Estimating the term…
A catalyst comprising, in its active composition, from 0.05 to 1.0% by weight of at least one metal or compound of a metal of the 10th group of the Periodic Table of the Elements and from 0.05 to 1.0% by weight of at least one metal or compound of a metal of the 11th group of the Periodic Table of the Elements, with the weight ratio of the metal of the 11th group to the metal of the 10th group being from 0.95 to 1.05, and, as support, an SiO2-containing catalyst support having a BET surface area of from 2 to 400 m2/g, wherein at least 20% of the total pore volume of the catalyst is made up by pores having a diameter greater than 100 nanometers, can be used in processes for removing alkynes, dienes and/or monounsaturated hydrocarbons from streams of materials.
A catalyst for removing alkynes, dienes, monounsaturated hydrocarbons and/or oxygen from reaction feed streams or product streams comprising, in its active composition, from 0.05 to 1.0% by weight of palladium or a palladium compound and from 0.05 to 1.0% by weight of silver or a silver compound, with the weight ratio of silver to palladium being from 0.95 to 1.05, and, as support, an SiO2- containing catalyst support having a BET surface area of from 2 to 400 m2/g, wherein at least 20% of the total pore volume of the catalyst is made up by pores having a diameter greater than 100 nanometers.
