METHOD OF PURIFYING OF SECONDARY GASOLINE FROM SULPHUR COMPOUNDS AND UNSATURATED HYDROCARBONS WITH LIQUID CATALYST COMPLEX Russian patent published in 2016 - IPC C10G29/06 C10G27/12 

FIELD: fuel.

SUBSTANCE: present invention relates to a method of purifying of secondary gasoline from sulphur compounds and unsaturated hydrocarbons. Method involves in treatment of initial stock with 25-30 % aqueous solution of hydrogen peroxide, taken in amount of 0.1-0.3 % wt to stock, at the temperature of 25-56 °C at atmospheric pressure in the presence of 0.05-0.15 % wt catalyst to raw material. At that as catalyst used is acetone, and as the cleaning reagent - liquid catalytic complex based on zinc chloride or aluminium chloride with the following structure: zinc chloride or aluminium chloride - 60-70 % wt, light paraffin hydrocarbons C₅-C₆ - 20-30 % wt, propionic acid - 10-20 % wt at the ratio of complex to material by weight 1:3.

EFFECT: proposed method allows to obtain products of good quality.
