The disclosed process removes or reduces impurities such as asphaltenes, solids (especially solid fines), sulfur, metals, chlorides, water, salts, and acids from bitumen, oil sands, and crude oils with a wide range of gravities. A crude source composition is contacted with one or more zeolite materials to remove asphaltenes, solids, sulfur, NSO, metals, chlorides, water, salts, and/or acids from the composition. The crude source is typically diluted with a hydrocarbon solvent such as naphtha before contacting the zeolite(s). The disclosed processes represent an improvement over prior and presently available processes because the disclosed processes are capable of processing emulsions.

Biogenic silica is produced by combusting a biogenic source material such as rice hulls to give rich hull ash (RHA), and the combusted biogenic silica may be subsequently treated to improve the filtration or adsorption properties thereof e.g. by changing the surface charge, the surface tension, the surface area, the average pore size, the pore size distribution, particle size distribution, and/or the permeability thereof. Such biogenic silica is useful to remove a species, such as an impurity, from a fluid to purify the fluid and/or to recover the species therefrom. RHA may be used to remove species including organic, inorganic or microbial particulates, surfactants, metal ions, non-metallic anions, organic compounds, color bodies, odor-producing species, chlorinated compound, pigment, free fatty acids, phospholipids, peroxides, oil and/or grease different from the non-aqueous fluid, algae, bacteria, and combinations thereof.
