  • Patent number: 8772557
    Abstract: Processes are disclosed that achieve a high conversion of lignin to aromatic hydrocarbons, and that may be carried out without the addition of a base. Depolymerization and deoxygenation, the desired lignin convention steps to yield aromatic hydrocarbons, are carried by contacting a mixture of lignin and a solvent (e.g., a lignin slurry) with hydrogen in the presence of a catalyst. A preferred solvent is a hydrogen transfer solvent such as a single-ring or fused-ring aromatic compound that beneficially facilitates depolymerization and hinders coke formation. These advantages result in favorable overall process economics for obtaining fuel components and/or chemicals from renewable sources.

  • Patent number: 7008526
    Abstract: When a pitch composition prepared by mixing 100 parts by weight of mesophase pitch with 10 to 1,000 parts by weight of coal tar pitch, is heat-treated at a temperature of 500° C. or higher, it is possible to produce a high-density coke at a high yield while avoiding the foaming of the mesophase pitch. In addition, when the coke is graphitized at a temperature of 2,000° C. or higher, it is possible to obtain an artificial graphite having a high graphitization degree. Further, when the coke is first pulverized and then graphitized at a temperature of 2,000° C. or higher, it is possible to obtain a high-crystallinity graphite powder which can be suitably used as a carbon material for a negative electrode of non-aqueous solvent type secondary battery having a high discharge capacity and a high charge-discharge efficiency.

  • Patent number: 6867302
    Abstract: A process for producing organic substituted aromatic or heteroaromatic compounds including biaryl and biheteroaryl compounds in a two-step reaction. In the first step, the aromatic or heteroaromatic compound is borylated in a reaction comprising a borane or diborane reagent (any boron reagent where the boron reagent contains a B—H, B—B or B—Si bond) and an iridium or rhodium catalytic complex. In the second step, a metal catalyst catalyzes the formation of the organic substituted aromatic or heteroaromatic compound from the borylated compound and an electrophile such as an aryl or organic halide, triflate (OSO2CF3), or nonaflate (OSO2C4F9). The steps in the process can be performed in a single reaction vessel or in separate reaction vessels. The present invention also provides a process for synthesis of complex polyphenylenes starting from halogenated aromatic compounds.

    Abstract: Th invention provides a method of producing dialkylbiphenyls and trialkylbiphenyle efficiently using a continuous flow system. The method of continuously producing polyalkylbiphenyls comprises the following four steps: (1) a step of supplying reaction raw materials containing at least biphenyl and an olefin to a flow system reactor wherein the mol ratio of olefin/biphenyl is 0.3 to 3 at the inlet of the reactor and reacting the raw materials in the presence of a solid acid catalyst to obtain a reaction mixture containing monoalkylbiphenyls and dialkylbiphenyls, (2) a step of separating a fraction containing biphenyl and at least a part of monoalkylbiphenyls from the above reaction mixture, (3) a step of circulating the fraction separated in the step (2) to the reactor such that the ratio by weight of biphenyl to monoalkylbiphenyls is designed to be 0.

  • Publication number: 20030220498
    Abstract: A process for the production of compounds Ar—R1 by means of a cross-coupling reaction of an organometallic reagent R1—M with an aromatic or heteroaromatic substrate Ar—X catalyzed by one or several iron salts or iron complexes as catalysts or pre-catalysts, present homogeneously or heterogeneously in the reaction mixture. This new invention exhibits substantial advantages over established cross coupling methodology using palladium- or nickel complexes as the catalysts. Most notable aspects are the fact that (i) expensive and/or toxic nobel metal catalysts are replaced by cheap, stable, commercially available and toxicologically benign iron salts or iron complexes as the catalysts or pre-catalysts, (ii) commercially attractive aryl chlorides as well as various aryl sulfonates can be used as starting materials, (iii) the reaction can be performed under “ligand-free” conditons, and (iv) the reaction times are usually very short.
