  • Alkylation for Motor Fuels
    The major difference between the two processes lies in their reactor designs — Phillips Petroleum uses a differential-gravity reactor settler, and UOP favors a pumped acid system with a vertical shell-and-tube heat exchanger type reactor. In the H2SO4 acid alkylation process, it is necessary for the alkylation reaction to be carried out …
  • Transport and sorption of 85 Sr and 125 I in crushed crystalline rocks under dynamic flow conditions
    For desorption (displacement) experiments, a mixture of H2SO4 and HNO3, simulating an artificial acid rain, in a … Peristaltic pumps were used for introduction of SGW from reservoirs onto heads of the vertical columns and the vol- umes of the fractions of outflows were registered.
  • Effect of post‐induction nutrient feeding strategies on the production of bioadhesive protein in Escherichia coli
    The concentrations of glucose and acetate in the medium were determined by high-performance liquid chromatography (Hitachi L-3300 RI monitor, L-4200 UV-Vis detector, L-600 pump , D-2500 chromato-intergrator … … using 0.01 N H2SO4 as the mobile phase. … SDS-PAGE) was performed by the method of Laemmli (1970) using a SE600 vertical slab gel unit …

    The ternary H2SO4 /OA/H2O solution droplets homogeneously froze at Sice = 1.38 ( vertical green line), yielding a peak ice parti- cle number concentration of about 80 cm−3. Whereas in the first expansion cooling cycle a fast pump- ing speed (200 m3 h−1) was used to produce a large number of ice crystals that could trigger the precipitation of oxalic acid dihydrate, the pumping speed and thus the humidifica- tion …

  • GGR Biennial Critical Review: Analytical Developments Since 2010
    Hashimoto et al. (2010) used KMnO4 and H2SO4 to oxidise chloride to chlorine gas, which dramatically increased … Zheng et al. (2010) describe a novel thin-film reactor utilising a thin film of sample pumped onto a vertical quartz rod that allows the rapid escape of gener- ated hydrophobic species while simultaneously enabling vapour generation and gas–liquid separation.
