The Application of Data Enhancement Techniques to the Study of Hydrocarbon Oxidation Processes

Oxidative and thermal degradation of hydrocarbon oils are complex processes. While the fundamental chain reaction mechanisms are known, the actual chemistry of a formulation involving several additives still remains a gray area. An understanding of some of the additive interactions and their degradation pathways will ultimately lead to a more scientific approach to formulation optimization for a given application. Current methodology involves laboratory oxidation tests as a screening mechanism before the more expensive mechanical tests are used for the final lubricant evaluation. This is particularly the case for automotive and gas turbine lubricants. The chemistry linking the laboratory test and the mechanical tests for a given oil formulation are rarely considered.
