Hangkong Dongli Xuebao/Journal of Aerospace Power. The possible reaction paths of phenol during subcritical hydrothermal conversio, ing Equation (8) to fit them, the values of, a correlation between the predicted value and the. Catalytic conversion of substituted and un-substituted cyclohexanone into corresponding enones and phenols by nanocatalysts under acid or base-free reaction conditions. loading amounts had different physicochemical properties (e.g., particle size, specific surface area. Compared with thermophilic digestion of FVR, thermophilic digestion of 160°C treated FVR, and thermophilic digestion of WVR with mesophilic digestion of WL, the thermophilic digestion of 160°C treated WVR with mesophilic digestion of WL obtained the maximum total methane yield of 102.5L/kg FVR. Hydrogenation catalyst is of major importance in the production of eco-friendly oxidant hydrogen peroxide. At the same time, the conversion of phenol is only 47% and no gas products are formed at all. © 2020 Hydrogen Energy Publications LLC. Insert Equation (7) into Equation (6), and obtain: beginning time of the reaction, respectively. The XPS spectra, observed shift in the binding energy verified that the electronic properties of Ni metal wer, energies at 872.92 and 879.49 eV were attributed to the main line of Ni, which proved the presence of both metallic Ni and NiO on the surface of the support. The HDO of phenol was found to be favored on the bifunctional Rh/C and Ni/AC catalysts which exhibit a large amount of well dispersed metallic species (from HRTEM). ), catalysts greatly limits their industrial applications, which also drives researchers to find alternative, metal-based catalysts (e.g., Ni-, Cu-, and Co-based, etc.) , which indicated the characteristic peaks of (220), (311), (222). It was found that a nearly complete gasification of phenol can be achieved even at a low temperature of 450 °C with the bimetallic nanoparticles catalysts. FTIR and EDX analysis showed that the amino benzoic acid and chromium had been incorporated into the silica matrix which resulted in nano-sized pores in RH-Cr-A. The conversion of phenol, cyclohexanol (a hydrogenated analog of phenol for comparison with phenol), and ethanol into gas products in supercritical water (SCW) was studied with the goal to compare the reactivity of their aqueous solutions with the structural features obtained by the method of classical molecular dynamics. ; Alamdari, H.; Kaliaguine, S. Effect of alkali additives over nanocrystalline. The alloying of Ni and the second metal (i.e., Co) may lead to the change of the catalyst, particles were chosen for the analysis of the selective conversion kinetic, behaviors of phenol into cyclohexanol in the rest of the study, characterized. At the same time, the conversion of phenol is only 47% and no gas products are formed at all. Thermogravimetric analysis (TGA), Ultraviolet-Raman (UV-Raman), and Brunauer−Emmett−Teller (BET) characterization of catalysts used in the hydrotreatment of single and mixed model compounds demonstrated that this phenomenon did not mainly arise from the irreversible deactivation of catalysts caused by carbon deposition, but the competitive adsorption among hydroxyacetone, furfural, and phenol during the mild hydrotreatment of mixed model compounds. According to Huelsman’s study [32], 2.4. Then, a catalyst, with optimal activity (i.e., 15 wt%Ni–3Co/, ) was selected and used for selective conversion.
