WebThe rate of this reaction increases at higher temperatures, making the FEHX especially vulnerable. Elimination of feed streams with high di-olefin content is an easy way to reduce fouling but may not be preferred economically. If long periods of operation with high di-olefins content are expected, an option to avoid high fouling rates could be ...

The metal-hydrogen system : basic bulk properties
WebJun 6, 2006 · The structural and magnetic properties of the FeH x (x=0.25; 0.50; 0.75) compounds have been studied using the projector augmented wave (PAW) method … in which V FeHX and V Fe are unit cell volumes of iron hydride and pure iron metal, respectively, and ΔV H is a predetermined volume expansion due to a single formula unit of interstitial hydrogen. The basis for these approximations is the interstitial volumes associated with other 3d -transition metal hydrides or deuterides (e.g., CoH; Fukai ... jfkfoundation.org
Hydrogen in molten iron at high pressure: The first measurement
Web"Bonjour, greetings I am madam Elise and i am the chief engineer at the Fabrication électronique et hardware des Moulineaux or FEHX for short, and today I am here to give … WebJun 6, 2006 · The structural and magnetic properties of the FeH x (x=0.25; 0.50; 0.75) compounds have been studied using the projector augmented wave (PAW) method within the generalized gradient approximation (GGA). We compare the hcp, dhcp and fcc structures and find that for the considered concentrations of hydrogen the hcp structure … WebHere we synthesized hcp FeHx (x<1) in a diamond anvil cell (DAC) using a liquid hydrogen-introducing system and directly measured the longitudinal wave velocity of hcp FeHx (x<1) by femtosecond pulse laser pump-probe technique combined with DAC. The hydrogen concentration of synthesized hcp FeHx (x<1) was estimated to be x=0.15 and x=0.25 … jfk fox nation
