Lester, G R

A method is described for producing the hydrogen required in liquefying coal to provide aromatic products such as benzene and naphthalene. The method includes the steps of contacting hydrogen produced in the process with coal in a liquefaction zone and refining the hydrocarbon liquefaction product, which includes polycyclic aromatics, polycyclic hydroaromatics, and alkylaromatics, by contacting the liquefaction product with steam and a steam dealkylation catalyst in order to react the hydrocarbons and steam to provide hydrogen and aromatic products. The aromatic products are recovered from the resulting liquids and the hydrogen thus produced is passed to the coal liquefaction step.
