METHOD FOR SYNTHESIS OF HYDROCARBON COMPONENTS OF GASOLINE Russian patent published in 2012 - IPC C10G3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the method for synthesis of hydrocarbon components of gasoline, involving catalytic conversion, at the gasoline synthesis step, of oxygenate-containing material obtained via catalytic conversion of synthetic gas fed into one or more oxygenate synthesis steps; the oxygenate-containing material contains methanol and/or dimethyl ether and a mixture which contains, in terms of the total oxygenated composition, 0.05-1 wt % of one or more oxygenates selected from a group which includes propanol, butanol, pentanol, hexanol, dimethyl ether and ethers of higher alcohols C₃₊ and/or oxygenate equivalents thereof, into hydrocarbon components of gasoline, and one or more oxygenate-containing streams are simultaneously fed into one of the oxygenate synthesis steps, said streams containing methanol, higher alcohols and/or ethers thereof and additionally, if necessary, containing oxygenates selected from a group which includes aldehydes and ketones, carboxylic acids and alkyl esters thereof. The invention also relates to another method for synthesis of hydrocarbon components of gasoline.

EFFECT: conversion of oxygenates into the desired hydrocarbon products.
