METHOD AND INSTALLATION FOR PRODUCING HIGH-OCTANE SYNTHETIC GASOLINE FRACTION FROM HYDROCARBON-CONTAINING GAS Russian patent published in 2017 - IPC C10G2/00 

FIELD: chemistry.

SUBSTANCE: method includes supplying hydrocarbon gas to the installation, dividing it into two flows-technological and power, directing the energy flow to combustion, heating the nodes of heat-using equipment with flue gases, purifying the hydrocarbon gas flow from sulfur compounds, obtaining synthesis gas by high-temperature reforming of hydrocarbon gas with water vapour and carbon dioxide, obtaining liquid hydrocarbons and water, followed by separation into high-octane synthetic gasoline fraction and water. Carbon dioxide for synthesis gas production is recovered from the combustion products of the hydrocarbon gas energy flow by absorption and desorption method, vapour-carbon-dioxide conversion is conducted on a nickel-containing catalyst, liquid hydrocarbons are obtained from synthesis gas in reactors containing a bifunctional catalyst.

EFFECT: production of high-octane synthetic gasoline fraction, satisfying high ecological characteristics, with high selectivity.
