    • In the reaction of catalytic gas phase oxidation by means of a shell-and-tube type reactor adapted to circulate a heating medium to the shell of the reactor through the medium of a circulation device connecting an annular conduit connected thereto, a method for the catalytic gas phase oxidation characterized by subjecting a part of the heating medium extracted from the shell of the reactor to heat exchange, introducing the heating medium resulting from the heat exchange into the proximity of a heating medium circulation inlet on the inlet side of the circulation device or the annular conduit on the outlet side of the reactor. The flow rate of the heating medium after the heat exchange is preferred to be in the range of 2-40 vol. % based on the flow rate of the heating medium within the shell of the reactor and the temperature difference of the heating medium at the inlet and the outlet to be in the range of 15-150° C. According to this invention, it is made possible to reduce evenly the hot spots in the reaction tubes, improve the yield of the product aimed at, and implement a reaction of catalytic gas phase oxidation of propylene or isobutylene.
    • 在通过壳管式反应器进行催化气相氧化的反应中,该反应器适于通过连接连接其的环形导管的循环装置的介质将加热介质循环到反应器的壳体,催化剂的方法 气相氧化特征在于使从反应器壳体中提取的一部分加热介质进行热交换,将由热交换产生的加热介质引入循环装置入口侧的加热介质循环入口附近,或 反应器出口侧的环形导管。 热交换后的加热介质的流量优选为2-40体积%。 基于反应器壳体内的加热介质的流量,入口和出口处的加热介质的温度差在15-150℃的范围内。根据本发明,制成 可能均匀地减少反应管中的热点,提高目标产品的产率,并实现丙烯或异丁烯的催化气相氧化反应。

    • An image forming apparatus includes an apparatus body, a recording head, a head tank, a displacement member, an air release unit, a main tank, a liquid feed device, a body-side detector, and a supply controller. The supply controller controls a normal filling operation to start feeding liquid from the main tank to the head tank without opening the air release unit when a consumption amount of the liquid in the head tank is a threshold amount or greater, and stop feeding the liquid from the main tank to the head tank when the body-side detector detects an arrival of the displacement member at a normal fill position. When the body-side detector detects the displacement member at a start of the normal filling operation, the supply controller corrects the normal fill position to a position at which the liquid feed device can feed the liquid to the head tank.
