摘要： PROBLEM TO BE SOLVED: To provide such a producing method of a high concn. ozone gas and its device that ozone can be efficiently concentrated by using a specified high silica ozone adsorbent having excellent ozone adsorptivity even in a system in the presence of water and by using the adsorbent to a temp. swing adsorption device. SOLUTION: In the production of a high concn. ozone gas, a TSA adsorption method is used. An ozone-contg. gas from an ozone generating device 1 is preliminarily cooled and introduced into an adsorption layer in adsorbing processes 8, 9 to allow an oxygen concentrated gas at a rather low temp. to flow from the adsorption layer. In the desorbing process, a purge gas at a rather high temp. is passed through the adsorption layer in the opposite direction to the gas flow in the adsorbing process so as to continuously recover a concentrated ozone gas. As for the ozone adsorbent, one or more kinds of adsorbents selected from high silica pentasyl zeolite, dealuminized faujasite and mesoporous silicate are used. The ozone-contg. gas from the ozone reservoir 1 is cooled by the oxygen concentrated gas at a rather low temp. effluent from the adsorption layer of the adsorbing process.

摘要： PROBLEM TO BE SOLVED: To provide such a storing method of ozone and its device that ozone is produced by using inexpensive electric power such as nighttime electric power and the produced ozone is stored by using a specified high silica adsorbent having large ozone adsorptivity and a high ozone holding rate even in a system in the presence of water, and that ozone can be supplied as required. SOLUTION: In the storing method of ozone, ozone is produced by operating an ozone generating device 1 and the obtd. ozone-contg. gas is supplied to an ozone reservoir 8 packed with an ozone adsorbent containing dealuminized faujasite and/or mesoporous silicate to adsorb and store ozone at -100 deg.C adsorption temp. The ozone-contg. gas is preliminarily cooled by using an oxygen concentrated gas flowing from the ozone reservoir 8. When ozone is to be used, operation of the ozone generating device is stopped and ozone is recovered from the ozone reservoir 8 by desorption by heating, purging and desorption by heating, reduced pressure desorption, reduced pressure purging and desorption, or reduced pressure purging and desorption by heating.

摘要： PROBLEM TO BE SOLVED: To solve the problems that the reduction of an equipment cost, the reduction of electric power consumption and the assurance of the simplicity of operation and the ease of maintenance are heretofore not possible. SOLUTION: This environment control storage method for fruit vegetables consists in maintaining the in-storage house gases of CO2 necessary for maintaining the freshness of the agricultural products of a storage house and removing volatile org. materials, such as ethylene, acetoaldehyde and terpene. An adsorption column 6 packed with high silica zeolite 5 is used in this method. In-storage house gases contg. the volatile org. materials are brought into contact with high silica zeolite 5 to adsorb the CO2 and the volatile org. materials under the conditions under which the concn. of the in-storage house gases contg. the volatile org. materials of the storage house is high and thereafter, the CO2 and volatile org. materials adsorbed to the high silica zeolite 5 are released outside the system.

摘要： PROBLEM TO BE SOLVED: To inexpensively separate an isotopic gas by using the adsorbent having a similar sized microhole as the molecular diameter of the isotopic gas and finishing an adsorption process before the adsorbing quantity of the isotopic gas reaches the saturated adsorbing quantity to increase the ratio of the isotopic gas more than in a vapor phase. SOLUTION: At the time of separating the isotope by adsorbing NH3 to an Na-A type zeolite, a gaseous starting material discharged from a gas holder 1 is introduced into an adsorption column 6 from a valve 5 through a mass rate controller 3. NH3 is adsorbed from the front side of the adsorption column 6 with valves 5 and 8 opened and valve 9 and 10 closed and gradually moves to the rear side. At the time of reaching a prescribed adsorption time, the adsorption column 6 is evacuated to vacuum by a vacuum pump 11 with the valves 5, 8 and 9 closed and the valve 10 opened and, when the absorption column 6 reaches a prescribed pressure, the valve 9 is opened and He is introduced at a flow rate corresponding to the displacement of the vacuum pump 11 into the adsorption column 6 by controlling a flow control valve 12 and the adsorbed NH3 is recovered from the rear side of the vacuum pump 11.

摘要： PROBLEM TO BE SOLVED: To efficiently recover and re-use an organic substance by extracting and removing the organic substance by a specific method when the subject zeolite is obtained by hydrothermal synthesis from a mixture obtained by adding the organic substance to a silica source in a sol state or a mixture of silica source with an alumina source. SOLUTION: A pentasil zeolite precursor containing an organic substance (e.g. tetrapropylammonium bromide) after hydrothermal synthesis is brought into contact with a solvent, preferably a fluid (e.g. CO2 ) under supercritical conditions or an alcohol (e.g. methanol) to extract and remove the organic substance. As a result, the organic substance can readily be removed and recovered without breaking network of aluminosilicate and the objective zeolite stabilized in quality is obtained and the cost of the organic substance can be reduced by reusing the recovered organic substance.

摘要： PURPOSE: To recover an organic material with high concentration without causing the deterioration of organic material and adsorbent by removing moisture from the organic material and moisture contg. gas with a moisture absorbent, adsorbing and removing the organic material under a relatively low temp. condition and releasing, liquefying and recovering the organic material under a relatively high temp. condition. CONSTITUTION: A silica based fiber carrying an Na-A type zeolite capable of selectively adsorbing only moisture from a system containing the organic material and moisture is packed in a dehumidifying tower 5 as the moisture absorbent 4. An off-gas is introduced into the dehumidifying tower 5 from a flow passage 1 to adsorb only moisture and the dry gas containing the organic material is cooled in a cooler 7 and is supplied to an adsorbing process zone 28 of an adsorbing tower 9. A high silica zeolite is packed into the adsorbing tower 9 as the adsorbent 8 adsorbing the organic material and the dry gas is discharged from the outlet. The adsorbent 8 is fed to a regenerating process zone 29 to release the organic material and to regenerate the adsorbent 8 with a purge gas 12 as a part of the dry gas 11 heated by a heater 13. The regenerated adsorbent 8 is cooled and reutilized and the released gas 15 is cooled, liquefied and recovered.

摘要： PURPOSE: To recover organic matter with low energy and at low temperature from gas containing both moisture and organic matter by making organic matter adsorbed at relatively low temperature using an adsorbent before adsorbing it at relatively high temperature and removing moisture at relatively low temperature using a moisture absorbent before regenerating the absorbent at relatively high temperature. CONSTITUTION: Off gas from a flow passage 1 is fed into an adsorption process region 25 of an adsorption tower 5 to adsorb organic matter at relatively low temperature. An adsorbent 4 that has adsorbed the organic matter is led to a regeneration process region 26, and purge gas 7 heated by a heater 8 is made to flow countercurrently to eliminate the organic matter and regenerate the adsorbent 4. After desorbing gas 10 containing the organic matter that has undergone value reduction and concentration is cooled, it is led to a dehumidifier 15 to adsorb moisture in the gas by a hygroscopic agent 14 and is turned into high concentration organic matter containing dry gas 17. The high concentration organic matter containing dry gas 17 is led to a low temperature liquefying device 22 to recover the organic matter as liquid recovered organic matter 23. On the other hand, the moisture absorbent 14 that has absorbed moisture enters a regeneration process region 29, and purge gas 18 that is a part of the dry gas 17 is heated and made to flow countercurrently, and the absorbed moisture is eliminated to regenerate the moisture absorbent 14.
