METHOD FOR OBTAINING DIESEL FROM VEGETABLE OR ANIMAL OILS BY MEANS OF HYDROPROCESSING WITH REDUCED RESIDENCE TIMES AND RESULTING PRODUCTS

摘要

The invention relates to a method for obtaining diesel fuel from vegetable or animal oils through the addition of hydrogen in the presence of catalysts under suitable temperature and pressure conditions. The method is different from other similar methods in that it involves the use of space velocities of between 5.1 h-1 and 9 h-1, thereby enabling a reduction in the size of the reactor and in hydrogen consumption, as well as lowering construction and operating costs. The invention also relates to the products obtained using said method, which have demonstrated that in additions, even below 10%, they improve the performance of diesel engines, thereby lowering fuel consumption.
