In this work, the results of the investigation of catalytic activity of iron subgroup metal-containing catalysts in the process of pyrolysis of flax shive are presented. The influence of iron subgroup metals oxides, nitrates, and chlorides on flax shive pyrolysis process the samples with 10 % content of mineral compounds was investigated by thermogravimetric analysis. The natural and synthetic zeolite materials (ZSM-5) were used as metal-containing catalysts in the pyrolysis process of flax shive. The resulting catalyst – ZSM-Bentonite clay + 2 % (wt.) Co had the highest catalytic activity, which was to accelerate the process of pyrolysis and to increase the content of gaseous hydrocarbons C1-C4 at the composition of the pyrolysis gas. In the presence of ZSM-bentonite clay + 2 % (wt.) Co the concentration of hydrocarbons C1-C4 was increased compared to the non-catalytic pyrolysis process.
