Diphenylmethane (DPM), 9-benzylphenanthrene (BP), di(1-naphthyl)methane (DNM), 1,2-di(1-naphthyl)ethane (DNE), and 9-(1-naphthyl)phenanthrylmethane (NPM) were used as substrates hydrogen-transfer reactions from molecular hydrogen to the examined over an activated carbon (AC) under pressurized at 300 °C. The results show that AC catalyzes monatomic transfer reactivities of toward hydrocracking decrease in following order: NPM > DNM BP ≫ DNE DPM. These can be interpreted by differences...
Abstract UCO ceramic microspheres were fabricated by combination of internal gelation and carbothermic reduction process. The effects the sintering atmosphere C/U ratio on studied. composition, surface morphology, microstructure sintered analyzed. results indicated that increasing CO concentration in could slow down rate reduction, when increased to 20% or above, inhibit reaction, changed obviously became loose. With increase broth, some residual carbon would exist due large size particles....
In this work, several important problems related to the fabrication of ultrafine grained UFG alpha+beta titanium alloys have been investigated, taking Ti-6.5Al-3.3Mo-1.8Zr-0.26Si wt- as model material. It has shown that can be produced by deformation at relatively low temperatures or high strain rates. There were different Zenner-Holloman parameter-grain size relationships in temperature region 750-920C and 650-750C for present alloy. During compression a martensite microstructure 890C, both...
The superplastic deformation behavior of a Ti alloy with submicron grain size was investigated. ultrafine grained (UFG) exhibits good superplasticity at lower temperature (800°C) and higher strain rates (not than 1.8×10 -2 s -1 ). Severe inhomogeneity(DI) could occur certain conditions. To or to raise rate ease eliminate inhomogeneity. influence conditions on DI analyzed. Based examining the m value activation energy UFG alloy, SPD mechanisms were proposed be boundary sliding accommodated by...
AbstractThe quality of molten iron produced by two melting processes, the medium frequency induction furnace process and shortcut duplex with blast furnaces, has been studied comparatively. The contributes to a higher undercooling tendency base iron, extent this depends on other processing parameters such as ratio charges, fluctuation in composition, superheating temperature holding time, etc. When is used production grey cast there are no essential differences, subsequent proper...
ZrCO ceramic microspheres were fabricated by sol-gel combined with carbothermic reduction. The effect of carbon on the physicochemical characteristics was investigated. results indicated that increase content in broth, interior structure sintered would become loose, which led to lowering density and decreasing crush strength microspheres. Crack-free high mass fraction ZrC could be successfully obtained C/Zr = 3 broth at 1550°C for 4h argon containing 5%CO.
In this article, we synthesized some hydrogen-containing polysiloxanes by ring-openging polymerization of cyclosiloxanes and studied their viscosity-average molecular weights (η) active hydrogen content respectively. Then prepared a chiral amide compound condensation reaction acryloyl chloride (1S)-1-phenylethanamine. Subsequently, successfully carried out hydrosilylation with the one polysiloxane. addition, structures target molecules have been confirmed IR 1H NMR spectra, elemental...
