Abstract: The present invention discloses a catalyst for paraffin isomerization, as well as a preparation method and use thereof. The catalyst comprises a TON molecular sieve modified by rare earth, an inorganic refractory oxide modified by zirconium oxide and a noble metal of group VIII. The weight ratio of the TON molecular sieve modified by rare earth to the inorganic refractory oxides modified by zirconium oxide is 10:90 to 90:10, and the content of the metal of group VIII is 0.1 to 10 wt % based on the metal. When used in the process of isomerization dewaxing of various raw materials containing paraffins, the catalyst can not only decrease the solidifying points of raw oil containing paraffins, but also increase the yield of liquid products. Particularly, when used in the process of isomerization dewaxing of lubricating oil distillates, the catalyst is advantageous in producing base oil for lubricating oil with a high a higher yield, a lower pour point (solidifying point) and a higher viscosity index.

Abstract: A sheet feeding device includes a sheet placement portion, a regulating portion, and an output portion. The regulating portion includes a first regulating portion and a second regulating portion. At least one of the first regulating portion and the second regulating portion can move in the width direction. The output portion includes a first output portion that extends from the first regulating portion toward the second regulating portion, and a second output portion that extends from the second regulating portion toward the first regulating portion. The first output portion includes a first end portion. The second output portion includes a second end portion. In a proximity state, the first end portion is located closer to the second regulating portion than the second end portion. The proximity state is a state in which a distance between the first regulating portion and the second regulating portion is at a minimum.
