Abstract: A process is described using novel thallium-promoted iron catalysts in CO hydrogenation with steam. Mixtures of CO and steam are converted to liquid C.sub.6 -C.sub.13 hydrocarbons containing substantial amounts of C.sub.6 -C.sub.13 aromatics.

Abstract: CO hydrogenation process is described utilizing novel thallium-promoted iron catalysts. Mixtures of CO/H.sub.2 are selectively converted to liquid C.sub.6 -C.sub.11 hydrocarbons containing C.sub.6 -C.sub.11 aromatics, alpha olefins and very small amounts of C.sub.23 + hydrocarbon waxes.

Abstract: CO hydrogenation process for producing alcohols is described utilizing novel thallium-promoted iron catalysts. Mixtures of CO/H.sub.2 are selectively converted to liquid C.sub.6 -C.sub.12 hydrocarbons containing C.sub.6 -C.sub.12 alcohols with attendant low methane and low CO.sub.2 make.

Abstract: Novel thallium promoted iron catalysts are described as being useful in CO hydrogenation processes utilizing CO/H.sub.2 mixtures for selectively producing C.sub.6 -C.sub.11 liquid hydrocarbons, containing C.sub.6 -C.sub.11 aromatic hydrocarbons and only very small amounts of C.sub.23 + hydrocarbon waxes.

Abstract: A process for synthesizing light paraffinic hydrocarbons, preferably C.sub.1 -C.sub.3 in carbon number, from CO and steam is described utilizing novel molybdenum oxycarbonitride catalyst.

Abstract: 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.

Abstract: 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.

Abstract: 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.
