The effective methods of decarboxylation of oil acids isolated from crude oil in the presence of natural and synthetic alumosilicate catalysts have been considered and studied. The results of investigation and priorities of this method have been showed. The composition of natural alumosilicate involves in % mas.: 55.0–65.0 SiO2, 25.0–35.0 Al2O3, 1.1–1.3 CaO, 0.2–0.3 K2O, 0.3–0.4 MgO. The composition of synthetic alumosilicate ²zeocar-2², consists of in % mas.: 83–85 SiO2, 9–11 Al2O3, 0.3 Na2O, index of activity – 49, index of stability – 50, the average diameter of particles – 3–4 mm. The results of investigations and the advantages of method have been showed. It has been established that decarboxylation of petroleum acids in the presence of aprotonic catalysts in the temperature range of 400 to 4500C and volumetric rate in 0.7–1.0 h-1 permit to receive the highly power consuming components for reactive fuels.
