    • Heterogeneous catalytic reactions are carried out continuously in liquid phase. To this end, a suspension of liquid starting material and particulate catalyst together with resulting reaction product is continuously conveyed upwardly in a reaction zone by the introduction, in accordance with the principle of an air-lift pump, of a gas near the bottom of the reaction zone, and recycled downwardly through a reflux line to the bottom of the reaction zone, the path of liquid material through the reflux line being interrupted by an injector system situated in a closed catalyst-separating zone containing recycle liquid; following establishment of the reaction equilibrium, starting material is continuously supplied to the reaction zone and crude, catalystfree recycle liquid is continuously removed near the head of the catalyst-separating zone, and recycle liquid which is to be removed is caused to travel through the catalyst-separating zone with the injector system therein towards the recycle liquid outlet at a velocity smaller than the sedimentation velocity of the catalyst under the operational conditions prevailing. More particularly, 1,4-dichlorobutene-2 is isomerized to 3,4dichlorobutene-1. To achieve this the reaction zone is supplied continuously with 1,4-dichlorobutene-2 or with a commercial mixture of 3,4-dichlorobutene-1 and 1,4-dichlorobutene-2; an inert gas is introduced into the bottom portion of said reaction zone; liquid material is heated to boiling therein; 3,4dichlorobutene-1 is distilled off near the head of said reaction zone; 3,4-dichlorobutene-1 is conveyed to a distilling zone and fractionated therein until pure; pure 3,4-dichlorobutene-1 is condensed in a cooling zone; and 1,4-dichlorobutene-2 having high-boiling fractions enriched therein is isolated near the head of the separating zone.
    • 非均相催化反应在液相中连续进行。 为此,将液体原料和颗粒催化剂与所得反应产物一起悬浮在反应区中,通过根据空气提升泵的原理引入靠近底部的气体而连续输送 反应区,并通过回流管线向下循环到反应区的底部,液体材料通过回流管线的路径被位于包含再循环液体的封闭催化剂分离区域中的喷射器系统中断; 在反应平衡建立之后,将原料连续地供应到反应区,并在催化剂分离区的头部附近连续除去粗的无催化剂的再循环液体,并将要除去的再循环液体通过 其中注射器系统的催化剂分离区以其在主要操作条件下的催化剂的沉降速度小于再循环液体出口。

    • A roller-lock is used as a sealing system for the inlet and outlet of material webs into or out of autoclaves and consists of a series of individual pressure chambers which are separated or defined by pairs of rollers whereby, the material passing from the atmosphere into the the pressure chamber of the autoclave moves through several staged pressure chambers having increasing pressure therein. When the material passes out of the autoclave it moves through the same chambers in an opposite direction to be subjected to staged decreasing pressure as it passes out of the sealing system.
