      다국어 초록 (Multilingual Abstract)

      A simplified procedure is proposed for the desulfurization by means of the catalytic reaction of alkali-ferrite. The vapor of gas oil shall be passed over the catalyst containing alkali-ferrite supported on an inert carrier such as aluminium oxide. The alkali in the ferrite is potassium oxide or sodium oxide. The reaction temperature of catalyst shall be modified between 300℃ and 450℃, and the pressure atmospheric, and the feed rate of gas oil is 50㎖/hr. The sulfur content of the feed gas oil is 1.09 %. As the result, the efficiency of desulfurization has been about 60%, and the best conditions for catalytic desulfurization were as follow: 1) Alkali in the catalyst … potassium oxide. 2) Ratio of alkali oxide to ferric oxide … 1/1 (molar). 3) Ratio of alkali-ferrite to alumina … 1/1(weight). 4) Temperature of catalyst in the reactor … 400-450℃ at atmospheric pressure.
