Abstract
The combination of complexity, diversity, and aggregation of asphaltenes has enormous implications for upgrading reactions and phase behavior. Modern instrumental methods were used to quantitatively characterize the pendant groups and building blocks that comprise the residue components. Analyses of the constituent building blocks yielded quantitative results. Families of components representing key structural features of residue molecules were synthesized. The reactions of these molecules under cracking conditions were studied and the molecular basis for coke formation was defined. The importance of addition or retrograde reactions when cracking occurs in the liquid phase was highlighted. A synthesis of these two approaches was put forward, including defining the molecular features that control residue behavior, main pathways for coke formation, and implications for advanced residue processing in the future. Controlling the unwanted liquid phase reactions is key to improving yields of distillate products from the bottom of the barrel. This is an abstract of a paper presented at the 2011 AIChE Spring Meeting & 7th Global Congress on Process Safety (Chicago, IL 3/13-17/2011).
