CONSTITUTION:A mixed gas of CO, H2, etc. evolved from the device 1 is compressed by the compressor 3, through the adsorption columns 8 and 8' having the first half parts packed with active alumina for water adsorption and the last half parts packed with Na-X zeolite for CO2 adsorption, so that water and a CO2 gas in the mixed gas are adsorbed. The mixed gas containing CO, H2, N2, etc. is introduced to the CO adsorption columns 18 and 18'. The adsorption columns have been packed with A type zeolite obtained by blending Na-A type zeolite or Na-A type zeolite impregnated with Fe ion with a binder, molding the blend, heat-treating it, only CO is adsorbed, desorbed by the vacuum pump 20 at low pressure, and taken out as the highly-concentrated CO gas 21. The adsorption columns 8 and 8' and the CO adsorption column 18 and 18' for adsorption and desorption are changed alternately and used.

摘要： PURPOSE:To make it possible to keep the height of a fluidized bed constant, in the main body of a gassifying furnace having a pressure fluidized bed formed to the furnace bottom thereof, by detecting the height of the pressure fluidized bed by the differential pressure and controlling the ash discharge amount of as ash discharge means on the basis of the detection result. CONSTITUTION:A pressure fluidized bed 3 is formed to the furnace bottom of the main body 1 of a gassifying furnace and ash is discharged from the furnace bottom of the main body 1 by a means 8. Further, the height of the fluidized bed 3 is detected on the basis of differential pressure by a means 24 while the ash discharge amount of the means 8 is controlled on the basis of the output signal of the means 24 by a control apparatus 25. By this simple and inexpensive constitution, the height of the fluidized layer can be kept constant and a constant reaction ratio can always be obtained for coal particles different in reaction capacity.

摘要： PURPOSE:To reduce power basic unit and amount of an adsorbent, by packing a Ca-Na-A type zeolite in the upstream side of N2 adsorption columns and Na-X type zeolite on the downstream side thereof in producing oxygen with the N2 adsorption columns. CONSTITUTION:In production of oxygen with N2 adsorption columns, a mixed gas consisting essentially of oxygen and nitrogen, e.g. air, at room temperature or below under atmospheric pressure or above and 8atm or below is introduced into two adsorption columns 8 and 8' by a compressor 2. The nitrogen in the air is selectively adsorbed in the adsorption columns 8 and 8', and the resultant oxygen of high purity or oxygen-enriched gas is collected through valves 10, 11, 10' and 11' into a tank 12. On the other hand, the pressure of the adsorption columns 8 and 8' adsorbing the nitrogen is reduced to 0.05atm or above and 0.5atm or below to eliminate the nitrogen. Ca-Na-A type zeolite is packed in the upstream side of the adsorption columns 8 and 8', and Na-X type zeolite is packed in the downstream side thereof.

摘要： PURPOSE:To improve the yield of separated and recovered O2 in the process comprising the supply of air alternately to a pair of adsorption columns packed with N2- adsorbent, by carrying out the desorption of N2 from the N2-adsorbent under reduced pressure. CONSTITUTION:Sodium faujasite whuch is a zeolite mineral represented by Na-X is packed as the N2-adsorbent 9, 9' in a pair of N2-adsorption columns 8, 8'. Air 1 is compressed with a compressor 2, cleaned by passing through the column 4 for removing moisture and CO2, cooled with the refrigerator 20, and supplied to the bottom of the N2-adsorption column 8. The N2 in the air is adsorbed to the N2-adsorbent 9, and the remaining gas having high O2 content is discharged from the top valve 10 and charged in the O2-gas reservior 13. The N2-adsorption column 8' containing the N2- adsorbent 9' saturated with adsorbed N2 is evacuated with the vacuum pump 18 to effect the desorption of the adsorbed N2 and the regeneration of the adsorbent 9'. The regenerated adsorption column 8 is used in place of the column 8. In contrast with conventional process, the desorption of N2 from the N2 adsorbent is carried out without using a part of the separated O2 in the present process, and accordingly, the yield of the recovered O2 gas can be improved.

摘要： PURPOSE:To obtain an adsorbent of N2 wherein the amount of N2 to be adsorbed is increased under adsorption conditions at low temp. and low pressure and a conventional adsorption velocity of N2 is kept and the decrement in selectivity of said adsorption is low, by exchanging the specified amount of Na ion of Na faujasite for Ca ion and thereafter heat-treating the ion-exchanged material. CONSTITUTION:After at least 30-100% Na ion of Na faujasite represented as Na-X, Na-Y is ion-exchanged for Ca ion, the ion-exchanged material is heat-treated in the condition of >=450 deg.C to produce an adsorbent of N2 for low temp. In the adsorption towers 8, 8' of at least two towers wherein these adsorbents 9, 9' are packed, air is sent and pressure into the first adsorption tower 8 so that the inside of the tower 8 is regulated to the pressure of 1-3 atmospheric pressure, therefore N2 is adsorbed selectively and high pure O2 or O2-enriched air is discharged from said tower 8. On the other hand, the second adsorption tower 8' is reduced to the pressure of 0.5-0.8 atmospheric pressure, therefore the adsorbed N2 is discharged to regenerate said adsorbent and these all processes are performed under cooling conditions below room temp. As a result of this process, high pure O2 exceeding 99% is obtained easily with less power consumption.
