摘要：In this manuscript, the effects of tetrahydronaphthalene (THN)/dihydroanthracene (DHA) mixed with nonhydrogen donor components(n-HDs) as hydrogen donor solvent (HDS) on products distribution and hydrogen consumption during asphaltene (AS) hydrogenation process were investigated. Besides, the interaction mechanism between hydrogen donor (HDs)/non-hydrogen donor (n-HDs) components on hydrogen donating ability was comparatively studied. The results showed that oil-water yields in mixed solvents were 1.89-23.54% and 1.66-24.10% lower than those in THN (48.20%) and DHA (34.42%). The oil-water yields in THN mixtures were higher than those in DHA mixtures, while gas yields in DHA mixtures were higher than those in THN mixtures, which suggested that active hydrogen from DHA mixtures was prone to combine with free radicals to generate gaseous products. Besides, oil-water yields in fluorene (FN), acenaphthene (ACE) and hexadecane (HA) mixtures were higher than those in naphthalene (Nap), anthracene (AN), phenanthrene (PN) and pyrene (PY) mixtures, while the change of coke yields was opposite. Except for hexadecane (HA) mixtures, total hydrogen consumption and hydrogen consumption from H2(HG) in THN mixtures were significantly lower than those in DHA mixtures, which was because that in DHA mixtures, n-HDs were susceptible to be hydrogenated to form hydrogenated aromatics, meanwhile, DHA was also further converted to tetrahydro-anthracene (THA) and octahydroanthracene (OHA). In DHA/HA mixtures, active hydrogen supplied by DHA increased from 1.07 wt% in pure DHA to 1.34 wt%, while HG decreased from 7.96 wt% in pure DHA to 6.58 wt%, indicating that HA was easy to compete for active hydrogen supplied by DHA.
