摘要

"The composition of catalyst for selective hydrogenation, selective hydrogenation process of compound Acetylenics, and method of preparation of a composition for selective hydrogenation catalyst.Catalysts for hydrotreating Ni more selective and efficient are those containing more than about 60% of the nickel content in the peripheral surface of the porous media.Such as alumina extruded.That can be obtained by spraying a solution of a nickel compound dispersed on the support, and drying the same at a temperature in the range of 200 to 600 198 C.When used, for example,To remove compounds Acetylenics currents of butadiene is obtained a greater recovery of butadiene content and low acetilu00eanico desired with less deposition of polymers, heavyThan was possible with the previous catalysts.
