“…The three-dimensional (3D) response surface and the two-dimensional (2D) contour projection of the regression equation are graphical representations that aid in the determination of the relationship between two variables and the identification of optimal experimental conditions when the third variable is set to zero levels (Li et al 2020 ). Elliptical contour plots show a significant interaction between variables, whereas circular contour plots indicate non-significant interactions between variables (Sahu et al 2020 ).…”

The response surface methodology (RSM) was used in order to select the extraction conditions of extract from Kentichi date powder; a by-product of the date-processing process. Powder/solvent ratio, extraction temperature, and extraction time all had an impact on sugar yield, and these model factors have quadratic effects influencing sugar yield. Optimal extraction was obtained with 300 g/L powder/solvent ratio, 32.7 °C extraction temperature, and 2.1 h extraction time. Under these conditions, Kentichi date powder's (KDP) sugar yield was 77.1%, which was close to the predicted value of the model (80.50%). The results of Kentichi date powder extract (KDPE) showed that the total sugar content is 160.09 g/L. However, the protein content is 10.31 g/L with a majority of the essential amino acids (essentially glutamic acid (28.39 mg/L) and aspartic acid (9.65 mg/L)). The determination of antioxidant activity of KDPE showed a high activity (DPPH IC 50 = 4.8 mg/mL, ABTS IC 50 = 3 mg/mL, FRAP = 4.70 μmol AAE/mL and, TAA = 18.04 μmol Fe(II)/mL). The results show also that the freeze-drying technique has a lot of potential for producing powder from KDPE with many desirable properties. The findings indicate that KDPE with a high nutritional value could be used as a component for the formulation of functional foods.

“…Carbon materials, such as activated carbon (AC) (Wang H. et al, 2019), carbon nanotubes (CNT) (Figueira et al, 2018), and carbon fiber (CNF) (Chai et al, 2017b), have been widely used as supports of the Ni-based catalysts of the CRM reaction. Because the carbon-based materials usually have lots of advantages, such as large surface areas, excellent stability, chemical inertness, and low cost (Li et al, 2020). Their pore-size distributions and surface functionalities could be readily tuned by controlling specific parameters (Sun et al, 2018).…”

CO 2 reforming of methane (CRM) can effectively convert two greenhouse gases (CO 2 and CH 4) into syngas (CO + H 2). This process can achieve the efficient resource utilization of CO 2 and CH 4 and reduce greenhouse gases. Therefore, CRM has been considered as a significantly promising route to solve environmental problems caused by greenhouse effect. Ni-based catalysts have been widely investigated in CRM reactions due to their various advantages, such as high catalytic activity, low price, and abundant reserves. However, Ni-based catalysts usually suffer from rapid deactivation because of thermal sintering of metallic Ni active sites and surface coke deposition, which restricted the industrialization of Ni-based catalysts toward the CRM process. In order to address these challenges, scientists all around the world have devoted great efforts to investigating various influencing factors, such as the option of appropriate supports and promoters and the construction of strong metal-support interaction. Therefore, we carefully summarized recent development in the design and preparation of Ni-based catalysts with advanced catalytic activity and enhanced anti-coke performance toward CRM reactions in this review. Specifically, recent progresses of Ni-based catalysts with different supports, additives, preparation methods, and so on, have been summarized in detail. Furthermore, recent development of reaction mechanism studies over Ni-based catalysts was also covered by this review. Finally, it is prospected that the Ni-based catalyst supported by an ordered mesoporous framework and the combined reforming of methane will become the future development trend.

“…The research shows that the best addition amount of tungsten is 6.5%. 56 1.5 g ammonia metatungstate was dissolved in 30 ml distillated water, and 10 g activated carbon was immersed in solution. The solid liquid mixture was continuously stirred for 6 h, followed by drying at 110 °C in an oven for 12 h. The carbonized precursor was obtained.…”
