main factors affecting the permeability of landslide sediments are the genetic mechanism,the structure and composition of materials,material lithology,and stress.The characteristics and mechanism of permeability changes are determined by adjusting the water levels of fluids.It is found that the permeability of landslide sediments increases at the front and decreases in the middle and at the rear of the considered domain.The magnitude of the internal flow for the whole system decreases first and then increases with a change in the water level during seepage.Meng Song Yuncai Liu Zhen Wang 2022Fluid Dynamics & Materials Processing2022,18,2:0
