ABSTRACT:
A solid composition is prepared by mixing water, a hydraulic cement, sodium silicate, and a catalyst composition comprising (a) an inorganic support, (b) Pt and/or Pd metal and (c) Fe metal and/or oxide, followed by maintaining the obtained mixture under such conditions as to affect hardening of the hydraulic cement. Preferably, the hydraulic cement is a Type III portland cement and/or a Class H well cement. A solid composition comprising hydraulic cement, sodium silicate and the above-described catalyst composition is provided. This solid composition can be used as a CO oxidation catalyst.
