  • GC/MS analysis of a complex sample in DCM using hydrogen carrier gas

    Labs worldwide have recently found that helium has been in short supply, leaving a number of labs without carrier gas. Added to this, helium prices have doubled over the past 10 years causing a number of labs to look into alternative carrier gases for GC, such as nitrogen and hydrogen. As well as lower price and unlimited availability, hydrogen has a number of potential advantages over helium, ...

  • Conversion of food waste into hydrogen by thermophilic acidogenesis

    Conversion of food waste into hydrogen by thermophilic acidogenesis was investigated as a function of organic loading rate (OLR), hydraulic retention time (HRT) and pH in a continuous stirred tank reactor. In order to identify hydrogen-producing microorganisms, denaturing gradient gel electrophoresis (DGGE) of the polymerase chain reaction (PCR) – amplified V3 region of 16S rDNA analysis was ...

  • Energy and exergy analyses of a steam reforming process for hydrogen production

    Hydrocarbon steam reforming is an important process for hydrogen production. In petroleum refineries, steam reforming is most commonly used for hydrogen production from naphtha and light hydrocarbon gases (methane, ethane and propane). Since the hydrocarbon steam reforming system is one of the highest energy intensive systems in a petroleum refinery it should be directed to a more efficient use ...

  • Removal of hydrogen sulphide on sewage sludge/industrial sludge based carbonaceous adsorbents

    The adsorbents were prepared for sewage sludge, waste oil sludge and metal oil sludge. On the materials obtained dynamic adsorption of H2S was measured. The initial and exhausted adsorbents were characterised using sorption of nitrogen, thermal analysis, and XRF, XRD and surface pH measurements. The adsorbents have high capacity for H2S (10% wt) The high volume of mesopores contributes ...
