摘要： PURPOSE:To enhance the recovery ratio of product gas, in a pressure swing adsorbing process, by returning a part of the exhaust gas of an adsorbing tower in a regeneration process to the supply line for gas to be purified in an adsorbing tower in a purifying process. CONSTITUTION:Stock gas is compressed by a compressor 21 to be introduced into an adsorbing tower A and N2 is removed by adsorption while product H2 is taken out. An adsorbing tower B is reduced in pressure to atmospheric pressure from an exhaust valve 3b and N2 desorbed along with residual H2 is returned to a stock gas line 11 through a pressure reducing valve 9 and a valve 14. Subsequently, a part of product H2 is introduced into the adsorbing tower B through a pressure reducing valve 6 and a valve 4b to wash an adsorbent and exhaust gas is returned to the stock gas line 11 through the pipe 14 and, subsequently, the adsorbing tower B is again pressurized by product H2-gas to prepare the next adsorbing process. Because the concns. of N2 in exhaust gases at the time of evacuation and washing rise by repeating the processes, a part of the exhaust gas is purged from a valve 10 to lower the concns. of N2 to a set level or less.

摘要： PURPOSE:To convert hydrogen stored in a suction storage layer into hydrogen gas with high purity by introducing the material hydrogen gas into the apparatus via a water introducing pipe, and by releasing part of this material hydrogen gas being introduced out from a leadout pipe. CONSTITUTION:Hydrogen gas is introduced into the apparatus 1 from a hydrogen source by opening an opening/closing valve 8 on a lead-in pipe 2, and the material hydrogen gas is inhaled into a storage layer 4 through a filter 2a. At the same time, part of the material hydrogen gas being inhaled is released to outside the apparatus by opening an opening/closing valve 9 on a leadout pipe 3. Thus the specific amount of hydrogen gas is released to outside the system by opening said valve 9 so as to prevent accumulation of impurities in the system during storage, which will ensure that the hydogen inhaled in the storage layer through reaction of the material hydrogen gas with hydrogen-inclusive alloy is given a high purity.

摘要： PURPOSE:To prevent breakage and noise due to impingement between a cargo bed and a chassis frame, by locking a rod in a hoist cylinder for rising the cago bed to a damper mechanism provided on a support plate for the cargo bed before the tilted bed is abutted against the chassis frame. CONSTITUTION:When a rod 2a having a top end pivotally attached to lift plates 3 through a cross-head 4 is extended by actuating a hoist cylinder 2 which is pivotally attached at its base end to a chassis frame, a tension force is effected in a tension rod 6 which is pivotally attached at its base end to the chassis frame and also pivotally attached to its top end to the above-mentioned lift plates 3 through a coupling shaft 7. With this arrangement the compression force of the hoist cylinder 2 acts to rotate and rise up a cargo bed pivotally attached to the rear end of the chassis frame. In this stage, the rod 2A is fitted into an engaging and releasing groove 9a in a damper member 9 constituting a damper mechanism 8 provided to the coupling shaft 7 before the cargo bed abuts against the rear end of the chassis frame, so that the cargo bed is secured at the maximum angle position.

Aq. soln. of a V compd. is added to the obtd. powdery ternary oxide (TiO
2 .WO
2 .SiO
2 ); the mixture is kneaded and heated to evaporate water to prepare extrudable paste, which is extruded into an appropriate mold. The molded product is dried and calcined at 150W650°C in the air. The obtd. catalyst has high denitration activity and low oxidation activity for SO

摘要： PURPOSE:To obtain ethylene glycol containing little impurities in high concentration and high yield, by separating an aqueous solution of crude ethylene glycol discharged from a process for preparing ethylene oxide from ethylene by the column chromatography, and circulating the separated ethylene glycol in a low concentration through the column chromatographic step. CONSTITUTION:An aqueous solution of crude ethylene glycol discharged from a process for preparing ethylene oxide is directly or preferably concentrated in a suitable manner and fed from a pipe 6 to a chromatographic column 1 packed with a cation exchange resin 2, and then developed with water from a pipe 3 to divide and obtain a column eluate according to the composition thereof and purify the ethylene glycol. A waste liquor part containing organic acid and colored components in high concentrations and almost no ethylene glycol and a part containing ethylene glycol in a high concentration are separated respectively from the column eluate and taken out of the system. On the other hand, an ethylene glycol part in a low concentration is passed through a pipe 7 and circulated through the column chromatographic step to obtain the aimed aqueous solution of the ethylene glycol in a high concentration.

摘要： PURPOSE:To feed an aqueous solution containing the titled substance and feed the solution to a step before the dehydrating distillation for preparing the titled substance, by separating the aqueous solution discharged from a process for reacting ethylene with oxygen to prepare ethylene oxide by the chromatography with a cation exchange resin. CONSTITUTION:Ethylene oxide (EO) obtained by catalytically reacting ethylene with oxygen in the vapor phase is reacted with water to give a rection solution containing the titled substance (EG), which is then subjected to the dehydrating distillation to afford EG. In the process, an aqueous solution, containing EG, organic acid components and coloring components, and discharged from the process for preparing EO is concentrated suitably, and separated by the chromatography with a cation exchange resin as a carrier by using water as a developing agent to give an aqueous solution of EG with reduced contents of organic acid components and coloring components, which is then fed to a step before the dehydrating distillation. An aqueous solution of EG obtained by the chromatographic separation is preferably treated further with a cation exchange resin and anion exchange resin.

摘要： PURPOSE:To industrially, advantageously and efficiently obtain gaseous compd. contg. H2 gas by heating a gas mainly consisting of CH4 and steam at the heated boundary material separating an adjacent combustion room and passing through porous catalyst layer. CONSTITUTION:City gas is burnt with air using a burner 6 in the zone 2 to be heated and the combustion gas is passed down through pores in the porous heat radiator 4. At that time, its sensible heat is transferred to the radiator 4, its temp. is steeply lowered and then, the combustion gas is exhausted from the lower part. In this case, radiation of heat occurs upwards, that is, to the boundary material 3 impermeable to gas, and heat it. The raw material gases, CH4 and steam, flow down between a bell jar and a cylinder of circular part, turn at the material 3 and pass upwards through pores in the porous heat accep tor 5 carrying a catalyst. In that place, the raw material gases are exposed to high temp. in the presence of the catalyst, reacted to produce H2 and CO, and the produced gaseous mixture contg. H2 is taken out from the upper part.
