The production method of the present invention can reuse a non-impregnated catalyzed sol, which has been typically discarded, by recovering the catalyzed sol, which is not impregnated in impregnating of a catalyzed sol into a blanket base, to stop gelating the catalyzed sol, and then using this in subsequently preparing a catalyzed sol.

A process for upgrading a hydrocarbon-based composition that includes combining a supercritical water stream with a pressurized, heated hydrocarbon-based composition in a mixing device to create a combined feed stream. The combined feed stream is introduced into a supercritical upgrading reactor to at least partially convert the combined feed stream to an upgraded product. The process includes separating the upgraded product to produce a light fraction and a heavy fraction, and separating the light fraction in the gas/oil/water separator to produce a gas fraction, a liquid oil fraction, and a first water fraction; combining the heavy fraction with at least a portion of one of the liquid oil fraction or the first water fraction to form a diluted heavy fraction; and passing the diluted heavy fraction from the flash drum to a demulsifier mixer to form a demulsified heavy fraction.
