1. A process for converting hydrocarboneous feed material into liquid and gaseous hydrocarbons suitable for further processing via pyrolysis, said pyrolysis conducted in the presence of zeolite type catalyst in an oxygen-free environment, comprising
mixing the feed material previously shredded to less than 50 times 50 mm with zeolite type catalyst in an amount of 3-5% relative to its total weight in the absence of ambient air, subjecting the mixture to pyrolysis in three steps at a temperature from 450 to 650 degree C. for a residence time of between 10 minutes and 30 minutes while the pressure is maintained between −300 Pa and 300 Pa, continuously moving the feed material mixed with catalyst during the pyrolysis whereby different phases of the thermal destruction occur successively but separately in terms of space and time in three reaction chambers, removing the gaseous products evolved during the pyrolysis, condensing at least a portion of the evolved gases, purifying the condensed gases, storing the purified liquid fractions with different characteristics separately, using at least portion of the purified liquid as fuel for producing electricity, transferring the heat evolved during the electricity production, recycling the sludge subsided during the storage as feed material, cooling the non-condensed gases, burning the non-condensed gases to provide heat for the pyrolysis, removing the solid residue left over from the pyrolysis. |
