ABSTRACT:
A kerogen-agglomerated oil shale is contacted with an acid-containing solution prior to economically upgrade the oil shale prior to retorting. The kerogen is agglomerated by contacting the oil shale with a two phase mixture of an organic liquid and water to form kerogen-rich agglomerates and mineral-rich particles. Acids suitable for use in this invention include any acid capable of forming a soluble metallic salt, preferably sulfurous acid.
