Problems solved by technology

[0012] In practice, it turns out that with known drying devices for drying compressed gases, under certain conditions, such as in the case of insufficient regeneration of the dry reagent and its supersaturation, the dry reagent undergoes a complex decomposition process, which in Some cases can eventually lead to the failure of the drying device, for example in the case of silica gel in the drum (rotor) as the drying agent, because the bonding function of the silica gel is reduced, which leads to the loss of structural strength of the supporting glass fiber matrix, and also The adsorption function of silica gel decreases due to the hydrolysis and decomposition of the silica gel structure

Embodiment Construction

[0029] figure 1 A block diagram is shown, where each block lists a step of the method according to the invention, and where in some blocks a number of sub-steps are distinguished between them.

[0030] The method according to the invention for producing an adsorbent agent for treating compressed gases essentially consists of step 1A and step 1B, wherein step 1A provides a monolithic support structure and step 1B consists in producing a coating suspension containing the adsorbent.

[0031] In the next step 2, the aforementioned coating suspension is applied to the aforementioned support structure to form a coating, and finally in step 3, a heat treatment is applied to the resulting support structure with the coating obtained after step 2, thereby sintering The aforementioned coatings result in improved adsorbent reagents.

[0032] According to a preferred, but not essential, feature of the invention, a ceramic structure comprising cordierite is selected for the monolithic supp...

Description

technical field [0001] The present invention relates to a method of manufacturing an adsorbent for use in treating compressed gas, and more particularly, a method of manufacturing an adsorbent useful for drying compressed gas, such as compressed air. Background technique [0002] Adsorption devices in the form of drying devices for compressed gases are already known, these drying devices comprising containers in which drying reagents or desiccants are placed. The relevant container is provided with an inlet for supplying the compressed gas to be dried and an outlet for removing the dried gas. [0003] The drying agent concerned is usually realized in the form of a regenerable drying agent, or in other words after reaching a certain degree of saturation. This is true when the drying reagent extracts moisture from the gas to be dried, the drying reagent will gradually become saturated with the adsorbed moisture. Thus, after a period of use of the drying agent for drying comp...
