The goal of this research is the development of the method of oil-slime recycling. 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 a 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 the increase in weight of gaseous and liquid products from 23 up to 30 % wt. and from 32 up to 45 % wt. Co-pyrolysis of peat and oil-slime in the presence of bentonite clay resulted in the increase in 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 °? 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.
