CATALYST, PREPARATION METHOD THEREOF AND METHOD OF DECOMPOSING CHLORINE-CONTAINING HYDROCARBONS Russian patent published in 2011 - IPC B01J23/755 A62D3/00 B01J21/02 B01J21/18 B01J23/70 B01J23/72 B01J37/00 B01J23/26 B01J21/06 

FIELD: chemistry.

SUBSTANCE: invention relates to heterogeneous catalysis. Described is a catalyst for decomposing chlorine-containing hydrocarbons or mixtures thereof, containing dispersed active particles of nickel attached to carbon fibres with diameter 0.1-0.4 mcm. Described also is a method of preparing the described catalyst, characterised by that the starting raw material for preparing said catalyst is solid articles made from nickel, for example in form of a tape, wire etc, and pairs of halogen-substituted hydrocarbons in a mixture with hydrogen are used to mould dispersed active particles from solid metal articles. Described also is a method of decomposing chlorine-containing hydrocarbons or mixtures thereof, involving catalytic conversion of thereof into carbon, hydrogen chloride and hydrogen in the presence of the described catalyst.

EFFECT: catalyst is resistant to deactivation in aggressive conditions and provides high output of carbon fibres during decomposition of chlorine-containing hydrocarbons or mixtures thereof.
