The present invention relates to the production of high purity solar grade silicon from common rice hulls. A unique process for material purification and reduction includes leaching the rice hulls in acid followed by treatment with high purity water, coking the acid-cleaned hulls in a non-oxidizing ambient, compensating the carbon or silica content of the coked hulls to obtain a desired carbon to silica ratio and reducing the silica to produce high purity silicon.

Method for producing solar cell-grade silicon from rice hulls

The present invention is directed to an electric current-producing cell which contains: (a) an anode having as its anode-active material one or more alkali metals; (b) a cathode having as its cathode-active material one or more polymer compounds having a plurality of carbon monosulfide units; and (c) an electrolyte which is chemically inert with respect to said anode and said cathode and which permits the migration of ions between said anode and said cathode.

Cells having cathodes containing carbon monosulfide polymer

Coal is electrophilically aromatically substituted (i.e., alkylated or acylated) in the presence of an alkylating or acylating agent with or without a catalyst under mild conditions to give a treated coal product. This treated coal product may then be solvent extracted to give an extract and an upgraded coal residue, with this residue being subjected to a gasification process procedure or the treated coal product may be subjected to gasification process procedures without any prior extraction being performed. By means of either technique, a material is prepared for which the rate of gasification and the yield of desired product upon gasification is dramatically increased when compared with nonelectrophilically aromatically substituted material (i.e., raw coal). An improved gasification process is disclosed comprising the steps of electrophilically aromatically substituting coal and subjecting such pretreated coal, either extracted or unextracted to gasification process techniques.
