Thermographic Investigations of Deasphalted Oil in the Presence of Zinc, Nickel and Iron 2-Ethylhexanoates

The results of thermographic investigations of the deasphalted oil obtained by deasphalting West Siberian oil tar with butane with the addition of zinc, nickel, and ferrous iron 2-ethylhexanoates and also without additives are presented. The effect of the metal-containing additives on the weight loss process and the change in the magnitude of heat fluxes during thermal exposure was established. The effect on the weight loss of samples of deasphalted oil containing ferrous salts with increase of temperature differs significantly from the effect of additives such as zinc and nickel salts.
