Appl. No.:

4/769791

Inventors:

Maurice E. Brooks - Great Neck NY

Harvey D. Schindler - New York NY
Morgan C. Sze - Upper Montclair NJ

Assignee:

The Lummus Company - Bloomfield NJ

International Classification:

C07C 6700

US Classification:

260488H

Abstract:

Process for coupling an alkane to either an alkane, alkene, aliphatic carboxylic acid, or aromatic hydrocarbon by effecting contacting thereof and a melt containing a multivalent metal halide in both its higher and lower valence state. In accordance with a preferred embodiment, the contacting is effected in the presence of an oxygen containing gas or the melt is previously contacted with an oxygen containing gas to produce the corresponding oxyhalide of the metal, whereby the reaction may be effected on a continuous basis.

US Classification:

260656R

Abstract:

1,2-Dichlorethane is dehydrochlorinated by direct contact with a molten salt including the higher and lower valent forms of a multivalent metal chloride and generally also the oxychloride of the metal with ethane being present to increase selectivity to vinyl chloride.

US Classification:

208251H

Abstract:

A metal containing hydrocarbon feedstock, such as a heavy residue, is contacted with hydrogen and a material characterized by low porosity, less than 0. 3 cc/gram; low surface area, less than 5 m. sup. 2 /g; high average pore diameter, greater than 1,000 Angstroms; and a high distribution of large pores, at least 40%, and preferably 50 to 80% of pores greater than 10,000 Angstroms. A preferred material is coke.

International Classification:

B01D 3700

US Classification:

210770

Abstract:

A process for disposing of sanitary sewage sludge by producing a pumpable slurry of sewage sludge with or without solid carbonaceous fuel and burning said slurry as fuel in a partial oxidation gas generator, furnace, or boiler. The aqueous slurry of sewage sludge is concentrated by removing water by means of a conventional belt filter press, centrifuge, or hydroclone. The dewatered slurry of sewage sludge is heated by direct contact with steam while air and organic vapors are simultaneously removed, to reduce the pressure in the system; hydrothermally treated in two steps with indirect and direct heat exchange with steam; dewatered by flash evaporation and centrifuging; and burned with or without admixture with solid carbonaceous fuel in a partial oxidation gasifier, furnace, boiler, or incinerator to produce synthesis gas or a hot raw effluent gas stream. In a preferred embodiment, the effluent gas stream is cleaned and purified and non-contaminating ash and slag are separated. By this process, noxious sewage sludge may be disposed of without contaminating the environment.

International Classification:

B01J 2104
B01J 2388

US Classification:

502314

Abstract:

A catalyst for hydrotreating of heavy feedstocks comprised of nickel and molybdenum, supported on alumina having a defined pore size distribution which has been calcined at a temperature of from 1150. degree. F. -1300. degree. F. Calcining of such catalyst at such temperatures is required in order to provide for effective use thereof as a hydrotreating catalyst for higher boiling feedstocks.

Abstract:

Process for coupling an alkane to either an alkane, alkene, aliphatic carboxylic acid, or aromatic hydrocarbon by effecting contacting thereof and a melt containing a multivalent metal halide in both its higher and lower valance state. In accordance with a preferred embodiment, the contacting is effected in the presence of an oxygen containing gas or the melt is previously contacted with an oxygen containing gas to produce the corresponding oxyhalide of the metal, whereby the reaction may be effected on a continuous basis.

Assignee:

The Lummus Company - Bloomfield NJ

International Classification:

C10G 2302

US Classification:

208254H

Abstract:

A nitrogen containing feedstock is hydrodenitrified by passing the feed through at least two hydrodenitrification zones, with ammonia produced in the hydrodenitrification being purged from the system prior to the last hydrodenitrification zone to maintain a low ammonia partial pressure in the last hydrodenitrification zone. The ammonia is preferably purged by stripping ammonia from the liquid portion of the effluent withdrawn from the next to last hydrodenitrification zone. Improved denitrification is obtained by maintaining a low ammonia partial pressure in the last hydrodenitrification zone.
