     Abstract of a paper presented at the 3d annual meeting of the Chemical Institute of Canada.  A preliminary report is made indicating a method and the apparatus used in the evaluation of catalysts for the reaction of CO and H₂.  The apparatus consists of 6 semi-pilot-scale catalyst-testing units.  Shows some typical results.  Also describes apparatus on which the surface area, the rate of carbiding with CO, and the rate of reduction of the carbide with H₂, are measured on the catalysts.
