Abstract

The invention relates to the technical field of gas adsorption and desorption related to adsorbents. A gas adsorption testing device comprises a computer, a controller, a microbalance, a suspension rod, an electromagnet, a test chamber, a gas vent I, a permanent magnet, a steel wire, a displacement sensor, an induction coil, a standard sample, a support level I, a tray I, a support level II, a bracket, a tray II, a support level III, a connecting tube, a gas tube I, a sample chamber I, a gas tube II, a sample chamber II and a gas vent II. The design of two vertically arranged sample chambers is used. The gas adsorption testing device is suitable for studying absorption processes of two cases that absorption airflow passes through the device from top to bottom and from bottom to top and cancarry out a bidirectional absorption test on the gas; the test process is simple; the time for the absorption process is short; moreover, the contact area between the fluid and the gas is large, thereby accelerating the absorption process; and the sample chamber has gas tightness during gas absorption efficiency measurement, thereby improving the accuracy of the measurement result.

Description

technical field [0001] The invention relates to the technical field of gas adsorption and desorption related to adsorbents, in particular to a gas adsorption test device capable of performing bidirectional adsorption tests on gases. Background technique [0002] Adsorption is an important chemical operation process, which is widely used in petroleum, chemical industry, metallurgy, food, medicine and other fields. Its basic principle is to make the flowing gas or liquid contact and interact with the adsorbent, so that Part of the components are adsorbed by the adsorbent, so as to achieve the purpose of separating the gas or liquid to be adsorbed. The adsorbent can be liquid or solid, and can be a stationary phase or a mobile phase. The weighing method is a common method for studying the adsorption process. It studies the characteristics of adsorption capacity and density by weighing the weight of a certain mass of adsorbent before and after adsorption. It is impossible to si...
