The clathrate hydrate memory effect is a fascinating phenomenon with potential applications in carbon capture,utilization and storage(CCUS),gas separation,and gas storage as it can accelerate the secondary formation of clathrate ***,the underlying mechanism of this effect remains *** gain a better understanding of the mechanism,we conducted molecular dynamic simulations to simulate the initial formation and reformation processes of methane *** this work,we showed the evolution process of hydrate residual structures into hydrate *** simulation results indicate that the residual structures are closely related to the existence of hydrate memory effect,and the higher the contribution of hydrate dissociated water to the hydrate nucleation process,the faster the hydrate *** hydrate dissociation,the locally ordered structures still exist after hydrate dissociation and can promote the formation of cluster structures,thus accelerating hydrate ***,the nucleation process of hydrate and the formation process of clusters are *** size of clusters composed of cup-cage structures is critical for hydrate *** residence time at high temperature after hydrate decomposition will affect the strength of the hydrate memory *** simulation results provide microscopic insights into the occurrence of the hydrate memory effect and shed light on the hydrate reformation process at the molecular scale.

Geo-Spatial Mapping of the Northern Bushveld Rustenburg Layered Suite (RLS) in South Africa

引用

Open Journal of Geology 2016年第5期6卷 302-313页

作者： O. A. Bamisaiye P. G. Eriksson J. L. Van Rooy H. M. Brynard S. Foya Department of Geology University of Pretoria Pretoria South Africa Council for Geoscences Pretoria South Africa

The focus of this paper is on determination of the geometry and stratigraphic contact pattern of the Rustenburg Layered Suite (RLS) in the Northern Bushveld Complex area using available borehole data and trend surface analysis technique. This technique was used to analyse over one hundred borehole log data in the Northern Bushveld Complex in order to describe the geometric pattern and trends of the RLS rocks. The results demonstrate the usefulness of this technique in identifying structural features. Regional trends of each of the stratigraphic units reveal the presence of regional structures that were not obvious at the surface. This first part of the paper focused on the Northern Bushveld Complex, while the second and the third part focused on the eastern and western Bushveld limbs respectively.
