Изобретение относитса к физико-химическим методам анализа и может примен тьс в химической промышленности.The invention relates to physicochemical methods of analysis and can be applied in the chemical industry.
Известен способ сн ти изотерм адсорбции объемным методом по величине равновесного давлени 1 . Недостатком известного способа вл етс невысока точность замера.There is a known method for removing adsorption isotherms using the volumetric method according to the equilibrium pressure 1. The disadvantage of this method is the low accuracy of the measurement.
С целью устранени указанного недоста-рка дополнительно определ ют количество адсорбированного газа и объем мертвогоIn order to eliminate this deficiency, the amount of adsorbed gas and the volume of dead gas are additionally determined.
пространства, унифицируют указанные величины в величину давлени , преобразуют их в прюпорциональные электрические сигаалы и непрерывно регистрируют в виде кривой двухкоординатным самопишущим потенциоме ром.spaces, unify these values into pressure values, convert them into automatic electrical signals, and continuously record them in the form of a curve using a two-coordinate recording recorder.
На чертеже представлена схема реализации способа.The drawing shows a diagram of the implementation of the method.
Схема работает следующим образом.The scheme works as follows.
В сосуд 1, заполненный адсорбентом,In the vessel 1 filled with adsorbent,
непрерывно подают газ из газометра 2. Давление измер ют манометром 3 при по, сто нных значени х объема и температуры газометра. Изменени давлени в газометре , пропорциональные изменению количест- gas is continuously supplied from gasometer 2. Pressure is measured by pressure gauge 3 at constant values of volume and temperature of gas meter. The pressure changes in the gasometer are proportional to the change in the amount
ва газа, поданного на адсорбент, преобразуют в электрический сигнал и через сопротивление 4 регистируют двухкоординатным самопишущим приборюм 5. Установившеес равновесное давление газа над адсорбентом измер ют манометром 6. Измер емое давление преобразуют в электрические сигналы и через сопротивление 7 регистируют по другой оси прибора 5.The gas supplied to the adsorbent is converted into an electrical signal and recorded through resistance 4 with a two-coordinate recording device 5. The steady-state equilibrium gas pressure over the adsorbent is measured with a pressure gauge 6. The measured pressure is converted into electrical signals and through resistance 7 recorded along a different axis of the device 5.
Поправка на объем газа, заполн ющего свободное пространство адсорбера и коммуникации , вводитс при помощи сопротивлени 8, величина которогю определ етс пределами измерени манометра, геометрическим объемом системы, температурой и пределами измерени величины адсорбции. Сигнал с сопротивлени 8 вычитаетс из сигнала с сопротивлени 4. Это обеспечиваетс различной пол рностью напр жений, снимаемых с сопротивлений 8 и 4.A correction for the volume of gas filling the free space of the adsorber and the communication is entered using resistance 8, the value of which is determined by the measurement limits of the manometer, the geometric volume of the system, the temperature and the measurement limits of the adsorption value. The signal from the resistance 8 is subtracted from the signal from the resistance 4. This is ensured by the different polarities of the voltages taken from the resistances 8 and 4.
