Theory of Radiation-Induced Cracking Reactions in Hydrocarbons
Published in Yuriy Zaikin, Raissa Zaikina, Petroleum Radiation Processing, 2013
Among the products of the RTC of n-butane, a series of octane products was found, such as 3,4 -dimethylhexane (3,4DiMHx), 3-methylheptane (3-MHp), and n-octane (n-Oct). The temperature dependence of these octane yields are shown in Figure 2.19. The other octanes were probably formed by an ionic process, since their yields were suppressed by the addition of ammonia.

Wang et al. (2013) found no substantial differences between ignition delays for 3-methylheptane, 2-methylheptane and n-octane at high temperatures, which was associated with the similarity of intermediates formed during the initiation phase. However, at NTC and low temperatures, ignition delay values were substantially different and according to their RONs (37, 22, and 19, respectively). Sarathy et al. (2011a) explained this behavior by the action of the methyl on the isomerization rate of O2QOOH• that lead to chain branching. The difference in the position of the methyl group establishes an imbalance between two possible reaction paths: chain branching and cyclic ether formation. Tanaka et al. (2003) highlighted the relation between the formation of 6-member low strain C-C-C-O-O-H rings (which are characteristic of two-stage ignition) and the structure -CH2-CH2-CH2-, with relatively short ignition delays time and burn rates.
Comparison of biodegradation of lubricant wastes by Scenedesmus vacuolatus vs a microalgal consortium

After week 3, eleven chemical compounds were present compared to the control. Tetradecane was found less abundant while p-xylene was the most abundant in the oil. Reduction and increase in hydrocarbons concentration were observed. New compounds such as 2-isopropyl-5-methyl-1-heptanol, 1-heptanol,2,4-diethyl, 11-methyldodecanol, tetradecane, 3-ethyl-3-methylheptane and heptane,2,5-dimethyl were formed. 3-ethyl-3-methylheptane was found to be isomer of decane and heptane,2,5-dimethyl isomer of nonane.
