A solid composition is prepared by mixing water, a hydraulic cement, aluminum metal powder, and a catalyst composition comprising (a) an inorganic support, (b) Pt and/or Pd metal (c) and 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. The thus-prepared solid compositon can be used as a CO oxidation catalyst.

Cement-containing catalyst composition and process for its preparation

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.

A composition of matter comprises (a) a titania-containing support material, (b) platinum metal, (c) iron oxide, and (d) at least one alkali metal compound (preferably potassium compound). The composition of matter is used as catalyst in the reaction of carbon monoxide and free oxygen to carbon dioxide.

Catalyst composition for the oxidation of carbon monoxide

Esters are prepared by contacting, under suitable reaction conditions, a feed stream comprising a primary alcohol of 1-4 carbon atoms per molecule (preferably methanol, ethanol) and carbon monoxide with a catalyst composition comprising (a) copper or a copper compound (preferably CuO), (b) zinc oxide, (c) at least one metal or compound of at least one metal selected from the group consisting of cobalt, ruthenium, iridium, platinum, molybdenum, and rhenium (preferably cobalt and/or rhenium) and, optionally, (d) alumina.

A process for producing higher ketones comprises the step of contacting under suitable conditions a feed comprising at least one C.sub.2 -C.sub.6 aliphatic aldehyde, and preferably also carbon monoxide, with a catalyst composition comprising (i) copper and/or an oxide thereof and (ii) zinc oxide. Preferably, the feed aldehyde is propanal, and the product comprises at least one C.sub.5 ketone. Ketones are substantially absent from the aldehyde feed.

Synthesis of ketones from aldehydes

A process of producing higher ketones comprises the step of contacting under suitable conditions a feed comprising (a) at least one C.sub.3 -C.sub.6 aliphatic ketone, (b) at least one C.sub.2 -C.sub.6 aliphatic aldehyde and, preferably, also (c) carbon monoxide with a catalyst composition comprising (i) copper or an oxide thereof and (ii) zinc oxide. Preferably, the feed ketone is methyl ethyl ketone, the feed aldehyde is propanal, and the product comprises at least one C.sub.7 ketone.

Synthesis of higher ketones

Higher ketones prepared by contacting under suitable reaction conditions a feed stream comprising (a) a lower ketone having 3-5 carbon atoms per molecule and (b) carbon monoxide with a catalyst composition comprising copper oxide, zinc oxide and, optionally, alumina. The formed higher ketones contain at least one carbon atom per molecule more than the lower feed ketone, preferably methyl ethyl ketone.

Higher ketones are prepared by contacting, under suitable reaction conditions, a feed stream comprising (a) a primary alcohol of 2-6 carbon atoms per molecule (preferably ethanol, 1-propanol or 1-butanol) and (b) carbon monoxide with a catalyst composition containing copper oxide, zinc oxide and, optionally, alumina.
