“…Only naphthene aromatic compounds are able to directly transfer hydrogen by reduction of the corresponding compounds in a hydrothermal process. The hydrogen from formic acid can be produced by dehydration with the formation of CO and H 2 O. The ability of naphthene aromatic compounds to donate an even number hydrogen atoms is used in hydrogen-solvent cracking processes . A significant number of studies investigating the in situ upgrading of heavy oils reported application of tetralin as a hydrogen donor. , Aquathermolysis in the presence of tetralin provides a higher viscosity and density reduction degree.…”

“…Only a couple of studies have focused on visbreaking in the presence of additives. [24][25] Recently, a small addition of water has showed reduced coke formation during visbreaking. 26 This work focuses on the upgrading of bio-oils obtained from rapeseed meal (biodiesel production residue) and wheat spent grains (bioethanol residue) into high quality bio-crudes using vis-breaking.…”
