FIELD: petroleum chemistry, chemical technology.
SUBSTANCE: hydrocarbons with high octane number are prepared from mixtures consisting of n-butane and isobutene, such as butanes from gaseous deposits. Method involves section for skeletal isomerization, section for dehydrogenation of paraffins, section for selective hydrogenation of butadiene and two sections for conversion of olefins. In these sections isobutene is converted selectively firstly by dimerization and/or esterification and then linear butenes are converted by alkylation. Then products from these two sections are combined to obtain product possessing with excellent properties for automobile engine (octane number, volatility and distillation curve).
EFFECT: improved preparing method of hydrocarbons.
