    • Processes for the continuous production of aromatic carboxylic acids by reaction of nitric acid with an aromatic compound having an oxidizable alkyl or alkoxyalkyl substitutent which comprise mixing the aromatic compound in the form of small droplets with a large volume of dilute nitric acid having a concentration between 2 and 14% by weight of nitric acid that is maintained at a superatmospheric pressure between 15 and 80 atmospheres and at a temperature between 160.degree. and 230.degree.C, which processes comprise continuously passing a reaction mixture consisting of the aromatic compound and the dilute nitric acid through a series of at least three consecutively arranged vertical reactor column in each of which the ratio of the weight of the reaction mixture containing the dilute nitric acid to the weight of the aromatic compound is continuously maintained at at least 50:1, the nitric acid concentration in each of the reactor column being continuously maintained at an originally preselected concentration by the addition of amounts of more-concentrated nitric acid while aliquot portions of the aromatic compound based upon the number of vertical reactor columns in the series are continuously introduced into each of the reactor columns, the reaction zones each being maintained at an optimal oxidation temperature between 160 and 230.degree.C for the aromatic compound that is being oxidized, and continuously passing the reaction mixture into a final reactor column that is maintained at a higher temperature than the preceding series of reactor columns, and continuously discharging the reaction mixture containing between 10 and 20% by weight of the aromatic carboxylic acid thus produced from the final reactor column.

    • The reactor has a reactor chamber bounded by a peripheral wall, and the reactor chamber is subdivided by an upright partition wall into an inlet chamber and an outlet chamber. The partition wall extends transversely of the chamber and has free ends each of which is spaced from a juxtaposed portion of the peripheral wall by a distance equal to between substantially 10-30% of the cross-sectional dimension of the reactor chamber in a plane connecting these juxtaposed wall portions. The partition wall is laterally offset by between substantially 10 - 30% of the diameter of the chamber in the direction of offset so that the inlet chamber is larger than the outlet chamber. An inlet communicates with the inlet chamber to admit into the same carbon particles which require reactivation and has an opening having a cross-sectional area equal to between substantially 5 - 25% of the surface area of a bottom wall bounding said reactor chamber, and an outlet which communicates with the outlet chamber to remove activated carbon particles from the same, the particles from the inlet chamber being composed to pass through the gap between the free ends of the partition wall and the circumferential wall to reach the outlet chamber.
    • 反应器具有由周壁限定的反应室,并且反应器室由直立分隔壁细分成入口室和出口室。 分隔壁横向延伸,并且具有自由端,每个端部与外围壁的并列部分间隔开等于连接平面的反应室的横截面尺寸的大致10-30%之间的距离 这些并列的壁部分。 分隔壁在偏移方向上横向偏离室的直径的大约10-30%,使得入口室大于出口室。 入口与入口室连通以进入需要再活化的相同的碳颗粒,并具有开口,该开口的横截面积等于界定在所述反应室的底壁的表面积的大致5-25%之间, 出口与出口室连通以从其中除去活性炭颗粒,来自入口室的颗粒组成通过分隔壁的自由端和周壁之间的间隙以到达出口室。
