Способ получения водорода

Номер: RU2792643C1

Изобретение может быть использовано для обеспечения водородным топливом и перекисью водорода энергетических установок с тепловыми двигателями или с электрохимическими генераторами на топливных элементах, для получения водорода для технологического использования. В способе получения водорода при разложении молекул воды монохроматическим излучением вода используется в фазовом состоянии льда. Поверхность блока льда облучается с частотой не менее 1 Гц монохроматическим излучением ультрафиолетового диапазона. Проводится разрыв водородных связей молекул льда облучением на длине волны излучения 166,5 нм. При этом проводят облучение поверхности льда с плотностью энергии не менее 11,7 Дж/см2. С поверхности льда раздельно собирают выделившийся в результате разрыва водородных связей молекул льда газообразный водород и жидкую фазу перекиси водорода. Изобретение позволяет упростить получение водорода, снизить энергозатраты на его производство, повысить его выход. 3 ил.

Heating or cooling media are brought to pressure by passage through circular segments, then passed through a double-wall fitted to a graphite reaction vessel. The reaction column is divided by fixed or loose installations e.g. perforated trays, bubble-plates, etc., of the required size, so that remixing is prevented, and optimum conditions are attained. Photochemical reactns. may be induced by rays of UV light passed through opening in the column wall e.g. of quartz, and when suitable measuring and regulating instruments are switched on the reactn. may proceed continuously. In an example, the apparatus has been used in the preparation of the insecticide "Melipax" by UV-induced reactn. between camphene and Cl2.

Liquids are treated in the form of film or of spray, or in a combination of both, and preferably in a state of turbulence such as is obtained by passing over plates with a waved or other irregular surface. Solids are treated in thin layers on surfaces transparent to the rays used, thus permitting radiation on both sides. The irradiation may be accompanied by an electrical treatment; it may be conducted under pressure, in vacuo, or in a deoxidizing atmosphere.

It is essential that the step of alkaline extraction includes introducing the chlorinated irradiated benzene into the chamber of a multi-stage contactor in one direction and introducing water thereinto in the other direction in a volume of benzene to water of 0.5 to 4.0, maintaining the pH of the water from 7 to 12 and the temperature from 40-80 DEG C., thereby hydrolysing the unstable chlorinated contaminants in the benzene into thermally stable compounds which remain as bottoms ...

A generator for processing gases to be delivered to a process chamber used to process a substrate includes a housing that encloses an internal volume. An ultraviolet (UV) bulb is disposed within the internal volume of the housing. The UV bulb has a bulb diameter that fits within the internal major dimension of the housing. A first region, which surrounds the UV bulb, channels a first gas around the UV bulb to cool the UV bulb. A second region, which surrounds the first region, channels a second gas between an input to and an output from the housing. The second region is oriented relative to the UV bulb such that UV energy therefrom interacts with the second gas as this gas flows through the second region. The interaction of the UV energy with the second gas results in the generation of a gas mix that is supplied from the output of the housing into the process chamber, where at least one component of the gas mix is to be used in processing of the semiconductor substrate.

Method for recovering cyanide from a barren solution

Номер: US20170081202A1

A process is disclosed for recovering cyanide used to leach gold or silver from ore. In the course of leaching gold or silver from ore, a barren solution is generated. A portion of the barren solution containing sodium cyanide is recycled to the cyanidation process while blowdown from the barren solution is subjected to pre-treatment, UV photodissociation and pH adjustment. Ultimately, a volatile hydrocyanic acid is formed and is absorbed into a sodium hydroxide solution through the employment of a gas-filled membrane. This forms sodium cyanide that can be recycled and used in the cyanidation process to leach gold or silver from ore.
