In this work the influence of natural and synthetic aluminosilicates, metal chlorides of iron subgroup on the peat low-temperature pyrolysis and co-pyrolysis of peat with oil-slime and polymeric waste was studied in variety of conditions (t = 350-650°C, catalyst loading: from 1 up to 30 % (wt.)). The use of bentonite clay (30 % (wt.)) at 460°C as a catalyst in peat pyrolysis resulted in increase of weight of gaseous and liquid products from 23 up to 30 % (wt.) and from 32 up to 45 % (wt.), respectively. Co-pyrolysis of peat and oil-slime in the presence of bentonite clay resulted in increase of gaseous product weight from 18 up to 26 % (wt.) and liquid fraction yield - from 45 up to 55 % (wt.) in comparison with precalculated value. The use of metal chlorides of iron subgroup (2 % (wt.) concentration) at 500°C in the co-pyrolysis of peat and polymeric waste led to optimal conversion of substrate in desired products, 15 % increase of total weight of gaseous and liquid products formed during the pyrolysis process and simultaneous decrease of char formation.
