ABSTRACT:
Bituminous sands are intimately contacted with an aqueous medium containing a catalytically effective amount of a novel catalyst to separate the bitumin at temperatures below the decomposition point of valuable hydrocarbons contained therein. Usually the temperatures of separation are not higher than 100.degree.C and preferably are about 40.degree.-90.degree.C. The catalyst used in practicing the present invention may be prepared by steps including admixing a water soluble alkali metal silicate with an aqueous medium containing carefully controlled amounts of dissolved water soluble substances which are sources of calcium ion and magnesium ion, reacting the same to produce an aqueous colloidal suspension of the reaction product, admixing a micelle-forming surfactant with the aqueous medium, and agitating the aqueous medium containing the colloidal particles and surfactant to form catalyst containing micelles.
