Development of Cigarette Carbonaceous Hydrochar/ZIF-67-Based Fluids for CO2 Capture from a Gas Stream in a Packed Column: Mass-Transfer Performance Evaluation

“…The central composite design (CCD) based on the response surface methodology (RSM) was applied to understand the interactions between the operational parameters with a minimum number of experiments. , The CCD-RSM approach provides a statistical model for the prediction of the response and can help in the optimization of operational parameters. , Four operational parameters were chosen as the independent variables as follows: CC-hydrochar/ZIF-67 loading ( X 1 , g/L), liquid flow rate ( X 2 , L/min), gas flow rate ( X 3 , m 3 /h), and CO 2 initial concentration ( X 4 , ppm), whereas the CO 2 capture efficiency was selected as the response ( Y ). The range and level of the independent variables are listed in Table S1, while the experimental runs provided by CCD and their corresponding response (CO 2 capture efficiency) for each experiment are presented in Table S2.…”

Synthesis of high efficient CS/PVDC/TiO2-Au nanocomposites for photocatalytic degradation of carcinogenic ethidium bromide in sunlight

“…Other methods for the removal of EtBr like activated charcoal, ion-exchange-resin, incineration and bioremediation which depends on the bacterial strains are applied. Heterogeneous photocatalytic approaches such as the advanced oxidation processes have received great attention as an active and efficient performance for the removal of organic pollutants from water under solar light illumination with minimal formation of hazard by-products [6]. Titanium dioxide (TiO 2 ) is one of the most studied photocatalyst materials for various photocatalytic applications such as the photocatalytic degradation of different toxic compounds including organic and inorganic water pollutants [7,8].…”
