MOTOR FUEL OBTAINING METHOD Russian patent published in 2010 - IPC C10G63/00 C10G65/00 C10G69/00 C10G69/08 C10G69/14 

FIELD: oil and gas production.

SUBSTANCE: motor fuel obtaining method involves hydraulic cleaning of mixture of distillates of thermal processes with once-run diesel distillate at increased temperature and pressure, division of hydrogenisate by means of rectification into gasoline and diesel distillates, additional hydraulic cleaning and further reforming of isolated gasoline distillate. Method is differed by the fact that as distillates of thermal processes there used is wide gasoline-gasoil fraction boiling out within temperatures of 30-370°C and which is mixed with once-run diesel distillate in ratio of 10:90 wt % to 40:60 wt %. Additional hydraulic cleaning of gasoline distillate separated from hydrogenisate is performed mixed with once-run gasoline distillate in ratio of 15:85 wt % to 25:75 wt %, after that hydraulically cleaned fraction is supplied to be reformed. Diesel distillate separated from hydrogenisate is partially returned to hydrogenising stage in quantity of 5-20 wt % to initial raw material, and the remaining part is produced as commercial diesel fuel. Hydraulic cleaning is performed at temperature of 330-400°C, pressure of 3-7 MPa in presence of alumino-nickel-molybdenum or alumino-cobalt-molybdenum calalytic agent. In addition, to hydraulic cleaning raw material there can be added 3-30 wt % of light gas oil of catalytic cracking boiling out within temperatures of 160-360°C.

EFFECT: method allows obtaining motor fuels corresponding to requirements of modern standards when enlarging raw material base owing to wider mixed fraction of gasoline and diesel distillates of secondary processes involved in hydrogenising process.
