Abstract
A bitumen stream is upgraded by heating to near-critical or super-critical conditions in the stream. The bitumen stream may be from a water-based extraction process, an in situ bitumen recovery process, or a solvent-based bitumen extraction process. To achieve an appropriate feed stream composition, water and/or clay may be added. The clay offers a catalytic effect. To achieve an appropriate feed stream composition, water may alternatively be removed.
