Appl. No.:

5/797279

Inventors:

Ralph Miller - Pleasantville NY

Assignee:

Ciba-Geigy Corporation - Ardsley NY

International Classification:

C01G 4502

US Classification:

423592

Abstract:

This invention relates to a process for the thermal decomposition of metal nitrates which decompose below a temperature of about 400. degree. C. to form the corresponding metal oxide as well as oxides of nitrogen, said process involving distributing said nitrate over previously formed oxide and conducting said decomposition under "muffle" conditions such that said decomposition occurs in an atmosphere predominantly comprised of the vapors evolved during the thermal decomposition.

Inventors:

Ralph Miller - Pleasantville NY

Assignee:

T-Thermal, Inc. - Conshohocken PA

International Classification:

C01B 1702

US Classification:

423573R

Abstract:

This invention is a regenerable process for converting H. sub. 2 S to S by (1) reacting the H. sub. 2 S with Fe. sub. 2 (SO. sub. 4). sub. 3 to form S, FeSO. sub. 4 and H. sub. 2 SO. sub. 4 ; (2) separating the S; oxidizing the FeSO. sub. 4 and H. sub. 2 SO. sub. 4 with a gas containing oxygen in the presence of NO to form H. sub. 2 O, Fe. sub. 2 (SO. sub. 4). sub. 3 and a gas with a depleted oxygen content, separating the gas from the Fe. sub. 2 (SO. sub. 4). sub. 3 and recycling the Fe. sub. 2 (SO. sub. 4). sub. 3 to the S formation reaction.

Inventors:

Ralph Miller - Pleasantville NY

Assignee:

Ciba-Geigy Corporation - Ardsley NY

International Classification:

C05G 300

US Classification:

71 1

Abstract:

A process for uniformly coating granular fertilizer formulations with one or more chelated metallic micronutrients which comprises the following steps: blending a granular fertilizer formulation in, for instance, a rotary drum mixer; spraying, while the blending continues 1 to 5% by weight of an aqueous solution or slurry containing one or more chelated metallic micronutrients, as for example, Na. sub. 2 Zn EDTA, onto said fertilizer formulation; and adding, before or after said spraying, and while the blending continues 1 to 4% by weight of a finely divided water-absorbent additive, such as, a synthetic calcium silicate or finely divided silica, to the fertilizer formulation. The finished fertilizer formulation then contains 0. 05 to 0. 5% by weight of micronutrient.

US Classification:

423558

Abstract:

The present invention provides a method of using air to reclaim and recycle potentially contaminating NO in a system producing ferric sulfate solution from the oxidation of ferrous sulfate and sulfuric acid in the presence of NO and oxygen. The present invention economically avoids a potentially wasteful and hazardous production of NO containing gas.

Abstract:

This invention is a regenerable process for producing gaseous hydrogen sulfide in concentrated form from sulfur dioxide obtained from a dilute gas source by (1) reacting the SO. sub. 2 with a concentrated solution of Na. sub. 2 SO. sub. 3 to form Na. sub. 2 S. sub. 2 O. sub. 5 in solution and then either: (2) reacting the Na. sub. 2 S. sub. 2 O. sub. 5 with Na. sub. 2 CO. sub. 3 to form solid Na. sub. 2 SO. sub. 3, a concentrated solution of Na. sub. 2 SO. sub. 3 which is recycled to the SO. sub. 2 reaction and concentrated gaseous CO. sub. 3 which is used in a subsequent step, (3) reducing the Na. sub. 2 SO. sub. 3 to Na. sub. 2 S, (4) reacting the Na. sub. 2 S with solid NaHCO. sub. 3 to form gaseous H. sub. 2 S and Na. sub. 2 CO. sub.
