TL;DR: In this paper, a new selective alkylation procedure was developed which converted polar hydroxyls into relatively non-polar ethers and esters, and has been successfully tested on a bituminous and sub-bituminous coal.

TL;DR: In this article, the average chemical structure of n-heptane asphaltenes present in a vacuum resid feed is related to the morphology of the coke that is produced in a delayed coker (shot coke vs sponge coke).
Abstract: The average chemical structure of asphaltenes present in a vacuum resid feed is related to the morphology of the coke that is produced in a delayed coker (shot coke vs sponge coke). A combination of solid-state 13C NMR, X-ray photoelectron spectroscopy (XPS), and elemental abundance was used to characterize the average chemical structure of several n-heptane asphaltenes from shot-coke- and sponge-coke-producing vacuum resid feeds. The chemical structural properties of the asphaltenes are discussed in relation to the coke morphology produced from the parent resid. The average asphaltene aromatic carbon per cluster size is between 14 and 22 carbon atoms, which corresponds to three-to-five-ring average clusters. When the ratio of aromatic carbon to unreactive (i.e., heterocyclic aromatic) nitrogen and sulfur in asphaltenes is <16, the feed tendency is to produce shot coke. Representative chemical structural models of asphaltenes reveal significant differences (1.5 cal/cm3)1/2 in the calculated solubility par...
