摘要: Disclosed is a method for providing improved hydrogenation activity by pretreating a catalyst in a three-step manner before selective hydrogenation of unsaturated hydrocarbons in an aromatic fraction in the presence of an oxide-type bimetallic (nickel-molybdenum) supported catalyst. The pretreatment of the catalyst comprises sulfidation, oxidation at a temperature above 250°C and reduction.

摘要: Disclosed are a catalyst and a preparation method therefor, the catalyst being able to maintain a high production yield of C8 aromatic hydrocarbons in the process of converting a feedstock containing alkyl aromatics to C8 aromatic hydrocarbons such as mixed xylene through disproportionation/transalkylation/dealkylation while reducing a content of ethylbenzene in the products.

摘要: The present invention relates to a single process for producing hydrogen, carbon monoxide, and carbon from methane by forming gas products comprising hydrogen and carbon monoxide, and solid products comprising carbon and an iron-based catalyst from methane in a methane-containing feedstock through pyrolysis route involving auto-thermal reduction in a rotary kiln-type reactor in the presence of an iron-based catalyst and separating and recovering respective products.
