    摘要: Finely divided, small particle (0.1 micron or less) small crystallite (about 50 A.times.100 A or less) chalcogenides of manganese, rhenium and technetium are described. These compositions are prepared by mixing the absence of an aqueous solvent, a manganese, rhenium or technetium salt with a source of chalcogenide yielding a precipitate. The manganese, rhenium or technetium salt and the source of chalcogen can be mixed either neat or in the presence of a nonaqueous aprotic solvent. The precipitate which results before removal of the anion salt is a finely divided product. In the case of rhenium dichalcogenide the product possesses a layered structure. The anion salt may be removed by any technique common to the art, pumping under vacuum being one such technique, washing with a suitable solvent being another.A method is described for the preparation of di- and poly-chalcogenides of the formula MX.sub.y wherein M is a metal selected from the group consisting of mangangese, rhenium and technetium, X is a chalcogen selected from the group consisting of sulfur, selenium, tellurium and mixtures thereof, and y is a number ranging from about 1.5 to about 4, preferably about 2, comprising the low temperature, nonaqueous precipitation of said MX.sub.y compounds from mixtures of the salts of said manganese, rhenium and technetium. Said precipitation occurs in the absence of aqueous solvents. The process of the instant invention permits the preparation of materials uncontaminated by water, oxygen or hydrolysis products.

    摘要: A method is described for the preparation of chalcogenides of ruthenium, rhodium, osmium and iridium transition metals of the Periodic Table of the Elements which comprises mixing in the absence of an aqueous solvent a Group VIII transition metal salt with a source of chalcogenide, said chalcogenide being selected from the group consisting of sulfur, selenium, tellurium and mixtures thereof, yielding a precipitate of the formula MX.sub.y wherein M is selected from the group consisting of ruthenium, rhodium, osmium and iridium, X is sulfur, selenium, tellurium and mixtures thereof and y is a number ranging from about 0.1 to about 3, preferably 0.1 to about 2.5. By the practice of the nonaqueous synthesis technique, Group VIII chalcogenides are prepared which are finely divided, have a high surface area, small particle size and small crystallite size which are also free of excess sulfur, water and/or hydrolysis products. This technique also permits the preparation of a heretofore unobtainable composition, layered stoichiometric osmium disulfide. The precipitates which result as a consequence of the instant process may be cleansed of any anion salt coproduct by any technique common to the art, pumping under vacuum being one such technique, washing with a suitable solvent being another.Compounds of the formula MX.sub.y wherein M, X and y are as defined above, prepared by the low temperature, nonaqueous precipitation technique herein disclosed are superior sulfur-tolerant catalysts in catalytic processes, for example, hydrodesulfurization, hydrodenitrogenation, hydroconversion, hydrogenation.

    摘要: A zero-discharge landfill process is disclosed herein. The process described in the present invention recycles the exhaust gases from a combustion engine which reheats the landfill and provides moisture. Additionally, the CO2 from the exhaust gases releases additional methane. Methane production in landfills can thus be enhanced by the method of the present invention. Furthermore, a portion of the exhaust gas can be used to cultivate algae in a cultivation tank. The cultivation of the algal species is enhanced in the presence of water, CO2, CO, and the elevated temperatures. Optionally, a first portion of the cultivated algae can be passed through the landfill to increase methane production in the landfill and a second portion of the cultivated algae can be transferred to a biodiesel production tank, for the conversion of the one or more algal oils and lipids to a biodiesel or a biofuel by a transesterification reaction.
