20% Pt/pearly black and 20% Pt/acetylene black can achieve average hydrogen generation rates of 1.9 L/min and 2.3 L/min,respectively,which can give hydrogen supply for a 308 W proton exchange membrane fuel cell(PEMFC) and a 373 W PEMFC at 100% hydrogen utilization.
The article probes into development status and trends of refinery hydrogen production technology, analyzes the source of refinery hydrogen and the approach to acquire cheap hydrogen resources and points out that we should strengthen optimal management of refinery hydrogen resources application and devote major efforts to develop, popularize and apply heavy hydrocarbon feedstock hydrogen production process.
Hydrogen production from co-gasification of coal and biomass in supercritical water by continuous flow thermal-catalytic reactio
The influences of temperature, pressure and concentration on hydrogen production from co-gasification of coal and CMC in SCW under the given conditions (20-25 MPa, 650°C, 15-30 s) are discussed in detail.
The higher pressure and higher CMC content facilitate hydrogen production; production is decreased remarkably given a longer residence time.
Molecular characterization and fermentative hydrogen production of a wild anaerobe in clostridium genus
With thinner membrane and higher sweep ratio, methane conversion rate increases with high reforming pressure, which will change the unfavorable condition of high pressure of HTGR methane reforming hydrogen production system into a favorable one.
In the CoMSIA model, steric, electrostatic, hydrophobic and hydrogen bond donating factors were correlated to the activity and later the favorable and unfavorable regions of interaction were obtained.
tripos standard, hydrogen bonding, parabolic indicator in the case of CoMFA and steric, electrostatic, donor, acceptor, hydrophobic, donor and acceptor, steric and electrostatic in the case of CoMSIA.
Flavonoid antioxidants act as scavengers of free radicals by rapid donation of a hydrogen atom.
In addition, electrostatic, hydrogen-bonding, and dipole-dipole interactions are responsible for the above separations, which improve the selectivity of DNB for solutes.
Both metalation reaction with n-butyllithium and hydrochlorination reaction with dry hydrogen chloride selectively and quantitatively occurred at the pendant reactive sites, generating polymeric benzyllithium and 1-chloroethylbenzene species.
Because of this photoelectron transfer mechanism, the HPA-entrapped TiO2-Y-zeolite has demonstrated the synergistic enhancement of the photocatalytic decomposition of Methyl Orange and hydrogen generation from photolysis of water.
pneumoniae, acetoin and 2,3-butanediol, was favoured by glycerol excess, while hydrogen generation and ethanol formation were best under glycerol limitation.
Properties of TiO2 as photoelectrode for hydrogen generation using solar energy
One of the major barriers to the introduction of the hydrogen economy and its wider acceptance is the lack of the rather costly hydrogen generation, transportation and distribution infrastructure to meet the local transport fuel demands.
In this paper, the development of polymer electrolyte membrane electrolysis technology for on-site, on-demand hydrogen generation has been discussed.
