摘要： PURPOSE:To provide a means for activating simply an adsorbent without requir ing a heating facilities in a pressure swing adsorption apparatus. CONSTITUTION:In a method wherein a hydrocarbon gas is cracked by means of a synthetic gas manufacturing facility and CO gas is separated and recovered from the cracking gas by means of a pressure swing adsoption method, a non- oxidative circulation gas at starting-up time of the synthetic gas manufacturing facility is circulated in the following pressure swing adsorption apparatus. A special apparatus is not necessary and the circulation gas of the synthetic gas manufacturing facility itself can be utilized and a special heating facility is not necessary either.

摘要： PURPOSE:To increase the recovery rate of high-purity carbon monoxide by separating carbon dioxide, methane and moisture of cracked gas from other components prior to a process to separate and refine high-purity carbon monoxide, and recycling the obtained CO2-rich gas before a cracked gas generation process. CONSTITUTION:A cracked gas generated in a cracked gas generation process 1 is supplied to a pretreatment process 2, and carbon dioxide, methane and moisture in the supplied cracked gas are removed. Then, said gas is sent to a high-purity carbon monoxide separation/refining process 3. At the high-purity carbon monoxide separation/refining process 3, only carbon monoxide is allowed to pass through adsorption towers filled with adsorbent which adsorbs carbon monoxide selectively and separately from other components such as hydrogen, carbon dioxide, methane and nitrogen. Thus, the separation/refining process of carbon monoxide based on a pressure swing adsorption method takes place. After that, CO2-rich gas (c) containing methane and moisture with carbon dioxide as a main component removed in the pretreatment process 2 is recycled as a raw material.

摘要： PURPOSE:To separate and purify useful gas at a high recovery rate by packing the lower part of an adsorption tower with an adsorbent hardly causing powdering and the upper part with an adsorbent having high adsorbing ability and successively passing the useful gas through the adsorbent in the lower part and the adsorbent in the upper part. CONSTITUTION:When useful gas such as CO is separated from raw gas such as converter gas by a pressure swing adsorption method, the lower part of an adsorption tower 1 is packed with an adsorbent B hardly causing powdering, the upper part with an adsorbent A having high adsorbing ability and the useful gas is successively passed through the adsorbents B, A. These adsorbents may be silica gel or activated carbon supporting copper chloride and the adsorbent hardly causing powdering and the adsorbent having high adsorbing ability are separately produced by regulating calcining temp., etc. The useful gas such as CO can be separated and purified at a high recovery rate.

摘要： PURPOSE:To attain efficient purge with a small amt. of purge gas by carrying out purge with gas for desorbing adsorbed useful gas at a high flow rate in the early stage and at a low flow rate in the last stage. CONSTITUTION:Raw gas contg. useful gas such as CO is introduced into an adsorption tower 1 packed with activated carbon supporting copper (I) chloride, etc., and CO is selectively adsorbed. When this adsorbed CO is directly desorbed, gaseous impurities such as CO2 and N2 remaining in the tower 1 are discharged together with the CO and the purity of the CO is lowered. In order to prevent the lowering of the purity, part of the gaseous product is fed into the tower 1 as purge gas to purge the gaseous impurities before desorption. The flow rate of the purge gas is increased in the early stage and reduced in the last stage. Efficient purge is attained with a small amt. of the purge gas and high purity gas can be recovered at a high rate of recovery.

The tower 3 is then evacuated by a vacuum pump 4, a valve 5 is opened under vacuum suction and purge gas 6 is introduced into the tower 3 to regenerate the adsorbent. This adsorbent can be effectively regenerated with a small amt. of the purge gas and a significant economical effect is produced.

摘要： PURPOSE:To minimize a process flow change by separating the waste gas to be introduced into a reducing gas recirculating system to two systems,introducing the system having the higher reduction power to the lower part of a reducing zone and introducing the system having the lower reduction power to the intermediate part of the reducing zone. CONSTITUTION:The waste gas taken out of the top of the vertical reduction furnace 1 is subjected to cooling, dust removal and dehumidification by a cooling and scrubbing device 5 and is increased in pressure by a booster 6 through a piping 20. About 20% of the waste gas passing through the piping 20 is used as fuel for a reducing gas generator 4. About 70% of the gas increased in pressure is fed on an acidic gas removing device 7 where CO2, H2S, etc. are removed from the gas. The gas increased in the reduction power is heated up to the required temp. by a gas heater 8 and enters a piping 21 from which the gas is joined with the reducing gas generated in the generator 4 and is blown through a main reducing gas inlet 10 into the furnace 1. About 30% of the gas increased in pressure is heated by the heater 8 and is made into the preliminary reducing gas which is blown through a preliminary reducing gas inlet 9 into the furnace 1.
