Claim Text:
1. Activated carbon particles comprising an activated carbon provided with catalytic or reactive constituents, wherein the activated carbon is in the form of discrete activated carbon particles having a spherical or grain shape, where the activated carbon has particle sizes in the range from 0.01 to 2 mm, as determined according to the method of ASTM D2862-97/04; wherein the activated carbon has a total pore volume in the range from 0.7 to 2.5 cm wherein the activated carbon has a specific BET surface area in the range from 500 m wherein the activated carbon is provided with at least one metal component, wherein the metal component comprises at least one metal-containing ionic liquid (IL) comprising at least one metal compound dissolved or dissociated in the ionic liquid (IL), wherein the metal compound comprises at least one metal selected from the group consisting of Cu, Ag, Au, Zn, Hg, Sn, Ce, Ti, Zr, V, Nb, Cr, Mo, W, Mn, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and Pt; wherein the ionic liquid (IL) is selected from the group consisting of: where the cation of the ionic liquid (IL) is selected among nitrogen-containing cations selected from the group consisting of quaternary ammonium cations, imidazolium cations, pyridinium cations, pyrazolium cations and triazinium cations and phosphorus-containing cation in the form of a phosphonium cation and where the anion of the ionic liquid (IL) is an organic or inorganic anion; and wherein the activated carbon comprises the metal-containing ionic liquid (IL) in amounts of from 1% by volume to 70% by volume, based on the volume of the activated carbon; or wherein the amount of metal-containing ionic liquid (IL), determined as the pore-filling degree α, is such that 20% to 95% of the pore volume of the activated carbon is not filled with the metal-containing ionic liquid (IL), wherein the pore-filling degree α is determined according to the formula [α=V
