Diffusive flux rates expressed in mass units are generally higher for N_2 than for CH_4. Both methane and (to a lesser extent) nitrogen diffusion coefficients decrease with increasing total organic carbon (TOC) content of the rock samples because of sorption processes on the organic matter. ...
16). This optimized molecular nanojunction (MTPA-CA:CNP147, 4:6 wt/wt, 9 wt% Pt) produced 2,576 μmol hydrogen over 5 h photolysis using 1.56 mg catalyst, corresponding to an exceptional mass-normalized HER of 330.3 mmol h−1 g−1 (full spectrum, average light ...
1) The strong ionic forces of the divalent calcium ion makes it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while minimising COS formation. Light mercaptans are also adsorbed.2) It is also used for the separation of normal- and ...
We engineered a machine learning approach, MSHub, to enable auto-deconvolution of gas chromatography–mass spectrometry (GC–MS) data. We then designed workflows to enable the community to store, process, share, annotate, compare and perform molecular networking of GC–MS data within the Global ...
*Drying of natural gas, if COS minimization is essential, or a minimum coadsorption of hydrocarbons is required. *Drying of highly polar compounds, such as methanol and ethanol *Drying of liquid alcohol *Static, (non-regenerative) dehydration of insulating glass units, ...
where F is the atomic force, r is the atom co-ordinate vector, and m is the atom mass. Given the large number of molecules, the workload is too large for analytical algorithms. Therefore, when studying atom velocities and co-ordinates, the finite difference method is usually employed to ...
Such a direct nonadiabatic (DNA) approach, see Section 2.3, accounts strictly for the (nonadiabatic) effects of the finite mass of the nuclei and has been intensively developed in recent years. Such calculations are relatively costly considering a large number of rovibrational states of the ...
Despite kerogen’s importance as the organic backbone for hydrocarbon production from source rocks such as gas shale, the interplay between kerogen’s chemistry, morphology and mechanics remains unexplored. As the environmental impact of shale gas rises, identifying functional relations between its geochem...
