In the method proposed, the gas or gas mixture under analysis is passed through at least one support (5) in which at least one acoustic or ultrasonic transmitter or receiver cell (S1, S2) is located, preferably at an angle to the axis of the tube, to form a measurement path. The ...
JamesSpeight, inShale Oil and Gas Production Processes, 2020 4.5Molecular weight Themolecular weight(formula weight) of a compound is the sum of the atomic weights of all the atoms in a molecule and can be determined by a variety of methods. Crude oil, being a complex mixture of (at least...

Gas-water two-phase flow mechanism of CO2/CH4 in moist nanoporous media is significant in carbon capture and storage (CCS) and enhanced oil and gas recovery (EOR) technology. However, in untraditional oil and gas exploitation, the flow property of CO2/CH4-H2O mixtures are neglected in shale ...
e.g., methane, ethane, and propane, are gases; those of intermediate molecular weight, e.g., hexane, heptane, and octane, are liquids; and those of high molecular weight, e.g., eicosane (C20H42) and polyethylene, are solids. Paraffin is a mixture of high molecular weight alkane deriv...
Thermogravimetric analysis (TGA) revealed the removal of guest molecules at 383 K, and demonstrated structural stability up to 473 K under N2atmosphere (Supplementary Fig.6). The permanent porosity of activated SOFOUR-DPDS-Ni was probed by CO2gas sorption isotherms at 195 K, and the Brun...
supplying an appropriate gas ( mixture of inert gas and molecular oxygen) for storing (meth)acrylate into the tank, in which the tank is made of a carbon steel material; the gas has a water concentration of 100 ppm or less; and the (meth)acrylate has a (meth)acrylic acid concentration ...
A high activity of 157.5 mmol h−1 g−1 was also achieved under AM 1.5G irradiation. We also measured the catalytic activity for a physical mixture of individual nanoparticles (MTPA-CA and CNP147), which displayed a much lower HER of 66.6 mmol h−1 g−1, showing ...
The adsorption properties of wood carbonized at various temperatures were investigated using a mixed gas containing toluene and α -pinene. Hinoki ( Chamaecyparis obtusa ) samples carbonized at 500°–1100°C were exposed to gas mixtures of toluene and α -pinene at 20°C. The samples carbonized...
