In refineries hydrogen is an essential utility to prepare clean transportation fuels. It is not only used for hydro treatment of finished products, but also for deeper hydro conversion of heavier and sourer crude fractions, for instance in hydrocrackers. In most refineries a hydrogen plant is ...

Thus, this hydrogen value is used in this paper production methods must meet. When the pricing of 1 kWh of electric energy is lower due to the availability of a cheap energy source (e.g., from solar or wind farms), the DOE's target will be more advantageous for the new methods. ...

Five methods for preparation of hydrogen‐producing seeds (base, acid, 2‐ bromoethanesulfonic acid (BESA), and load shock and heat shock treatments) as well as an untreated anaerobic digested sludge were evaluated for their hydrogen production perform‐ ance and responsible microbial community ...
The molecule-like bimetallic cluster may thus provide a platform for the discovery of finely tuned catalysts, which could have broad implications for catalysis beyond H2 production. Methods Electrochemical methods. SWV and LSV were conducted with an electro- chemical workstation (model 660B; CH ...

Methods Materials and sample preparation. MRM was prepared by acid digestion of RM in 6M HCl at 220 °C, as described elsewhere30. In summary, RM was treated with HCl 37% (Merck) in a microwave digester (Milestone Microwave Digestion System (SK-10) with temperature control, operating...
Methods Ion production The ions produced in the EBIT are already rather slow (7 keV × Nq, withNqas the charge state), which simplifies the capture of ions after ejection. In a pulsed drift tube, the kinetic energy is reduced to roughly 500 eV × Nq, which is low enough ...
