摘要： PURPOSE:To efficiently remove a sulfur compd. contained in a reducing gas, by calcining an adsorbent on which a sulfur compd. contained in a high-temp. reducing gas has been adsorbed and using the obtained regenerated gas for pressurizing air or oxygen for desorption. CONSTITUTION:A coal, a heavy oil, etc., 1 is fed into a gasifying oven 3 where it is partially burnt with a small amount of air or oxygen 2 to obtain a high- temp. reducing gas 4. Coarse particle dust 6 contained in the high-temp. reducing gas 4 is removed with a dust-collector 5, and a fine dust 8 is removed with a precision dust collector 7 to obtain a gas 9. The gas 9 is fed into an adsorption-regeneration apparatus 10 where the gas is brought into contact with an adsorbent to remove a sulfur compd., thereby obtaining a refined gas 11. Air and/or oxygen 17 is fed into a regeneration apparatus 10 through a compressor 16 to calcine the adsorbent. The obtained SO2 gas 12 is fed through a gas cooler 13 and a blower 14 into a gas expander 20 to expand the gas.

摘要： PURPOSE:To stabilize the concns. of CO and H2, by absorbing a S-compound with an absorbent based on metal oxide and regenerating said absorbent by O2-gas and subsequently reducing the absorbent until the concn. of reducing gas before absorption becomes same to that after absorption and repeating this operation. CONSTITUTION:Gas 1 based on H2 and CO from a gasifying process receives dust removal treatment and is flowed to an absorbing regeneration tower 6 packed with an absorbent 9 comprising oxide of a metal such as Fe, Zn, Mo, Mn, Cu or W to remove a S-compound. O2-containing gas 2 is passed through an absorbing regeneration tower 7 to regenerate the absorbent and SO2-gas 5 is obtained. Further, part of the gas from the gasifying process is flowed to an absorbing tower 8 to reduce the absorbent until the concns. of H2 and CO in the purified gas 3 become constant and the treated gas is returned to the gas 1 of the gasifying process through a valve 24. These processes are successively changed over to stabilize the concns. of H2 and CO and the purified gas is continuously supplied.

摘要： PURPOSE: To remove metals (Na, Ti, etc.) contained in coal efficiently, by treating finely ground coal with hot water and separating the water and the coal using two or more centrifugal separators operated alternately.
CONSTITUTION: Coal is ground to a particle diameter of 0.25mm or less at a grinding stage 1 and is then mixed with water 9 in an amount by weight more than 3 times that of the ground coal at a mixing stage 2. The obtained slurry is treated at an extraction stage 3 at 100°C or above for at least 10min to undergo demetallization, and then cooled to 100°C or below at a cooling stage 4. This cooled slurry is conveyed through line 13 to a separation stage 5, where it is centrifuged (under at least about 10G) using a centrifugal separator with a filter cloth to collect the demetallized coal, and the water 15 containing extracted metals is discharged. Along with the separation stage 5 above-mentioned, a similar separation stage 6 is established where the separation is carried out alternately, switching from each other at specified operating intervals.

摘要： PURPOSE: To improve a regeneration effect considerably and to prolong the life of a catalyst in spite of repeated use by washing the catalyst for contact reduction and denitration of ammonia of which the performance is decreased by treatment of the waste combustion gas in an ultrasonic atmosphere.
CONSTITUTION: A catalyst for contact reduction and denitration of ammonia of which the catalyst performance is decreased by the treatment of the waste combustion gas such as waste gas of a boiler is wsahed in an ultrasonic atmosphere to regenerate the activity of the catalyst. The waste combustion gas contg. dust contains SO
x usually, and if resistance to SO
x is considered, TiO
2 , ZrO
2 , etc. are more preferable than Al
2 O
3 for the catalyst carrier to be used for said waste gas. An ultrasonic wave is used in this method; therefore, not only the water soluble alkaline component but also the fine dust clogged in the fine holes of the catalyst are removed by the cavitation effect thereof.
