摘要： A process for producing alkali pulp by using a single, cylindrical pressurized reaction vessel having therein a liquor-inpregnating zone, a cooking zone, a washing zone, and a diluting zone in that order, and having a motor-driven scraping or agitating device and a pulp discharging outlet in the end portion of the diluting zone. Alkaline aqueous medium containing dissolved oxygen therein is introduced into the diluting zone. A part of the introduced alkaline aqueous medium countercurrently contacts cooked cellulosic materials transferred from the washing zone to the diluting zone to proceed with oxygen-alkali delignification, and is finally discharged out of the vessel from the end portion of the cooking zone. The remainder of the introduced alkaline aqueous medium contacts the cooked cellulosic materials in the diluting zone in a scraping or agitating manner by means of the motor-driven scraping or agitating device to proceed with oxygen-alkali delignification, and finally serves as diluting liquor to be discharged out of the vessel accompanying the resulting pulp.

摘要： Hydrocarbon is catalytically converted by using a fluorine compound represented by the general formula Z.sup.+ MF.sub.6.sup.-, wherein Z is a hydrogen atom or a hydrogen group, and M is a niobium atom, an antimony atom or a tantalum atom as a catalyst, wherein a catalytically inactive component is settled as a heavy liquid phase or deposited as a solid in a reaction product solution from the conversion of hydrocarbon, the heavy liquid phase or the solid is removed from the reaction product solution, thereby removing substantially the catalytically inactive component therefrom, and the remaining catalytically active component is reused in the conversion of hydrocarbon. An amount of a fresh catalyst solution to be supplemented is considerably reduced by effectively reusing the catalytically active component.
