ABSTRACT OF THE DISCLOSURE A heat transfer-integrated hydrocarbon and heat energy producing system for coal treatment or like carbona- ceous solid fuel reactant for the co-production of hydrocarbons and heat energy, this system including introducing a single phase molten salt solution of the reactant into a first reaction zone, generating active hydrogen by steam dissociation within the zone, contacting the reactant with the active hydrogen within the first zone and under hydrogenating conditions sufficient to hydrogenate the relatively more reactive 50 to 85% by weight portion of the reactant, separat- ing overhead a stream comprising produced hydrocarbons and recovering the hydrocarbons; passing the first reaction zone effluent comprising a molten salt solution of the reactant to a second reaction zone, introducing an oxidizing gas into the solution in the zone under combustion conditions sufficient to substantially completely oxidize the unreacted reactant with the release of heat of combustion into the molten salt, passing combustion gases overhead from the second reaction zone, passing the molten salt second reaction zone effluent after transferring combustion heat therefrom back to the first reaction zone, adding fresh reactant to the effluent and repeating the hydrogenation and combustion cycle.
