Abstract: Carbon nanofiber doped alumina (Al—CNF) supported MoCo catalysts in hydrodesulfurization (HDS), and/or boron doping, e.g., up to 5 wt % of total catalyst weight, can improve catalytic efficiency. Al—CNF-supported MoCo catalysts, (Al—CNF—MoCo), can reduce the sulfur concentration in fuel, esp. liquid fuel, to below the required limit in a 6 h reaction time. Thus, Al—CNF—MoCo has a higher catalytic activity than Al-MoCo, which may be explained by higher mesoporous surface area and better dispersion of MoCo metals on the AlCNF support relative to alumina support. The BET surface area of Al-MoCo may be 75% less than Al—CNF—MoCo, e.g., 166 vs. 200 m2/g. SEM images indicate that the catalyst nanoparticles can be evenly distributed on the surface of the CNF. The surface area of the AlMoCoB5% may be 206 m2/g, which is higher than AlMoCoB0% and AlMoCoB2%, and AlMoCoB5% has the highest HDS activity, removing more than 98% sulfur and below allowed levels.

Abstract: Provided herein is a novel silica-supported nickel nanocomposite and a novel one-pot solution combustion synthesis of that nanocomposite. The method allows the synthesis of small size nickel nanoparticles (e.g., 3 nm to 40 nm) for which a considerable percentage of nickel is inserted into silica, experiencing strong metal-support interaction. These exceptional physicochemical properties make them desirable for various industrial applications, such as electronic, heterogeneous catalysis as well as conversion and storage of energy.

Abstract: Particles for an exhaust gas purification catalyst including: inorganic oxide particles; and an inorganic coating layer covering the inorganic oxide particles. The particles for an exhaust gas purification catalyst have reduced cumulative pore volume in a pore diameter range of 0.1-20 μm compared to a cumulative pore volume in a pore diameter range of 0.1-20 μm of inorganic oxide particles before being coated with the inorganic coating layer. Accordingly, the particles for an exhaust gas purification catalyst have a higher thermal conductivity than the inorganic oxide particles before being coated with the inorganic coating layer.

The catalyst includes a zero-valent iron and phosphorus co-modified carbon material which includes a carbon material as a carrier, a zero-valent iron supported onto the carrier and serving as an active component, and a phosphate functional group formed on the surface of the carbon material. The preparation method includes: co-modifying a carbon material using a ferric salt and organic phosphorus to obtain the catalyst for continuous production of 1,1,1,3-tetrachloropropane through gas-solid reaction. The present application further provides a method for continuous production of 1,1,1,3-tetrachloropropane through gas-solid reaction. The catalyst provided in the present application integrates active component zero-valent iron and auxiliary component phosphate functional group on the carbon material, thereby realizing the continuous production of 1,1,1,3-tetrachloropropane on a gas-solid fixed bed reactor.
