Abstract: A conditioning process that is employed with a high selectivity catalyst (HSC) during an initial phase (i.e., start-up) of the epoxidation process is provided. The HSC conditioning process of the present disclosure ensures that the heat release from a catalyst bed containing an HSC during a start-up operation is less than 2000 kJ/Kgcat·hr. The HSC containing catalyst bed that has been conditioned by the process of the present disclosure exhibits improved performance (i.e., EO selectivity) and reduced hot spots.

Abstract: Disclosed are a photocatalyst and application thereof in environmentally friendly photocatalytic treatment of a power battery. The photocatalyst is obtained by loading Ag—TaON on a hollow glass microsphere, wherein a mass ratio of the Ag—TaON to the hollow glass microsphere is 1:5 to 10. According to the invention, the Ag—TaON and the hollow glass microsphere are compounded, the hollow glass microsphere has better light permeability, which avoids mutual shielding between catalysts, such that the photocatalyst filled in a reactor is fully excited, which is capable of effectively improving a light utilization rate, thus improving the catalytic conversion efficiency of the photocatalyst.

Abstract: A supported catalyst having rhodium particles with an average diameter of less than 1 nm disposed on a support material containing magnetic iron oxide (e.g. Fe3O4). A method of producing the supported catalyst and a process of reducing nitroarenes to corresponding aromatic amines employing the supported catalyst with a high product yield are also described. The supported catalyst may be recovered with ease using an external magnet and reused.

Abstract: Provided is a catalyst for oxidative dehydrogenation, a method of preparing the catalyst, and a method of performing oxidative dehydrogenation using the catalyst. The catalyst for oxidative dehydrogenation has improved durability and fillability by including a porous support coated with a metal oxide (AB2O4) according to Equation 1:

X wt %+Y wt %=100 wt %,  



wherein X is a content of AB2O4 and is 5 or more and less than 30, and Y is a content of the porous support and is more than 70 and 95 or less,

wherein the metal oxide exhibits activity during oxidative dehydrogenation. Therefore, when the catalyst is used in oxidative dehydrogenation of butene, the conversion rate of butene and the selectivity and yield of butadiene may be greatly improved.
