  • Patent number: 8853458
    Abstract: Processes are disclosed for the conversion of a carbohydrate source to hexamethylenediamine (HMDA) and to intermediates useful for the production of hexamethylenediamine and other industrial chemicals. HMDA is produced by direct reduction of a furfural substrate to 1,6-hexanediol in the presence of hydrogen and a heterogeneous reduction catalyst comprising Pt or by indirect reduction of a furfural substrate to 1,6-hexanediol wherein 1,2,6-hexanetriol is produced by reduction of the furfural substrate in the presence of hydrogen and a catalyst comprising Pt and 1,2,6-hexanediol is then converted by hydrogenation in the presence of a catalyst comprising Pt to 1,6 hexanediol, each process then proceeding to the production of HMDA by known routes, such as amination of the 1,6 hexanediol. Catalysts useful for the direct and indirect production of 1,6-hexanediol are also disclosed.

  • Publication number: 20130331606
    Abstract: Processes are disclosed for the conversion of 1,6-hexanediol to adipic acid employing a chemocatalytic reaction in which 1,6-hexanediol is reacted with oxygen in the presence of particular heterogeneous catalysts including at least one of platinum or gold. The metals are preferably provided on a support selected from the group of titania, stabilized titania, zirconia, stabilized zirconia, silica or mixtures thereof, most preferably zirconia stabilized with tungsten. The reaction with oxygen is carried out at a temperature from about 100° C. to about 300° C. and at a partial pressure of oxygen from about 50 psig to about 2000 psig.

    Abstract: The present invention generally relates to processes for the conversion of glucose to caprolactam employing chemocatalytic oxidation and reduction reactions. The present invention also includes processes for the conversion of glucose to caprolactam via amido polyhydroxy acid products and amidocaproic acid or derivatives thereof. The present invention also includes processes that catalytically oxidize an amidopolyol to amidopolyhydroxy acid or derivatives thereof, and processes that catalytically hydrodeoxygenate amino or amido polyhydroxy acid or derivatives thereof to an amino or amidocaproic acid product. The amino or amidocaproic acid product may then be converted to caprolactam. The present invention also includes products produced by such processes and products producable from such products.

    Abstract: Described is a parallel batch reactor for effecting chemical reactions. The parallel batch reactor includes a plurality of reactor vessels for receiving components of a reaction, an inlet port for receiving pressurized fluid, and a plurality of valves configured to transfer fluid from the inlet port to the reactor vessels and fluidically isolate one or more of the reactor vessels from at least one of the other reactor vessels. The reactor further includes a pressure monitoring system comprising an array of pressure sensors configured to sense pressure in the reactor vessels. Each of the pressure sensors is aligned with one of the plurality of reactor vessels and located external to the reactor vessels and fluid passageways in fluid communication with the reactor vessels.

  • Patent number: 7655191
    Abstract: In one embodiment, a parallel batch reactor generally includes a plurality of reactor vessels and a plurality of valves configured to allow flow into the reactor vessels when a gas is supplied to the reactor at a pressure higher than a pressure within the reactor vessels and restrict flow from the reactor vessels. A method includes inserting chemical components into the reactor vessels, supplying a first gas to the reactor vessels to pressurize the reactor vessels, stopping supply of the first gas, and supplying a second gas to the reactor at a lower pressure than a pressure within the reactor vessels. The second gas passes through the valves and into the reactor vessels when the pressure within the reactor vessels drops below the pressure of the second gas.
