FIELD: petroleum chemistry.
SUBSTANCE: petroleum raw in the range of gasoline boiling point containing sulfur compound and hydrogen is contacted into reactor with the immobile hydrodesulfirization catalyst layer under pressure less 300 pounds/square inch and temperature from 300 to 700 F. Temperature and pressure into reactor are regulated for maintenance the reaction flow at its boiling temperature and lower of the condensation point that results to evaporation of part of all the reaction mixture. By the second variant the presence of unsaturated compound in the raw is possible. Method provides enhancing degree in sulfur removal from the raw.
EFFECT: improved treatment method.
