摘要： The invention provides a catalyst comprising a first catalyst ingredient comprising at least one component selected from the group consisting of Pt, Pd and Ir and oxides thereof. It may further comprise at least one component selected from the group consisting of Au, Ag, Cu, Fe, Sb, Se, Te and Ta and oxides thereof as a second catalyst ingredient. These are supported on at least one component selected from silica-boria-alumina composite oxides or zeolites with a silica-to-alumina molar ratio of more than 30, in an amount from 0.1 to 10 g of the first catalyst ingredient and from 0.01 to 5 g of the second catalyst ingredient, each per one litre of the catalyst, with the second to first ingredient weight ratio being less than 1. The catalyst is used for treating exhaust gases by bringing the exhaust gases containing HCl and dioxines into contact with the catalyst thereby eliminating dioxines contained in the exhaust gases by oxidative decomposition while suppressing additional formation of dioxines from precursors for dioxines present in the exhaust gases.

摘要： PURPOSE:To obtain a catalyst reduced in the lowering of catalytic activity even if used for a long time at the normal temp. and excellent in ozone decomposing capacity and durability by supporting at least amorphous manganese oxide and palladium oxide on silica/boria/alumina multiple oxides. CONSTITUTION:An ozone decomposing catalyst is constituted by supporting at least amorphous manganese oxide and palladium oxide on silica/boria/alumina multiple oxides. Oxide of at least one kind of an element selected from a group consisting of Ag, Ir, La and the others may be added to the catalyst. Further, the catalyst is supported with a carrier having a monolithic structure. Gas containing ozone is brought into contact with the catalyst to decompose ozone in the gas. At this time, a sulfur compd. and/or moisture is allowed to coexist in the gas containing ozone. By this constitution, a catalyst reduced in the lowering of catalytic activity even if used for a long time at the normal temp. and excellent in ozone decomposing capacity and durability is obtained.

摘要： PURPOSE:To obtain an inexpensive easily regenerable and repeatedly usable adsorbing material capable of adsorbing CO in inert gas in the vicinity of the normal temp. in an adsorption column by supporting a specific amount of Pd and a specific amount of a second oxide component on a non-combustible carri er. CONSTITUTION:An adsorbing material adsorbing CO in inert gas is produced by supporting 2-80g/l of at least one kind of oxide of an element selected from a group consisting of group I-b copper, silver and gold, group II Mg, Ca, Sr, Ba and Zn, group III B, Ga, In, Sc, Y and lanthanides, group IV Ge, Sn, Ti and Zr, group V Sb, Bi, V, Nb and Ta, group VI Te, Po, Cr and W, group VII-a Mn, Tc and Re and group VIII iron, Co and Ni and 2-85g/l of Pd on a carrier in an amount of 87g/l or less in total. As a result, by treating inert gas with a CO concn. of 1000ppm with this adsorbing material, the CO concn. can be reduced to 1ppm or less.
