Methods of processing, transporting, or both, of hydrogen

A method for processing hydrogen, the method comprising:

• passing a heavy naphtha stream, a C9+ aromatic compounds containing stream comprising at least 60 wt. % C9+ aromatic compounds, and an input hydrogen-containing stream to a hydrotreater to form a hydrotreated effluent stream, wherein:
• the heavy naphtha stream has an initial boiling point of from 80° C. to 100° C. and a final boiling point of from 180° C. to 220° C.;
• and
• the hydrotreated effluent stream comprises hydrotreated naphtha and one or more saturated cyclic C9+ compounds;
• passing the hydrotreated effluent stream to a separator to form a naphthenic stream and a separation unit effluent stream, wherein:
• the naphthenic stream comprises at least 50 wt. % saturated cyclic C9+ compounds;
• and
• the separation unit effluent stream comprises at least 50 wt. % of hydrotreated naphtha;
• passing the separation unit effluent stream to a catalytic reformer to form a reformate stream;
• passing the reformate stream to an aromatics separation unit to form an aromatics containing stream and a non-aromatics containing stream, wherein the aromatics containing stream comprises at least 50 wt. % of aromatic compounds and the non-aromatics containing stream comprises at least 50 wt. % of non-aromatic compounds;
• passing the aromatics containing stream to an aromatics complex to form the C9+ aromatic compounds containing stream;
• and
• recycling the C9+ aromatic compounds containing stream to the hydrotreater.
