摘要: The invention is related to a process for preparing a iodinating X-rays contrast agent. More specifically, it relates to a process for the preparation of N,N′-bis-(2,3-dihydroxypropyl)-5-hydroxy-2,4,6-triiodo-1,3-benzenedicarboxaniide (I) by electrochemical iodination of N,N′-(2,3-dihydroxypropyl)-5-hydroxy-1,3-benzenedicarboxamide (II) with molecular iodine (I2) which is in situ electrochemically generated from a source of iodide ions (I−). The iodide ions (I−) are obtained by the dissolution of hydrogen iodide (HI) or an alkali metal iodide in the reaction medium or produced during the reaction of N,N′-(2,3-dihydroxypropyl)-5-hydroxy-1,3-benzenedicarboxamide with I2. The invention also relates to the use of the intermediate compound of formula (I), obtained through the above electrochemical iodination of compound (II), in the preparation of N,N′-bis[2,3-dihydroxypropyl]-5(hydroxyacetyl)methylamino]-2,4,6-triiodo-1,3-benzenedicarboxamide (iomeprol).

摘要: An electrolytic synthesis system is equipped with an electrolysis device, a synthesis device, a gas adsorption type storage battery, and a control device. The gas adsorption type storage battery adsorbs, to electrodes thereof, carbon dioxide gas within the atmosphere during charging, and releases the carbon dioxide gas that was adsorbed to the electrodes, during discharging. When an adsorption amount of the carbon dioxide gas adsorbed to the electrodes exceeds a predetermined first threshold value, the control device controls a discharging switch and thereby initiates discharging of the gas adsorption type storage battery.

摘要: Large scale exploitation of Solar energy is proposed by using floating devices which use solar energy to produce compressed hydrogen by electrolysis of deep sea water. Natural ocean currents are used to allow the devices to gather solar energy in the form of compressed hydrogen from over a large area with minimum energy transportation cost. The proposal uses a combination of well understood technologies, and a preliminary cost analysis shows that the hydrogen produced in this manner would satisfy the ultimate cost targets for hydrogen production and pave the way for carbon free energy economy.

摘要: The present invention relates to energy storage systems and reactors useful in such systems. Inventive reactors comprise a reaction vessel defining an inner volume and a compensation element, whereby said inner volume is filled with a fixed bed that is free of cavities and that comprises particles of formula (I), FeOx (I), where 0≤x≤1.5; said compensation element is adapted to adjust said inner volume. The reactors are inherently explosion proof and thus suited for domestic use. The systems are useful for compensating long-term fluctuations observed in production of renewable energy.

摘要: The invention concerns a process and modular system for producing formic acid from a source of carbon dioxide. The process according to the invention comprises (a) a carbon capture step wherein a source of carbon dioxide is contacted with an alkaline solution to obtain a solution comprising carbonate and/or bicarbonate; optionally (b) subjecting the solution comprising carbonate and/or bicarbonate to alkaline water electrolysis, wherein carbonate present in the solution comprising carbonate and/or bicarbonate is converted to bicarbonate and H2O is converted into H2 and O2; (c) subjecting the solution comprising carbonate and/or bicarbonate to a hydrogenation step in the presence of a catalyst to obtain a solution comprising formate; and (d) subjecting the solution comprising formate obtained in step (c) to bipolar membrane electrodialysis to obtain a concentrated formic acid solution and a recovered alkaline solution, wherein the recovered alkaline solution obtained in step (d) is recycled back to step (a). The concentrated formic acid solution obtained from step (d) may be subjected to a hydrogenation step in the presence of a hydrogenation catalyst to obtain a concentrated formaldehyde solution.

摘要: [Task] Provided is a manufacturing method of butadiene that can reduce carbon dioxide emissions.
[Solution] A manufacturing method of butadiene includes an electrolytic reduction process 2 that produces ethylene and oxygen from carbon dioxide and water as a raw material by electrolytic reduction, a butene producing process 3 that produces butene by dimerizing the ethylene produced in the electrolytic reduction process, a mixing process 4 that prepares a mixed gas by mixing the oxygen produced in the electrolytic reduction process, the butene produced in the butene producing process, and air, and a butadiene producing process 5 that produces butadiene by heating the mixed gas and oxidatively dehydrogenating the butene, wherein carbon dioxide by-produced in the butadiene producing process is used as a portion of the raw material in the electrolytic reduction process.-

摘要: Power is provided to an electrochemical cell. The electrochemical cell includes an anode side and a cathode side. A solution is flowed to the anode side. The solution includes hydrogen sulfide dissolved in water. Water is flowed to the cathode side. The water flowed to the cathode side can be in the form of steam. Providing power to the electrochemical cell facilitates production of sulfur dioxide on the anode side. Providing power to the electrochemical cell facilitates production of hydrogen on the cathode side. A membrane separating the anode side from the cathode side prevents flow of hydrogen sulfide, water, and sulfur dioxide from passing through the membrane while allowing hydrogen cations and oxygen anions to pass through the membrane. Sulfur dioxide is flowed out of the anode side. Hydrogen is flowed out of the cathode side.
