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 Or, a product maybe withdrawn, for instance, water in an esterification, to reach complete conversion of the reactants.Batch and semibatch reactors are most often used for low production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.。

化工相关词汇化工相关词汇化工是指利用化学反应和物理变化等手段对自然界中的化学物质进行分离、提纯、合成和加工等技术过程的总称。

从广义上讲，化工涵盖了从研发原料到制造产品再到销售和应用的全过程。

而对于从业者来说，掌握化工相关词汇是非常重要的。

下面是一些常见的化工相关词汇：1. 反应器（reactor）反应器是化学反应过程中的核心设备，通常是一个密封式容器，用于实现反应的控制和运行。

反应器通常是由钢铁、钛、镍、不锈钢等材料制成的。

2. 反应物（reactant）指参与化学反应的原始物质，只有反应物发生化学反应才能形成化学反应物。

3. 反应性（reactivity）反应性是衡量物质与其他物质反应速率或化学变化易度的性质。

物质的反应性可通过其最初的化学组成，以及其中不同部分之间相互作用和分子间交互作用来体现。

4. 催化剂（catalyst）催化剂是指在化学反应中能够降低反应活化能、提高反应速率、同时不改变化学反应过程对末产品的影响的物质。

催化剂可以分为化学催化剂、生物催化剂和光催化剂，广泛应用于各种化学反应和工业流程中。

5. 电解质（electrolyte）电解质是化学中的一种重要物质，指在水或其他溶剂中能够离解成离子的物质。

电解质常用于电沉积、制取金属、电池、电解和阴极保护。

6. 化学反应（chemical reaction）化学反应是指两个或更多物质之间发生的化学变化，产生新的物质的过程。

化学反应通常需要化学反应物、催化剂、温度和反应过程中产生的能量。

7. 化学工程（chemical engineering）化学工程是一门基于化学原理和技术，利用化学反应原理和设备制造技术开发、设计、生产和优化生产过程的工程学科。

8. 材料科学（materials science）材料科学是研究材料的物理、化学的性质、加工、制备以及材料性能与结构之间相互关系的学科，涉及从微观到宏观层面的材料研究。

9. 加工工艺（processing technology）加工工艺是指制造过程中使用的技术、方法、步骤和设备。
