Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Geological conditions and enrichment patterns of helium reservoir in Yancheng Formation, Huangqiao area, Subei Basin

Shiyou shiyan dizhi
The helium (He) content in the natural gas of the Neogene Yancheng Formation in the Huangqiao area of Subei Basin ranges from 1.05% to 1.40%, which is generally higher than the industrial grade, indicating a crust and mantle composite type of helium ...

Main characteristics and effectiveness analysis of potential helium source rocks in crust-source helium-rich natural gas reservoirs

Journal of Natural Gas Geoscience
The evaluation of potential helium source rocks’ effectiveness is a core issue in the field of helium resource exploration and development. However, previous studies predominantly rely on uranium (U) and thorium (T) contents and the age of the rock for evaluating the effectiveness of potential helium source rocks, which fails to fully characterize the ...

The Chemistry of Population III Supernova Ejecta: I - Formation of Molecules in the Early Universe [PDF]

, 2009
We study the formation and destruction of molecules in the ejecta of Population III supernovae (SNe) using a chemical kinetic approach to follow the evolution of molecular abundances from day 100 to day 1000 after explosion. The chemical species included
