A paint composition comprising a powder paint uniformly dispersed in an aqueous solution of a water soluble carboxylated resin. Use is made of a powder paint having a mean particle size of 1-100 microns and preferably comprising a thermosetting resin as the vehicle. This paint composition contains no surfactant but, nevertheless, features high stability of the dispersion phase and can provide paint films of excellent resistance to water. This paint composition may utilize recovered waste powder paint, i.e. a mixture of differently colored powder paints, preferably with the addition of a black pigment such as carbon black.

A mixture is prepared by mixing alumina sol and activated alumina which contains not less than 60 Wt % of delta-alumina. The mixture is thereafter coated on a relatively small specific surface area monolithic catalyst carrier. After being dried, the coated carrier is fired to give a high specific surface area catalyst carrier.

Method for forming activated alumina coating on refractory article and

A catalyst is prepared by firstly impregnating a carrier with a solution of a catalytically active metal compound and a sulfur compound and thereafter treating the impregnated carrier in a stream of high temperature steam.
