Recovery And Recycle Of Molybdenum Values From Coal Liquefaction Residue
US Patent:
4374100, Feb 15, 1983
Filed:
Jun 30, 1982
Appl. No.:
6/393987
Inventors:
Roger F. Sebenik - Ann Arbor MI
Calvin J. Hallada - Ann Arbor MI
Henry F. Barry - Ann Arbor MI
George A. Tsigdinos - Ann Arbor MI

Assignee:
Amax Inc. - Greenwich CT
International Classification:
C01G 3900
US Classification:
423 56
Abstract:
The residue from a Mo-catalyzed coal liquefaction process is treated to recover the Mo in a form in which the Mo can easily be recycled and reused as a catalyst for coal liquefaction. The process includes intimately mixing the residue with alkali in excess of the stoichiometric amount required for water-soluble molybdate formation, subjecting the mixture to an oxidative roast at about 600. degree. C. to about 800. degree. C. for up to about one hour, leaching the roasted product with water to extract Mo values into solution, and then carrying out a series of steps involving acidifying and ammoniating the solution to form a Mo-bearing precipitate which is recovered and dissolved in aqueous ammonium hydroxide to form a solution which can be applied to coal to catalyze coal liquefaction.
Flame And Smoke Retardant Styrene Polymer Composition
US Patent:
3956231, May 11, 1976
Filed:
Sep 3, 1974
Appl. No.:

Henry F. Barry - Ann Arbor MI
Assignee:
Amax Inc. - New York NY
International Classification:
C08J 320
US Classification:
260 4214
Abstract:
A flame retardant styrenic synthetic polymer containing a flame retardant agent comprising a mixture of a molybdenum compound selected from the group consisting of molybdenum trioxide, ammonium dimolybdate, and ammonium heptamolybdate, in combination with a halogenated hydrocarbon compound selected from the group consisting of halogenated aromatic compounds, halogenated cyclic aliphatic compounds, and mixtures thereof.
Molybdate Corrosion Inhibiting Pigment And Method For Preparing Same
US Patent:
3969127, Jul 13, 1976
Filed:
Mar 10, 1975
Appl. No.:
5/556593
Inventors:
Dennis R. Robitaille - Detroit MI
Mark S. Vukasovich - Ann Arbor MI
Henry F. Barry - Ann Arbor MI

Henry F. Barry - Ann Arbor MI
Assignee:
The Sherwin-Williams Company - Cleveland OH
International Classification:
C09C 102, C09C 104
US Classification:
106292
Abstract:
A method for preparing an extended corrosion inhibiting pigment for use in formulating protective coatings for ferrous substrates in which a particulated inert carrier is slurried in an aqueous solution in the presence of molybdic oxide, to which a metal oxide of zinc, calcium, strontium and/or barium is added in a manner to effect a deposition of the corresponding metal molybdate on the carrier particles, whereafter the coated carrier is separated, dried and calcined at an elevated temperature.
