摘要： In various embodiments, the invention provides electro-chemical processes for reduction of carbon dioxide, for example converting carbon dioxide to formate salts or formic acid. In selected embodiments, operation of a continuous reactor with a three dimensional cathode and a two-phase (gas/liquid) catholyte flow provides advantageous conditions for electro-reduction of carbon dioxide. In these embodiments, the continuous two-phase flow of catholyte solvent and carbon dioxide containing gas, in selected gas/liquid phase volume flow ratios, provides dynamic conditions that favour the electro-reduction of COs at relatively high effective superficial current densities and gas space velocities, with relatively low reactor (cell) voltages ( 0.1) may provide greater than equilibrium CO 2 concentrations in the liquid phase, also facilitating relatively high effective superficial current densities. In some embodiments, these characteristics may for example be achieved at catholyte pH > 7 and relatively low CO 2 partial pressures (
摘要翻译：在各种实施方案中，本发明提供用于还原二氧化碳的电化学方法，例如将二氧化碳转化成甲酸盐或甲酸。在选定的实施方案中，具有三维阴极和两相（气/液）阴极电解液流的连续反应器的操作为二氧化碳的电还原提供了有利的条件。在这些实施方案中，在选定的气/液相体积流量比下，阴极电解液溶剂和含二氧化碳气体的连续两相流提供了动态条件，其有利于在相对高的有效表面电流密度和气体空间下电还原CO 速度，相对较低的电抗器（电池）电压（<10伏）。在一些实施方案中，阴极室中相对较高的内部气体滞留（在内部气体与液相体积比> 0.1时表现出来）可以在液相中提供大于平衡的CO 2浓度，也促进相对较高的有效表面电流密度。在一些实施方案中，这些特性可以例如在阴极电解液pH> 7和相对低的CO 2 /分压（<10巴）下实现。在一些实施例中，这些特性可以例如在接近绝热条件下实现，其中阴极电解液出口温度高达约80℃。

摘要： An acid or base is generated in an aqueous solution by the steps of: (a) providing a source of first ions (40) adjacent an aqueous liquid in a first acid or base generation zone (50), separated by a first barrier (46) (e.g., anion exchange membrane) substantially preventing liquid flow and transporting ions only of the same charge as said first ions, (b) providing a source of second ions of opposite charge (40) adjacent an aqueous liquid in a second acid or base generation zone (48), separated by a second barrier (44) transporting ions only of the same charge as the second ions, and (c) transporting ions across the first barrier by applying an electrical potential (52, 54) through said first and second zones and a base-containing aqueous solution in the other one which may be combined to form a salt (62). Also electrolytic apparatus for performing the above method. The product solutions can be used as an element for a chromato graphic separation medium (70). The element can be regenerated in order to reuse the ions by means of a membrane suppressor (74).

摘要： A HOCl manufacturing system is disclosed for production of high potency, safe, consistently pure, stable, authentic HOCl in a deployable, portable, high volume, localized manufacturing unit. The electrolysis method uses a deployable, remote-controlled manufacturing system. The method includes: controlling water flow rate into an electrolysis chamber by providing feedback controlled water pressure; applying feedback controlled current to the electrolysis chamber via an adjustable and high-current power supply; adding sodium chloride brine, via a feedback controlled actuator, to an anode chamber inlet and creating an aqueous mixture; adding sodium hydroxide, via a feedback controlled actuator, to the aqueous mixture; and producing aqueous hypochlorous acid free from hypochlorites, phosphates, oxides, and stabilizers.
