A process for converting a hydrocarbon gas (e.g. natural gas) to syngas which, in turn, is converted into a liquid hydrocarbon product wherein a substantial amount of the heat generated in the process is recovered for use in generating s... JR Wolflick,GL Beer,RL Payne - US 被引量:...
"It turns out that for the process ofliquid-to-vaporphase change, a fundamental understanding of that is still relatively limited," Wang explains. "While there's been a lot of theories developed, there actually has not been experimental evidence of the fundamental limits of evaporation physics."...
Liquids and gases are bothfluidsand exhibit resistance to flow through a confined space. But it's interesting (and not often appreciated) that their viscosities have entirely different origins, and that they vary with temperature in opposite ways. Why should the viscosity of a gasincreasewith temp...
it and swing a yoke, which in turn causes a vent valve lever to snap over "dead center" to close the vent valve while opening the gas supply valve to permit gas to flow downward to the porous gas diffuser and thence to flow upward through the liquid so as to charge it with gas. ...
Our attention is focused on solar nebula processes mainly in untangling the origin of the initial liquid droplets that turn into chondrules. To do this, we start deciphering the processes under which the chondritic constituents of glass-rich, PO and POP chondrules from the Unequilibrated Ordinary ...
Conversely, the static methods assume the presence of an elastic response from all the atoms in the material, predicting in turn a stiffer material than it is in reality. For t-LGPS, our results show that such overestimation amounts to ~25–50%, so a proper statistical dynamic treatment ...
Bases: Weak versus Strong Electrolytes: To be thorough we should also mention that bases that dissolve in water are also electrolytes. Here is lye (sodium hydroxide), which disassociates into Na+ and OH-. Quick check for electrolytes: The presence of electrolytes can easily be checked by the...
These were not the first examples of supporting an ionic liquid for catalysis (Mehnert2005). That honour goes to Richard Carlin and Joan Fuller, who incorporated palladium into a gas permeable ionic liquid–polymer gel composed of [C4C1im][PF6]-poly(vinylidene fluoride)–hexafluoropropylene copoly...

into the gas chamber of the membrane chamber II through valve 16 so that the water is pressed out of the membrane chamber during the pressure impulse of the gas. The water may be introduced into the membrane chamber 13, for example from the pipe 6 through a valve 14a and a pressure-...
