摘要： PURPOSE:To stably purify the titled gas without decreasing fuel source, by regenerating an adsorbent containing adsorbed sulfur compound with an oxygen-containing gas, reducing the adsorbent with a part of a high-temperature reducing gas and removing sulfur compound in the high-temperature reducing gas using the adsorbent. CONSTITUTION:A high-temperature reducing gas 1 partially burnt and gasified in a gasification furnace is introduced through a change-over valve 10 into an adsorption column 6 which is a first reactor filled with an adsorbent 9. After removing sulfur compound in the reducing gas by the above treatment, the pressure of the gas is reduced using a gas vent and the gas is passed through a gas cooler 31 and stored in a gas holder 33. An oxygen-containing gas 2 is introduced through a valve 16 into the reducing gas to a prescribed pressure to regenerate the adsorbent 9. The high- temperature regenerated gas left in a reactor is extracted under reduced pressure and a part of the high-temperature reducing gas is introduced through a valve 13 into the reactor to a prescribed pressure to reduce the adsorbent and reuse the adsorbent for the adsorption of sulfur compound. The high-temperature reducing gas 1 can be continuously refined to obtain refined gas 3 by successively performing the adsorption, regeneration and reduction in the 1st-3rd reactors 6, 7, 8.

In the operation, the adsorbent 2 consisting of a great number of tubular structures is set in such a way that adsorbing faces are made in parallel with the gas flow 3, and regeneration is carried out by making an oxygen-containing gas flow in the adverse direction to that during adsorption. EFFECT:This device is economically advantageous.

摘要： PURPOSE: To prepare a calcined titanium oxide, having a large surface area, improved strength and heat resistance, and suitable for a catalyst or catalytic carrier, by adding a fine particulate silicic acid to titanium sulfate, hydrolyzing the titanium sulfate heating, and drying and calcining the hydrolysis product.
CONSTITUTION: A fine particulate silicic acid is added to hydrolyze titanium sulfate under heating, and the resultant hydrolysis product is then dried and calcined to prepare calcined titanium oxide. In the method, the titanium sulfate is hydrolyzed under heating preferably in the presence of a fine particulate silicic acid to produce metatitanic acid, which is then converted into a sol. The resultant sol is filtered, dried and calcined. The presence of the fine particulate silicic acid suppresses the crystal growth of the titanium oxide in calcination, and the ungrown anatase type crystals remain. Thus, the aimed calcined titanium oxide having a large surface area and improved mechanical strength and heat resistance is obtained. The resultant product is suitably used as a catalytic carier or directly as a catalyst.

摘要： PURPOSE: To obtain a catalyst which can effectively accelerate denitration reaction and oxidation reaction of SO
2 simultaneously for treating waste gas, by allowing Fe
2 (SO
4 )
3 to be carried on a V
2 O
5 -TiO
2 catalyst.
CONSTITUTION: This catalyst is composed of 3W10wt% V
2 O
5 , 0.5W5% Fe
2 (SO
4 )
3 , and the rest of TiO
2 . This catalyst is obtained by impregnating and carrying aqueous FeSO
4 .7H
2 O solution to a catalyst which is formed by adding V
2 O
5 to a TiO
2 carrier manufactured from titanium hydroxide and by heating and drying the product. The Fe
2 (SO
4 )
3 contained in the above-mentioned amount accelerates SO
2 → SO
3 conversion reaction without reducing the denitration reaction so much. In this way, Nox contained in waste gases of boilers can be removed and, at the same time, dust, such as fly ash, etc., can also be removed efficiently. Moreover, when Fe(III) is used from the first time for allowing to contain Fe
2 (SO
4 )
3 , the denitrating capacity is remarkably retarded.

摘要翻译：目的：通过使Fe2（SO4）3载带在V2O5-TiO2催化剂上，获得可以有效加速SO2脱硝反应和氧化反应的催化剂，用于处理废气。构成：该催化剂由3-10wt％V2O5,0.5-5％Fe2（SO4）3和其余TiO2组成。该催化剂通过将FeSO 4·7H 2 O水溶液浸渍并携载到通过将V 2 O 5加入到由氢氧化钛制造的TiO 2载体中并通过加热和干燥产物而形成的催化剂而获得。上述量中所含的Fe 2（SO 4）3加剧了SO 2 SO 3转化反应，而不会使脱硝反应减少。以这种方式，可以除去锅炉废气中所含的Nox，同时可以有效地除去粉尘，如飞灰等。此外，当第一次使用Fe（III）以允许含有Fe 2（SO 4）3时，脱硝能力显着延迟。
