This paper presents the results of hydrotreating straight run gas oil mixed with soybean oil in a proportion of 10%, 15%, 20%. Hydrotreating was performed at temperatures of 360 degrees C and 380 degrees C, 50 bar pressure, hydrogen/feedstock ratio of 800cm(3)/cm(3), space velocity 1,5cm(3)/cm(3)h. The present research has focused on the influence of temperature and of the vegetable oil/gas oil ratio on the yields and the physicochemical properties of the hydrotreating products. By hydrotreating of straight run gas oil with soybean oil mixtures, result an improvement of flashpoint, sulfur content and density. The secondary hydrocracking reactions which occur during the process, determine the pour point and the flashpoint decreases. These characteristics can be corrected by stabilizing the hydrotreated product.
