FIELD: chemistry. ^ SUBSTANCE: invention relates to heterogeneous catalysis and can be used to recycle hydrocarbons and halogen-substituted hydrocarbons when producing composite materials, catalysts, sorbents and filters. Catalytic pyrolysis of hydrocarbons is carried out at 500-700C on a catalyst obtained by dispersing articles of solid nickel and alloys thereof with other metals, e.g., iron, chromium, as a result of reaction with 1,2-dichloroethane vapour. The catalyst contains dispersed active nickel particles attached to carbon nanofibres with diameter 0.1-0.4 mcm. The starting material used is bromine- or chlorine-containing hydrocarbons, alkanes, olefins, alkynes or aromatic hydrocarbons, e.g., ethane, propane, acetylene, benzene. Output of carbon nanofibres is equal to or more than 600 g per 1 g metal. ^ EFFECT: high efficiency of the method. ^ 5 cl, 2 dwg, 9 ex |
