International Classification:

B01J 2906
B01J 2302
B01J 2104

US Classification:

502 64

Abstract:

A composition of matter comprising at least one metal-containing spinel which includes a first metal and a second metal having a valence higher than the valence of the first metal, a minor amount of at least one-third metal component effective to promote the oxidation of sulfur dioxide to sulfur trioxide at sulfur dioxide oxidation conditions, and a minor amount of at least one-fourth metal component effective to promote the reduction of first metal sulfate at first metal sulfate reduction conditions. These compositions are useful, e. g. , in hydrocarbon conversion processes, to reduce sulfur oxide and/or nitrogen oxide atmospheric emissions.

International Classification:

C10L 910
C10B 5700

US Classification:

44 1R

Abstract:

A process for reducing the sulfur content of coal comprising the steps of: (1) contacting coal particles with an aqueous solution of iron complexing agent, and an oxidant to preferentially oxidize at least a portion of the sulfur in the coal; (2) contacting the oxidized sulfur-containing coal with at least one hydrogen donor material capable of transferring hydrogen to the oxidized sulfur-containing coal under conditions such that hydrogen transfer occurs; and (3) recovering coal products of reduced sulfur content.

International Classification:

C10L 910
C10B 5700

US Classification:

44 1SR

Abstract:

A process for reducing the pyritic sulfur content of coal comprising the steps of: (1) contacting an aqueous slurry of water and pyrite-containing coal particles at elevated temperature with oxygen, the contacting of step 1 being such that without step 2 the aqueous slurry would have a pH of less than 5. 5; (2) maintaining the aqueous slurry of step 1 at a pH of from about 5. 5 to 12. 0; and (3) recovering coal particles of reduced pyritic sulfur content.

International Classification:

C10G 1106

US Classification:

208120

Abstract:

In a catalytic cracking process wherein the cracking catalyst is poisoned and contaminated by metal present in the feedstock, an improved process for the removal of such metal poisons as nickel, iron and/or vanadium is employed which comprises contacting a regenerated and sulfided catalyst with an oxygen-containing gas in a defined temperature range of from about 525. degree. F. to about 725. degree. F. and washing at least a portion of the metal poisons from the catalyst. A preferred wash solution is a reductive wash medium comprising a saturated, aqueous solution of SO. sub. 2. The vanadium and nickel metals may be recovered from the resultant used wash solution for possible metallurgical use. The washed catalyst may also be subjected to subsequent oxidative washes such as a hydrogen peroxide wash prior to its return to the catalytic cracking process.
