Description
РТедостатком известного способа получени водорода из ферросилици и водного раствора едкого натра вл етс необходимость подогревани воды даже при температурах воздуха пор дка 15°.The downstream of a known method for producing hydrogen from ferrosilicon and an aqueous solution of caustic soda is the need to heat water, even at air temperatures of the order of 15 °.
Применение описываемого способа позвол ет получать водород из ферросилици и водного раствора едкого натра без подогревани воды и дает возможность ускорить реакцию взаимодействи указанных компонентов.The application of the described method makes it possible to obtain hydrogen from ferrosilicon and an aqueous solution of caustic soda without heating the water and makes it possible to accelerate the reaction of the interaction of these components.
Это достигают тем, что процесс ведут в присутствии добавок 5- 15% алюмини , например, в виде алюминиевого порошка марки АПВ.This is achieved by the fact that the process is carried out in the presence of additives 5-15% aluminum, for example, in the form of aluminum powder brand APV.
Добавка небольших количеств алюмини дает достаточный тепловой эффект за счет реакции алюмини со ш,елочью, в результате чего начинаетс выделение водорода. Манометр показывает давление уже через 1-4 мин. после загрузки газогенератора, в зависимости от количества и качества добавл емого алюмини .The addition of small amounts of aluminum gives a sufficient thermal effect due to the reaction of aluminum with sh, alkali, as a result of which hydrogen evolution begins. The pressure gauge shows the pressure after 1-4 minutes. after loading the gas generator, depending on the quantity and quality of the added aluminum.
Способ удобен дл применени в услови х севера, аэрологических станций, а также в полевых и экспедиционных услови х, в газогенераторах высокого и низкого давлени .The method is suitable for use in the conditions of the north, upper-air stations, as well as in field and expeditionary conditions, in high and low pressure gas generators.
Пример 1. В газогенератор АВГ-40 (газогенератор высокого давлени ) внос т смесь, состо шую из 1187,5 г ферросилици и 62,5 г алюминиевого порошка марки АПВ (алюминий составл ет 5% смеси), 900 г едкого натра и 6 л воды. Температура воды 9,5°, окружаюшего воздуха 1Г.Example 1. A mixture consisting of 1187.5 g of ferrosilicon and 62.5 g of aluminum powder of the AR brand (aluminum of 5% of the mixture), 900 g of caustic soda and 6 l are introduced into the AVG-40 gas generator (high pressure gas generator). water. Water temperature is 9.5 °, ambient air is 1G.
Реакци начинаетс сразу, что отмечаетс по шипению выдел юпдегос газа, через 3 мин. после начала реакции отмечаетс давление 2 атм. От 3 до 4 мин. давление поднимаетс до 44 атм. Наибольшее давление 62 аглг наступает через 14 мин. после начала реакции. Выдел етс водорода с полной подъемной силой 1810 г.The reaction starts immediately, as indicated by the hiss of the release of gas, after 3 minutes. after the start of the reaction, a pressure of 2 atm is noted. 3 to 4 min. the pressure rises to 44 atm. The highest pressure 62 aggl occurs in 14 minutes. after the start of the reaction. Hydrogen is evolved with a total lift force of 1810.
Пример 2. В газогенератор Г-3 внос т 2 кг ферросилици , 1,5 кг едкого натра и 14 л воды со льдом дл того, чт(обы поглотитьExample 2. 2 kg of ferrosilicon, 1.5 kg of caustic soda and 14 liters of water with ice are introduced into the G-3 gas generator in order to take into account (absorb

В течение 1,5 час. реакп и дк; начипаетс , никаких признаков выделени газа не обнаруживаетс . Температура за это врем поднимаетс до 4-5°. Within 1.5 hours rekrep and dk; On the ground, no signs of gas evolution are detected. The temperature during this time rises to 4-5 °.
Далее дл вызова начала реакции добавл ют 200 г алюминиевого порошка марки АПВ (10% от веса ферросилици ).Then, to call the start of the reaction, 200 g of aluminum powder of the AR brand (10% by weight of ferrosilicon) are added.
Реакци начипаетс сразу, что отмечаетс по шипению выдел юш;егос газа. Водород поступает в оболочку через 3-4 мин. после добавки порошка АПВ.The reaction begins immediately, as indicated by the hiss of the release of gas. Hydrogen enters the shell in 3-4 minutes. after the addition of powder AR.
В период интенсивнор реакцип добавл ют из запасного бачка отдельными порци ми еш;е 2 кг ферросилици . За 35 мин. от начала реакции выдел етс 3310 г водорода с полпой подъемной силой.During the intensive period, the reaction is added from the spare tank in separate portions of eh; e 2 kg of ferrosilicon. 35 min. from the start of the reaction, 3,310 g of hydrogen is released with a full lift.
Из опыта видно, что количество щелочи при добывании водорода с помощью ферросилици в газогенераторе низкого давлени типа Г-3 может быть уменьшено на 30% по сравнению с газогенератором высокого давлени типа АВГ-40.From the experiment it is clear that the amount of alkali in the production of hydrogen using ferrosilicon in a low-pressure gas generator of type G-3 can be reduced by 30% compared with a high-pressure gas generator of type AVG-40.
