Claim 8:
9. The process as in claim 1, wherein:
the reformate is processed and separated in an aromatic recovery complex by
separating the reformate into a first portion containing C6 aromatic hydrocarbons and a second portion containing C7-C8+ aromatic hydrocarbons,
separating the first portion of the reformate into benzene and non-aromatics,
separating the second portion of the reformate into toluene and a C8+ aromatic hydrocarbon fraction,
separating the C8+ aromatic hydrocarbon fraction into a C8 aromatic hydrocarbon fraction and a C9+ aromatic hydrocarbon fraction,
separating the C8 aromatic hydrocarbon fraction into para-xylene, and other C8 aromatic hydrocarbons, and
isomerizing the other C8 aromatic hydrocarbons to produce additional para-xylenes and C8+ hydrocarbons that are recycled to separation of the C8+ aromatic hydrocarbon fraction derived from the second portion of the reformate;

all or a portion of the toluene is the portion of the reformate that is reacted to produce hydrogen carrier; and
benzene and para-xylene are recovered as chemical products.
