Selective production of light synthetic gasoline

The present disclosure relates to a production plant and a method for production of a synthetized gasoline product from a synthetic hydrocarbon mixture produced from a mixture of reactive oxygenates comprising the steps ofa. separating the synthetic hydrocarbon mixture in at least a light hydrocarbon frac-tion, and a higher boiling hydrocarbon fraction, wherein the higher boiling fraction comprises at least 70% of the molecules comprising 10 or more carbon atoms pre-sent in the hydrocarbon mixture and less than 20% of the molecules comprising ex-actly 9 carbon atoms present in the synthetic hydrocarbon mixture,b. directing at least an amount of said higher boiling hydrocarbon fraction as a hy-drocracking feedstock to contact a material catalytically active in hydrocracking un-der effective hydrocracking conditions providing a hydrocracked hydrocarbon stream,wherein at least an amount of said hydrocracked hydrocarbon stream, optionally after further hydroprocessing, is combined with at least an amount of said light hydrocarbon fraction, to provide said synthetized gasoline product having a T90 according to ASTM D86 being below T90 according to ASTM D86 of said synthetic hydrocarbon mixture, such as 10°C or 20°C below, with the associated benefit of such a process reducing the upper boiling point of the synthetized gasoline product, by hydrocracking C10 and C11 hydrocarbons, especially two-ring aromatics, while minimizing the yield loss of gasoline product.
