METHOD OF RECEIVING OF HIGH-OCTANE COMPONENT OF BENZINE, CONTAINING METHYL-TRETALKYL ETHERS Russian patent published in 2009 - IPC C07C41/06 

FIELD: oil and gas production.

SUBSTANCE: invention relates to field of oil processing and petrochemistry, particualrly to methods of receiving of blending fuels, containing methyl-tretaktyl ethers (MTAE) by means of interaction of hydrocarbon flows, containing olefins C₄-C₇ with alcohol ensured by inclusion into the process of pretreatment of raw material of additional stages of removing of mechanical impurities, moisture and dissolved in it admixtures before stage of selective hydrogenation of diene hydrocarbons and removing of moisture after stage of hydro-isomerisation of olefins, separated by implementation of process of selective hydrogenation of diene hydrocarbons and hydro-isomerisation of olefins, release of product by means of etherification, containing methyl-tretaktyl ethers C₅-C₈, which are used in the capacity of blending fuels excluding separation from reacted hydrocarbons and methanols.

EFFECT: increasing operation life of catalysts of stages of selective hydrogenation of diene hydrocarbons, hydro-isomerisation of olefins and etherification, reduction of energy intensity of manufacturing, reduction of corrosive wear of equipment, improvement of performance attributes of motor gasolines, improvement of ecological properties of high-octane component of gasoline.
