  • Patent number: 8426665
    Abstract: When producing hydrocarbons from fatty acid esters contained in fats or fat oils, the fatty acid esters initially are split up by hydrolytic decomposition into a first stream containing crude alcohol and water and a second stream containing free fatty acids, and subsequently the free fatty acids of the second stream are hydrogenated with hydrogen to obtain saturated hydrocarbons.

  • Patent number: 7459597
    Abstract: A feedstock originating from renewable sources is converted to branched and saturated hydrocarbons without heteroatoms in the diesel fuel distillation range by skeletal isomerisation and deoxygenation carried out by hydrodeoxygenation or alternatively by combined decarboxylation and decarbonylation reactions, whereby the consumption of hydrogen is decreased.

  • Patent number: 7147800
    Abstract: A method for making platform molecules comprising: reacting 4-alkoxy benzoyl chloride with R2-hydroquinone under first conditions effective to produce bis 1,4[4-alkoxy-benzoyloxy]-R2-phenylene comprising bis terminal alkoxy groups wherein R2 is a bulky organic group; and, subjecting the bis 1,4[4-alkoxy-benzoyloxy]-R2-phenylene to second conditions effective to selectively cleave the bis terminal alkoxy groups to produce a solution comprising complexes comprising diphenolic platform molecules comprising bis terminal hydroxyl groups, the second conditions also being effective to precipitate the complexes out of the solution.

  • Patent number: 7094943
    Abstract: Multifunctional liquid phase carriers (LPCs) and methods of using LPCs for the preparation of biopolymers are provided. The LPCs are highly symmetrical compounds that possess more than two points of attachment for biopolymer synthesis. The LPCs have the formula Sp(X1)n, where Sp is a highly symmetrical moiety such that all X1 groups are equivalent. X1 is a functional group that is suitable for biopolymer synthesis, including OH, SH, NH2, COOH and the like. Biopolymers that may be produced using the methods provided include oligonucleotides, peptides, protein nucleic acids (PNAs) and oligosaccharides. Analogs of the biopolymers may also be prepared using the methods.

  • Patent number: 6570045
    Abstract: Disclosed are a method of solidifying a low-boiling-point hydrocarbon, wherein the low-boiling-point hydrocarbon (including hydrocarbons which are gaseous at ordinary temperature) is brought into contact with a metal salt of an aliphatic carboxylic acid, and if necessary a high-boiling-point hydrocarbon, suspended in water, to form a solid aggregate substance, a method of handling the low-boiling-point hydrocarbon, wherein the solid aggregate substance is stored or transported, and a method of regenerating the low-boiling-point hydrocarbon, wherein the solid aggregate substance is decomposed by opening or heating, to obtain the low-boiling-point hydrocarbon. According to the methods, a wide variety of gaseous and highly volatile liquid hydrocarbons can be safely and easily solidified without using harmful reagent, and during storage, transportation, etc., the gaseous hydrocarbons and highly volatile liquids can be handled as a solid material.
