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 T_opt(2) - optimum working temperature of the method, which is at least approximately 1°C higher than T_opt(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.
