When a solid catalyst has to be kept in suspension or when there are two liquid phases, as in the nitration of aromatics, for instance, an agitator is required. Agitation is also necessary to equalize the temperature in the reator and to keep it at the desired level by efficient hert exchange through a jacket or an internal coil. Consequently, the batch reactor is generally considered to be spatially uniform in composition and temperature. The composition changes with time, however,. Temperature sequencing may be favorable for the selectivity or for achieving complete conversion in a safe way.In pure batch operation the reactants are completely fed into the reator at the beginning. For better control of temperature this type of operation may not be advisable and the reactants may have to be added progressively to the contents of the vessel. The reactor is then said to operate in the semibatch mode. Or, a product maybe withdrawn, for instance, water in an esterification, to reach complete conversion of the reactants.Batch and semibatch reactors are most often used for low production capacities, where the cost of labor and dead time are only a small fraction of the unit cost of the product. They are generally ecountered in the area of special chemicals and polymers and in pharmaceuticals, in particular, in plants with a wide variety of products.Plug flow reatorPlug flow is a simplified and idealized picture of the motion of a fluid, whereby all the fluid elements move with a uniform velocity along parallel streamlines, this perfectly ordered flow is the only transport mechanism accounted for in the pluh flow reactor model.Perfectly mixed flow reatorThis reactor type is the opposite extreme from the plug flow reactor considered above. The essential feature is the assumption of complete uniformity of concentration and temperature throughout the reator, as contrasted with the assumption of no inter mixing of successive fluid elements entering a plug flow vessel. Therefore, in the perfectly mixed flow reactor, the conversion takes place at a unique concentration (and temperature) level which, of course, is also the concentration of the effluent. To approch this ideal mixing pattern, it is necessary that the feed be intimately mixed with the contents of the reactor in a time interval that is very small compared to the mean residence time of the fluid flowing through the vessel. Further discussion of deviations from these ideal flow patterns are given later.The stirred flow reactor is frequently chosen when temperature control is a critical aspect, as in the nitration of aromatic hydrocarbons or glycerin. The stirred flow reactor is also chosen when the conversion must take place at a constant composition, as in the copolymerization of butadiene and styrene, or when areaction between two phases has to be carried out, or when a catalyst must be kept in suspension as in the polymerization of ethylene with Ziegler catalyst, the hydrogenation of a-methylstyrene to cumene, and the air oxidation of cumene toacetone and phenol.Several alternate names have been used for what here is called the perfectly mixed flow reactor. One of the earlist was “continous stirred tank reactor”, or CSTR, which some have modified to “continous flow stirred tank reactor”, or CFSTR. Other names are “backmix reactor”, “mixed flow reactor”, and “ideal stirred tank reactor”. All of these terms appear in the literature and must be recognized.Fixed bed catalytic reactorsThe dicovery of solid catalysts and their application to chemical processes in the early years of this cencury has to a breakthrough of the chemical industry. Since then, this industry has diversified and grown in a spectacular way through the development of new or the rejuvenation of established processes, mostly based on the use of solid catalysta.The main part of these catalytic processes is carried out in a fluidized bed to enable the continuous regeneration of the catalyst, the major solid catalyzed processes of today’ chemical and petroleum refining industries use fixed bed catalytic reactors. Today’s fixed bed reactors are mainly large-capacity units. Such a spectacular rise in reactor capacity is evidently tied to the growing market demand, but its realization undoubtedly also reflects progress in both technological and fundamental areas, pressed by the booming construction activity of the world.Fluidized bedAlthough the fluidized bed technique was introduced as early as 1926, the real breakthrough of fluidized beds was associated with the catalytic cracking of gasoil into gasoline in 1942. before that, catalytic cracking was carried out in fixed bed reactors. Catalytic cracking deposits carbonaceous products in the catalyst, causing rapid deactivation of the latter. To maintain the production capacity, the coke had to be burned off. This regeneration required switching the reactor out of production. In order to eliminate the cycling, attempts were made to circulate the catalyst and burn off the coke in a separate vessel, the regenerator. One approach was to use a moving catalyst bed: in a very compact mass, into the regeneration. From the regenerator thecatalyst was returned to the top of the reactor by a bucket conveyor. Later, the convetor system was replaced by a gas lift. Finally, both the reactor and the regenerator were operated under transport conditions. The high velocities required for pneumatic transport caused considerable attrition of the catalyst. To lower the velocities, very fine solids had to be used. It was then found that the dense mixture of solids and gas behaved in many aspects like a fluid, and this makes the control of streams much more convenent. Since then, fluidized beds have been used in other fields where solids have to be bandled, such as the roasting of ores and in catalytic reactors for highly exothermic reactions. The latter application is based opun another advantage: the high turbulence created in the fluid-solid mixture leads to much higher heat transfer coefficients than those which can be obtained in fixed beds. Therefore, fluidized bed reactors have now also found use in exothermic processes requiring close temperature control such as the oxidation of naphthalene into phthalic anhydride, the ammoxidation of propylene into acrylonitrile, the oxychlorination of ethylene into ethylene dichloride-the first step of vinyl chloride manufacture, and the process for polymerization of ethylene. A new and important application is fluid bed combustion of coal, which permits using low-grade coals rich in mineral matter, less suited for conventional boilers. An additional advantage is the in situ capture of sulsur dioxide by means of injected limestone. Whereas in the above cases only a minor fraction of the catalyst is entrained with the gas, so that the major part is confined in dense bed, with a dilute section and cyclones above it. There are also processes in which the total amount of catalyst is entrained by the gas. The reactors then belong to the category of transport reators.。

以上是化工行业中常用的一些词汇和它们的含义。

这些词汇在化工生产和研发过程中经常会被提及，对于从事化工行业的人员来说，了解这些词汇的含义是非常重要的。

在化工行业中，不仅仅是常用词汇，还有许多专业术语和领域特定的名词。

下面将介绍一些例如催化剂、蒸馏和聚合物等专业术语：催化剂：催化剂通常是在化学反应中起催化作用的物质，它能够改变反应的速率而不被反应消耗。

在化工生产中，许多反应都需要催化剂来加速反应速率，从而提高生产效率。

常见的催化剂包括金属、金属氧化物、酶和复合材料等。

在催化剂的选择和设计中，需要考虑反应条件、催化剂的稳定性、成本和环境友好性等因素。

蒸馏：蒸馏是一种用于分离液体混合物的方法。

在蒸馏中，液体混合物首先被加热以产生蒸气，然后通过冷凝将蒸气凝结成液体，从而分离出不同组分。

蒸馏通常用于提纯化学品、分离混合物和回收溶剂。

在化工生产中，蒸馏是一项常见的分离技术，可以应用于石油化工、化学工程和生物工程等领域。

聚合物：聚合物是由多个单体分子通过共价键连接而成的大分子化合物。

聚合物在化工行业中有广泛的应用，包括塑料、橡胶、纤维和树脂等。

聚合物的性质取决于其结构、分子量和组分，可以通过化学合成或物理方法来获得所需的聚合物材料。
