Abstract
(EN)

The subject of the invention is the method of obtaining liquid fuels from polyolefine wastes. According to the method, properly disintegrated polyolefines in an amount of 100 parts y weight are heated in the temperatures between 300 DEG C to 450 DEG C till the moment of a decay of volatile product forming, in the presence of heavy metals silicates as catalysts, added in amounts of 1-30 parts by weight. As catalyst, the silicates of iron Fe<3+>, cobalt Co<2+>, nickel Ni<2+>, manganium Mn<2+>, chromium Cr<3+>, copper Cu<2+>, zinc Zn<2+>, cadmium Cd<2+> and/or their mixtures are used. The catalyst is applied in an amorphic form in an amount from 5 to 10 % by weight, calculated on the mass of the raw material. The catalyst is recycled and used multiply. A process is run in a continous way.
