  • Patent number: 8592633
    Abstract: Methods and systems for electrochemical conversion of carbon dioxide to carboxylic acids, glycols, and carboxylates are disclosed. A method may include, but is not limited to, steps (A) to (D). Step (A) may introduce water to a first compartment of an electrochemical cell. The first compartment may include an anode. Step (B) may introduce carbon dioxide to a second compartment of the electrochemical cell. The second compartment may include a solution of an electrolyte and a cathode. Step (C) may apply an electrical potential between the anode and the cathode in the electrochemical cell sufficient to reduce the carbon dioxide to a carboxylic acid intermediate. Step (D) may contact the carboxylic acid intermediate with hydrogen to produce a reaction product.

  • Publication number: 20120085658
    Abstract: An electrochemical cell having a cation-conductive ceramic membrane and an acidic anolyte. Generally, the cell includes a catholyte compartment and an anolyte compartment that are separated by a cation-conductive membrane. While the catholyte compartment houses a primary cathode, the anolyte compartment houses an anode and a secondary cathode. In some cases, a current is passed through the electrodes to cause the secondary cathode to evolve hydrogen gas. In other cases, a current is passed between the electrodes to cause the secondary cathode to evolve hydroxyl ions and hydrogen gas. In still other cases, hydrogen peroxide is channeled between the secondary cathode and the membrane to form hydroxyl ions. In yet other cases, the cell includes a diffusion membrane disposed between the secondary cathode and the anode. In each of the aforementioned cases, the cell functions to maintain the pH of a fluid contacting the membrane at an acceptably high level.

  • Patent number: 7332067
    Abstract: A process for the preparation of ?-substituted carboxylic acids from the series including ?-hydroxycarboxylic acids and N-substituted-?-aminocarboxylic acids by cathodic carboxylation with carbon dioxide of a compound corresponding to the general formula R1—C(?X)R2 which is constituted by aldehydes, ketones or N-substituted imines. In the past, that carboxylation has taken place in an undivided electrolytic cell with the use of a sacrificial anode. As described herein, the carboxylation takes place in the absence of a sacrificial anode in an electrolytic cell divided by a separator, at a diamond film cathode. The anode is formed of a material which is stable under electrolytic conditions; in particular, it is a diamond film electrode. The catholyte includes an organic solvent and a conducting salt.

  • Patent number: 6880703
    Abstract: A floral transport apparatus to facilitate the transportation and delivery of floral arrangements is disclosed. The floral transport apparatus includes a hard plastic container housing a support carriage having a set of longitudinal elastic bands and a set of lateral elastic bands stretched tightly over a box frame to form an upper and lower mesh. The floral arrangement is held securely in the gaps between the tensioned bands of the upper and lower mesh to prevent lateral displacement which would otherwise result in tipping of the floral arrangement. The floral transport apparatus provides a means for carrying many floral arrangements of various sizes simultaneously. Moreover, the floral transport apparatus is easily portable and manageable by a single delivery person and can be washed to keep the apparatus attractive in view of floral customers and potential floral customers.
