The effect of n-butyl bromide on thermal transformations of maltenes from heavy oil of the Usinskoye oil field (Komi Republic) was explored. The cracking of maltenes was performed at 450 °С for 2 h in the isothermal mode in the presence of the initiating additive, n-butyl bromide. The data for the mass balance of the process and the composition of liquid cracking products were acquired. Variations in the hydrocarbon composition of the cracking products were investigated. As demonstrated, the addition of n-butyl bromide (0.7 mass % of the mass of raw materials) led to a 1.8 times increase in the yield of distillate fractions boiling up to 360 °С compared to cracking without the additive. As determined, along with the profound destruction of resins, oils were exposed to transformation upon the cracking of maltenes with n-butyl bromide due to dealkylation and dehydration reactions.
