PURPOSE:To enable independent control of vapor-phase composition of zone groups and carry out continuous operation for a long period, by dividing the interior of a reactor for carrying out vapor phase-solid phase reaction into three or more zones and mounting plate paddles on a stirrer under specific condition. CONSTITUTION:A horizontal reactor, equipped with a cylindrical vessel 1 having the horizontal central axis, a stirrer 7 having a rotating shaft 5 arranged in agreement with the central axis, a feed port 10 for an object for stirring and a taking outlet 11 for the product placed at both ends of the vessel 1 and two or more partition walls 2, 2', and 2'', placed perpendicular to the rotating shaft 5 and having an opening part 6 at the bottom dividing the interior of the vessel 1 into three or more zones and capable of carrying out vapor phase-solid phase reaction. In the above-mentioned reactor, the stirrer 7 is constituted of plural sets of one or more plate paddles 4 mounted in the direction of the rotating shaft and particularly two sets of the paddles forming a pair with the partition walls placed therebetween satisfy formulas I-VI. The adjacent pair of the paddle sets satisfy formula VII and I1, I2, S1, S2 and W2 are mutually equal at the same time (I1 is the clearance between the inner wall and the paddle tips on the feed side; I2 is the clearance between the inner wall and the paddle tips on the taking out side). |
