Abstract
Active-alumina carriers for catalyst are prepared by reacting aqueous sodium aluminate solution with nitric acid, the concentration of reagents, precipitation temperature and pH being controlled so that the precipitate, after washing and drying, has a nitrate content of 10 to 30% calculated as NO3 based on the weight of Al2O3, and subsequently annealing the precipitate at temperatures above 400 DEG C. In examples, dried precipitates are obtained, plasticized with nitric acid as peptizing agent, shaped into balls and heated at 450 DEG C.; in another example the precipitate is mixed with alumina sol and hexamethylene tetramine solution, dropped into hot oil, and the resulting balls aged in hot hexamethylene tetramine solution, dried and heated at up to 500 DEG C.ALSO:Active-alumina carriers for catalysts are prepared by reacting aqueous sodium aluminate solution with nitric acid, the concentration of reagents, precipitation temperature and pH being controlled so that the precipitate, after washing and drying, has a nitrate content of 10-30% calculated as NO3- based on the weight of Al2O3, and subsequently annealing the precipitate at temperatures above 400 DEG C. In examples dried precipitates are obtained, plasticized with nitric acid as peptizing agent, shaped into balls, heated at 450 DEG C., and converted into catalysts by saturating with (a) a solution of potassium dichromate and chromic acid, and with (b) chloroplatinic acid, drying and heating at 450 DEG C.; in another example the precipitate is mixed with alumina sol and hexamethylene tetramine solution, dropped into hot oil, and the resulting balls aged in hot hexamethylene tetramine solution, dried, heated at up to 500 DEG C., saturated with chloroplatinic acid, dried and heated at 450 DEG C. The catalysts are used to convert n-butane to butene, to convert n-heptane to toluene, and to reform "straight-run" petrol.
