Halogenated graphene nanoplatelets, and production and uses thereof

Halogenated graphene nanoplatelets that are characterized by having, except for the carbon atoms forming the perimeters of the graphene layers of the nanoplatelets, (i) graphene layers that are free from any element or component other than sp2 carbon, and (ii) substantially defect-free graphene layers; the total content of halogen in the nanoplatelets is about 5 wt % or less calculated as bromine and based on the total weight of the nanoplatelets. Processes for producing such nanoplatelets and various end uses for such nanoplatelets are also described. ... Albemarle Corporation

Injection of sorbents in ductwork feeding wet scrubbers for mercury emission control

Methods and systems are described for more effectively sequestering or removing mercury from flue gases. This is accomplished by feeding an adsorbent into the flow of flue gas in ductwork leading into a scrubber housing containing a wet scrubber composition and providing a residence time sufficient to enable the mercury to be sequestered by the adsorbent.. ... Albemarle Corporation

Highly reactive metal hydrides, process for their preparation and use

The invention relates to powdery, highly reactive alkali and alkaline earth hydride compounds, and to mixtures with elements of the third main group of the periodic table of elements (pte) and to the preparation thereof by reacting alkali or alkaline earth metals in the presence of finely dispersed metals or compounds of the third main group of the pte, wherein the latter have one or more hydride ligands or said hydride ligands are converted in situ, under the prevailing reaction conditions, i.e., in the presence of hydrogen gas or another h source, into hydride species, and to the use thereof for the preparation of complex hydrides and organometallic compounds.. . ... Albemarle Corporation

Method for producing metal organyls

The invention relates to a method for producing organometallic compounds rmn (m=alkali or alkaline earth element, r=alkyl residue) where n=valence of the metal m and r=alkyl residue with 2 to 18 c atoms, in which method an olefin is hydrometalated in an alkyl methyl ether, or in a solvent mixture containing an alkyl methyl ether, by means of the metal m and in the presence of a hydrogen source and in the presence of a transition metal catalyst, wherein the molar ratio between alkyl methyl ether and metal m is at least 0.01:1 and at most 50:1.. . ... Albemarle Corporation

Process for concentration of lithium containing solutions

A forward osmosis process for concentration of lithium-containing salt solutions is described. A difference in osmotic pressure between a lithium-containing salt solution and a second salt solution of higher osmotic pressure is used as a driving force to pass water through a semi-permeable forward osmosis membrane from said lithium-containing salt solution of lower osmotic pressure to the salt solution of higher osmotic pressure. ... Albemarle Corporation

Hydrotreating catalyst containing metal organic sulfides on doped supports

A catalyst comprising: a catalyst support; at least one group vib metal component; at least one group viii metal component; at least one mercapto-carboxylic acid; wherein the catalyst support contains at least one dopant comprising either boron, and/or silicon, and/or phosphorusin the range of about 1 to about 13 wt %, expressed as an oxide and based on the total weight of the catalyst for each dopant added; and wherein the amount of the at least one mercapto-carboxylic acid is in the amount from about 0.4 to about 3 equivalents to the sulfur amount necessary for forming sulfides of the group vi and viii components.. . ... Albemarle Corporation

Process for preparing metal powders and metal hydride powders of the elements ti, zr, hf, v, nb, ta and cr

The oxide used has an average particle size of 0.5 to 20 μm, a bet specific surface of 0.5 to 20 m2/g and a minimum content of 94 wt %.. ... Albemarle Corporation

Process for the preparation of 4-phenyldibenzothiophene

The invention relates to a novel method for the preparation of 4-phenyldibenzo[b,d]thiophene which can be conducted in one pot up to the thiophene ring formation. The synthesis is based upon dihalobenzenes and phenyllithium, which are readily obtainable, and can give higher yields (based upon either reactant) than the yields current methods, which use a synthetic pathway based upon dibenzo[b,d]thiophene.. ... Albemarle Corporation

Microbiocidal control in the processing of poultry

This invention provides processes comprising contacting at least one unopened defeathered poultry carcass with water containing a microbiocidal composition, optionally opening and eviscerating at least one unopened defeathered poultry carcass that was wetted; subjecting at least one eviscerated poultry carcass to inside-outside washing with water containing a microbiocidal composition; placing at least one eviscerated poultry carcass in a chill tank into contact with chill water containing a microbiocidal composition; contacting parts of poultry resulting from processing of poultry containing a microbiocidal composition. The water in these processes contains a microbiocidal composition comprising i) one or more surfactants and ii) a microbiocidal amount of a biocide. ... Albemarle Corporation
