... velocity, density, compressibility, and Joule-Thomson coefficient). A pulse-echo technique was used to measure the sonic velocity in CO2, methane, and their mixtures (containing 5 - 30 mol% CO2) in the pressure range of 1 – 200 bar and in temperaturerange of 300 – 323K. The corresponding density...

... reforming, it is the method that is most frequently used. While other resources are being transformed to produce 30% of the hydrogen needed for the world, methane reforming makes up 48% of the total. The steam reforming process has one of the greatest production efficiencies of all currently commercially...
