  • Patent number: 6833483
    Abstract: The invention disclosed relates to the production of alcohols. A first aspect of the invention relates to a process for production of alcohols, and in particular to a process for the catalytic hydration of an olefin to the corresponding alcohol in substantially anhydrous form, under selected mild reaction conditions, and using a selected catalyst. A second aspect of the invention relates to a process for dehydration of an azeotropic mixture, including a first alcohol and water. A hydration reaction between the water in the azeotropic mixture and an added olefin, under selected mild conditions, and using a selected catalyst, produces a product including a second alcohol corresponding to the olefin, and the first alcohol, in substantially anhydrous form.

  • Patent number: 6767465
    Abstract: A process for recovering fine coals and clarifying water for recycling features with three distinct mechanisms: hydrophobic extraction, electrolyte coagulation, and macromolecular flocculation, which if desired may be integrated into a single stage. The hydrophobic extraction is accomplished using oil to form a coal-in-oil mixture. The process water is clarified using a flocculants, more preferably a combination of coagulant and anionic flocculants. With a well defined reagent addition scheme, this process allows a combustible recovery greater than 88% at an ash content less than 11%, while producing a clean water containing less than 20 ppm suspended solids from a tailing's stream. The coal-in-oil mixture may be used as a fuel for example in coal-firing boilers and power generators.

  • Publication number: 20040072991
    Abstract: Human myelin basic protein (h-MBP) has a molecular weight of 18.5 KD and contains 170 amino acid residues. Synthetic peptides ranging in length from about 8 to 25 residues and covering the entire length of the protein have been produced. Antibodies to h-MBP (anti-MBP) were found to be neutralized by the synthetic peptides, in vitro, which span the h-MBP from about amino acid residue 61 to about amino acid residue 106. The peptides, which cover both the amino (about residues 1 to 63) and carboxy (about residues 117 to 162) terminals of h-MBP did not neutralize purified anti-MBP. Intrathecal administratin of peptide MBP(75-95), MBP(86-95), or MBP(82-98) produced complete binding-neutralization of free (F) anti-MBP with no change in bound (B) levels. A control peptide MBP35-58 had no effect on F or B anti-MBP levels. Intravenous administration of MBP(75-95), MBP(86-95), or MBP(82-98) resulted in significant decline of F and B CSF anti-MBP levels.
