Abstract (en)
A solvent extract obtained from a conventional hydrocarbon solvent extraction process, for example one employing furfural as the extraction solvent, is cooled and separated by decantation to provide a pseudo-raffinate containing most of the non-aromatics and a pseudo-extract having a hydro-aromatic content of Halpha hydrogen of at least 20 percent of the total hydrogen content. The pseudo-extract is ideally suited as a hydrogen-donor for a variety of refinery operations such as visbreaking.
