FIELD: chemistry. ^ SUBSTANCE: described is a catalyst composition for oxychlorination of hydrocarbons which contains a catalytically effective amount of an oxychlorination catalyst and a diluent which contains aluminosilicate particles, where average size of the particles of the catalyst and diluent ranges from 5 to approximately 300 micrometres. Described is a catalyst composition for oxychlorination of hydrocarbons which contains the following: (a) a catalytically effective amount of an oxychlorination catalyst, having surface area greater than 25 m2/g, in which the oxychlorination catalyst contains support material in which an active salt composition is distributed; and (b) a diluent having surface area from approximately 0.1 m2/g to approximately 25 m2/g, in which the support material and the diluent are chemically different, and average size of particles of the catalyst and diluent ranges from approximately 5 to approximately 300 micrometres. Also described is a method for oxychlorination of hydrocarbons, involving a step for bringing reagents containing hydrocarbons, a chlorine source and an oxygen source into contact with the oxychlorination catalyst composition in conditions for the method to obtain chlorinated hydrocarbons. Also described is a method for oxychlorination of hydrocarbons, involving a step for bringing reagents containing hydrocarbons, a chlorine source and an oxygen source into contact with one of the catalyst compositions described above, containing a catalytically effective amount of an oxychlorination catalyst and an inert diluent under conditions of the method to obtain chlorinated hydrocarbons, in which the method is realised at Topt(2) - optimum working temperature of the method, which is at least approximately 1C higher than Topt(1) - the optimum working temperature of the method which uses the same reactor, the same reagents, amount of loading the reactor, productivity standards and oxychlorination catalyst, but without an inert diluent. ^ EFFECT: attaining higher reaction temperatures without detriment to other vital parametres of the oxychlorination process. ^ 31 cl, 11 tbl, 9 ex, 8 dwg |
