7, rhamnolipid was capable of fully emulsifying the light crude oil up to the 5th cycle performed (it is very likely that it will be able to undergo many more cycles). Additionally, the crude oil can be fully recovered within 1 h of H2SO4 addition in each cycle. This performance ...
c, In-situ catalytic cycle. Reaction conditions: 100 mg catalyst, 80 °C, 3.2 MPa (CO/C2H2/Ar = 6:5:89), 10 ml H2O. The reaction was cycled by charging new feed gas into the system without separating the catalyst and solution. TOF is calculated as specific mole rate of ...
This paper aims to analyse the scientific production that deals with the study of groundwater’s Life Cycle Assessment (LCA), using bibliometric methods. Thus, it contributes to the evolution of knowledge of this resource in terms of its use (environmental, economic and social). The ...
(3) Water cycle through push pump Due to the stagnation phenomenon of the partial wading area, we consider the use of a push pump at the corner of the Shuijie 1–2 section and Moya area (Figure 7). The design flow of the push pump is 0.2 m3/s. The stream is pushed through to ...
For example, a dry air cooling system for a natural gas combined cycle generator consumes and withdraws 0.00–0.02 L/kWh, whereas a wet cooling (open recirculating) system for a coal steam turbine consumes 0.53 L/kWh and withdraws 132.5 L/kWh. Efficiency varies significantly, ...
The age control on the marine sediment record was provided by 11 accelerator mass spectrometry (AMS) radiocarbon dates on mollusc shells (Supplementary. Table1) at the Keck Carbon Cycle AMS Facility, University of California, Irvine, US, and210Pb/137Cs measurements conducted on 20 samples at the...
The successive time interval is 30 min for each cycle [31]. 2.6.11. Effect of saline environments In investigate the salt solution effect; hydrogel specimens were emerged into saline solutions (NaCl, CaCl2 and AlCl3) with different ionic strength according to the above mentioned method. 2.6....
