Definitions for "Asphaltenes"
Insoluble, semi-solid, or solid particles which are combustible and are highly aromatic. Asphaltenes contain a high carbon to hydrogen ratio and entrap water, fuel ashes and other impurities.
A class of organic materials defined by their insolubility in pentane or heptane. Asphaltenes are generally polar molecules, rich in S, N, O, and organically bound Ni and V. The vast majority of asphaltenes distill at temperatures above about 1000° F (540° C). They are an important component of asphalt.
one of the principal components of asphalt, the black or brown solid material precipitated from asphalt with normal pentane. It is an arbitrary fraction defined by the method of analysis
