ABSTRACT:
Tar sands are solvent extracted to form an oil-containing extract and a sandy residue. The solvent can be distilled from the oil and recycled. Residual solvent vapors can be adsorbed on an adsorbent bed. The sandy residue can be flash pyrolyzed to provide a combustible synthesis gas and/or combusted to provide process heat. Where the adsorber bed is formed from activated charcoal, a pair of beds on swing adsorption/regeneration cycles can be regenerated with steam and provide for continuous adsorption solvent vapors.
