FIELD: chemistry.
SUBSTANCE: invention refers to a method for oligomerisation of one or more hydrocarbons involving the stages, at which: A) raw material containing one or more C3 and C4-hydrocarbons is supplied into a separation compartment; B) at least a portion of C3-olefins is separated, and a C3-olefin flow is generated; C) the above C3-olefin flow is dried to reduce water content in the C3-olefin flow; D) a recycle flow supplied from a hydrotreating compartment and containing paraffin waxes is added to the above C3-olefin flow to produce a combined C3-olefin flow; E) at least a portion of the combined C3-olefin flow is introduced into a first oligomerisation compartment to produce one or more C9-hydrocarbons; and F) at least a portion of the flow escaping the oligomerisation compartment is supplied back to the separation compartment.
EFFECT: using the present invention provides the more efficient way to produce petrol.
