A study was made of the influence of ZSM-5 zeolite on the composition and properties of the products of fast pyrolysis of flax shives in the temperature range of 350-750 °C. Zeolite ZSM-5 increased the heat of combustion of gaseous products, as well as the content of methane, ethylene, hydrogen, and carbon dioxide, which is probably associated with the processes of cracking of volatile products passing through a layer of a catalyst heated to high temperatures. The synthesis and study of zeolite catalysts ZSM-5 containing transition metals (Fe, Co, Ti, V, Mn, Zn, Cu, Cr) with a 2% metal concentration in the process of deoxygenation of volatile products of fast pyrolysis of waste biomass of plant origin. According to the activity in the deoxygenation process, the metals studied during the work stage can be arranged in the following descending order: Pd > Pt > Co > Cu > Ni > Fe > Cr > Mn > V > Ti > Zn.The 2%Co-ZSM-5 catalyst showed high activity in the deoxygenation process, since its use led to an increase in the low volumetric calorific value of the fast pyrolysis gas by 1.3-1.5 times, as well as to a decrease in the tars content.
