Assignee:

Zenon Environmental Inc. - Oakville

International Classification:

B01D 3900

US Classification:

210490, 21050023, 21050025, 21050042

Abstract:

An asymmetric membrane comprising a tubular polymer film in combination with a tubular braid on which the film is supported, requires the braid be macroporous and flexible, yet sufficiently strong to withstand continuous flexing, stretching and abrasion during use for microfiltration (MF) or ultrafiltration (UF). The specifications for a braid of a long-lived membrane are provided. A membrane is formed by supporting a polymer film in which particles of calcined -alumina are dispersed, on the defined tubular braid.

Filed:

Apr 21, 1978

Appl. No.:

5/898616

Inventors:

Kenneth P. Goodboy - Pittsburgh PA
James J. Koenig - Belleville IL

Assignee:

Aluminum Company of America - Pittsburgh PA

International Classification:

C01F 714

US Classification:

423628

Abstract:

A low soda pseudoboehmite gel is provided by reacting a NaAlO. sub. 2 solution with a NaHCO. sub. 3 solution having a concentration of less than 75 grams/liter and preferably less than 50 grams/liter. The soda content of the resulting AlO(OH) gel can be further lowered by repeated washing and/or redispersing (repulping) in water and/or further neutralization with a carboxylic acid having 1 to 6 carbon atoms.

Appl. No.:

6/170638

Inventors:

Kenneth P. Goodboy - Pittsburgh PA

Assignee:

Aluminum Company of America - Pittsburgh PA

International Classification:

B01J 2104

US Classification:

252463

Abstract:

An improved Claus catalyst is provided in the form of activated alumina in which sodium oxide concentration, LOI and surface area of the catalyst are carefully controlled to achieve increased sulfur conversion. Sulfur recovery is enhanced by choosing an alumina catalyst having properties which minimize chemisorption of sulfur dioxide on the catalyst at reaction conditions. Sodium oxide may be present in an amount of 0. 1 to 2. 5 wt % of the catalyst (1100. degree. C. calcined basis). The catalyst desirably has a surface area greater than 100 m. sup. 2 /g (BET) and an LOI (hydroxyl content as determined by heating from 400. degree. to 1100. degree. C. ) between 2. 0 and 6. 0 wt %. A method of producing the catalyst and a method of using the catalyst are also provided.

Aluminum Company of America - Pittsburgh PA

International Classification:

B01D 5304

US Classification:

55 71

Abstract:

A composite HCl adsorbent comprising about 50-95 wt % alumina and about 5-50 wt % Y zeolite wherein the molar ratio of SiO. sub. 2 to Al. sub. 2 O. sub. 3 is about 4. 5-6. The adsorbent is produced by admixing particles of alumina and acid-treated Y zeolite, agglomerating, aging and activating. The activated composite adsorbent has improved dynamic adsorption behavior for HCl compared with both the alumina and Y zeolite starting materials.

B01D 6100

US Classification:

208179

Abstract:

A process is described for purifying an oil-containing liquid to remove aqueous and solid impurities which comprises passing said liquid through a permeable inorganic membrane previously treated by contacting the membrane with an organic reactant selected from the group consisting of a phosphonic acid, a phosphinic acid, a monocarboxylic acid, a dicarboxylic acid, a boronic acid, a phosphoric acid ester and a precursor which decomposes upon contact with said inorganic membrane to form one of said organic reactants whereby the treated membrane is capable of separating aqueous and solid impurities from hydrocarbons in the oil-containing liquid.

International Classification:

B01D 6300

US Classification:

21032169

Abstract:

A method and cleaning system is disclosed for cleaning the outer surface of a fouled microfiltration (MF) or ultrafiltration (UF) semipermeable hollow fiber membrane after its initial stable transmembrane flux has been decreased to an unacceptably low level. The method is specifically applicable to any fiber used to withdraw purified water from dirty water, particularly water containing organic matter including beneficial bacteria and/or undesirable inorganic salts, where the viability of the bacteria population is to be maintained. The membrane is cleaned by flowing a cleaning fluid, preferably a biocidal oxidative electrolyte having an oxidizing anion and an associated cation through the clean, permeate-side of the membrane, at low pressure no more than the bubble pressure breakthrough, usually
