On the basis of b-FeOOH, Fe(OA) 3 , Fe 3 O 4 iron and spherical catalysts NiO/SiO 2 , Fe 2 O 3 /SiO 2 derived from slag waste coals of heating electrical stations, the hydrogenation of model polycyclic hydrocarbon at presence of nanodimensioned catalysts antracene was studied. On the example of conversion of anthracene, it was shown that upon release of hydrogenation of the product yield and degradation of polycyclic hydrocarbons in the hydrogenation, the mentioned catalyst systems appeared to be in the following order: nanoparticles b-FeOOH, Fe(OA) 3 and Fe 3 O 4 [spherical catalysts NiO/SiO 2 , Fe 2 O 3 /SiO 2 [commercial cobalt-molybdenum catalyst. The results showed that the catalysts studied are promising catalysts for the hydrogenation of polycyclic hydrocarbons and may be used for direct coal liquefaction.
The hydrogenation of anthracene in the presence of the nanosized catalysts based on iron β FeOOH and Fe(OA) 3 (OA refers to oleic acid) and the spherical catalysts NiO/SiO 2 and Fe 2 O 3 /SiO 2 obtained from ash and slag from thermal power plants was studied. It was found that the above catalytic systems can arranged in the following order according to the yields of hydrogenation and destruction products upon the hydrogenation of polycyclic hydrocarbons: β FeOOH, Fe(OA) 3 , and Fe 3 O 4 nanoparticles > NiO/SiO 2 and Fe 2 O 3 /SiO 2 spherical catalysts > commercial cobalt-molybdenum catalyst. It was established that the test catalysts are promising for the hydrogenation of polycyclic hydrocarbons, and they can be used for the direct liquefaction of coal.
The kinetic and thermodynamic parameters of the hydrogenation of an anthracene-ben zothiophene model mixture were calculated. The rate constants of forward and reverse reactions, the equilib rium constant, the activation energies, and the heat effects of hydrogenation reactions were determined by equi librium kinetic analysis for second order reactions in a model mixture of anthracene and benzothiophene in the presence of an iron containing catalyst over a temperature range of 648-698 K at a pressure of 6 MPa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
