摘要： The present invention relates to a carbon sorbent the can selectively remove platinum-group metals and other heavy metals such as tin without co-removing organic synthesis products including pharmaceutical intermediates and finished Active Pharmaceutical Ingredients (APIs). The carbon sorbents of the present invention are made from low-cost, high purity starting materials and the resulting carbon sorbents are also very pure. The carbon sorbents possess a combination of certain nitrogen and phosphorous groups combined with mesoporosity (2 to 50 nm diameter pores) that proves the high metal adsorption.

摘要： Sorbents and methods of using them for removing mercury from flue gases over a wide range of temperatures are disclosed. Sorbent materials of this invention comprise oxy- or hydroxyl-halogen (chlorides and bromides) of manganese, copper and calcium as the active phase for Hg0 oxidation, and are dispersed on a high surface porous supports. In addition to the powder activated carbons (PACs), this support material can be comprised of commercial ceramic supports such as silica (SiO2), alumina (Al2O3), zeolites and clays. The support material may also comprise of oxides of various metals such as iron, manganese, and calcium. The non-carbon sorbents of the invention can be easily injected into the flue gas and recovered in the Particulate Control Device (PCD) along with the fly ash without altering the properties of the by-product fly ash enabling its use as a cement additive. Sorbent materials of this invention effectively remove both elemental and oxidized forms of mercury from flue gases and can be used at elevated temperatures. The sorbent combines an oxidation catalyst and a sorbent in the same particle to both oxidize the mercury and then immobilize it.

摘要： Methods of making alkyl esters are described herein. The methods are capable of using raw, unprocessed, low-cost feedstocks and waste grease. Generally, the method involves converting a glyceride source to a fatty acid composition and esterifying the fatty acid composition to make alkyl esters. In an embodiment, a method of making alkyl esters comprises providing a glyceride source. The method further comprises converting the glyceride source to a fatty acid composition comprising free fatty acids and less than about 1% glyceride by mass. Moreover, the method comprises esterifying the fatty acid composition in the presence of a solid acid catalyst at a temperature ranging firm about 70° C. to about 120° C. to produce alkyl esters, such that at least 85% of the free fatty acids are converted to alkyl esters. The method also incorporates the use of packed bed reactors for glyceride conversion and/or fatty acid esterification to make alkyl esters.

摘要： A method of extracting fullerenes from a carbon matrix in which they are produced. The method is applicable to both fullerenes that exhibit greater than 0.1 mg/ml solubility in toluene and to fullerenes that are essentially insoluble in toluene, i.e., those exhibiting less than or equal to 0.1 mg/ml solubility. The method disclosed herein extracts more of the soluble fullerenes from the carbon matrix than extraction conducted by solely contacting with solvent. A method is also provided for creating salts of the extracted fullerenes.

摘要： The present invention provides block copolymers containing at least one block of a poly(heteroaromatic) polymer and at least two blocks of a non-conjugated polymer. The chemically different blocks of the copolymer are covalently bonded to each other in an alternating fashion through an appropriate linkage group. The poly(heteroaromatic) block may exist in its neutral or oxidized form, and when in the oxidized form, it associates with organic or inorganic counter-anions to balance the charge. The poly(heteroaromatic) polymer is an intrinsically conducting polymer (ICP), and when in the oxidized form it is electrically conducting. When the ICP block or blocks of the block copolymer are in the doped form, the block copolymer is electrically conducting. Preferably the conducting block copolymers have conductivities in the range 10−6-103 S/cm. Block copolymers of this invention are soluble or dispersible in water, one or more organic solvents, or in a mixture thereof at a level of at least about 0.1 g/liter.
