METHOD OF CRUDE OIL DISTILLED FRACTIONS WITHDRAWAL INCREASE Russian patent published in 2009 - IPC C10G11/04 

FIELD: oil-and-gas production.

SUBSTANCE: invention related to oil-and-gas production, particularly to crude oil refinery during low temperature initiated trekking, can be used for distillated motor fuel production increase. Method of gasoline and crude oil distillated fraction withdrawal increase executes by adding catalyst followed by thermal cracking, ashes magnetic fractions of micro spheres from heat and power station used as the catalyst, with a content 40.0-95.0% wt, iron oxide (III) with micro sphere diametres 0.01-0.60 mm, tempered at 600-800°C, process itself executed at temperature 400-500°C.

EFFECT: distillated fraction withdrawal increase (temperature up to 350°C) till 83,0% wt, gasoline fractions withdrawal up to 65,0% (at temperature up to 200°C).
