FIELD: chemistry.SUBSTANCE: one of versions includes stages, at which hydrocarbon supplied initial raw material is separated into first fraction of carbon-containing compounds which contain not more than 5 carbon atoms, and second fraction of compounds, which have lower pressure of steam in comparison with pressure of steam in first fraction; dienes and/or acetylenes from first phase are selectively hydrated with formation of respective monoolefins; paraffins from first fraction are converted with formation of respective monoolefins in conversion flow; and contact cooling of subjected to transformation monoolefins from conversion flow with application of liquid hydrocarbon flow, which contains admixtures, with admixtures having lower pressure of steam in comparison with pressure of steams of compounds from first fraction; where dienes and/or acetylenes from first fraction are subjected to selective hydration before transformation of paraffins from first fraction with formation of monoolefins and after extraction of first fraction from supplied initial hydrocarbon raw material.EFFECT: application of claimed invention makes it possible to render minimal influence on selective hydration catalysts.10 cl, 1 dwg |
