For hydrogenation reduction projects with a large scale of production where the raw materials tend to vaporize, the use of fluidized bed reactors is more economical; in particular, since this fluidized bed employs a silica gel-copper catalyst, it can **reduce production costs**. The advantages of fluidized bed reactors are: ① It enables continuous input and output of solid materials ； ②The movement of fluids and particles enables the bed to exhibit good heat transfer properties, results in a uniform temperature within the bed, and makes it easy to control; it is particularly suitable for exothermic reactions ； ③The contact area between them is large, resulting in a fast reaction rate ； ④It facilitates the continuous regeneration and recycling of catalysts. The fluidized-bed hydrogenation unit designed by LEBEL Chemical features a bed that is fully fluidized, exhibiting properties similar to those of a liquid. Fluids with a density lower than the average density of the bed can remain suspended on the bed surface ； Keep the bed surface level ； The gas flow is uniform, the catalyst consumption per unit of product is low, the nitro content is minimal, and the product quality is high. It operates in a fully automatic continuous manner, and it can generate a certain amount of low-pressure steam for reuse by the enterprise, making it economically viable. Lebel Chemical has successively built plants with an annual production capacity of 2,000 tons and 10,000 tons for the hydrogenation of monomers to produce p-toluidine, o-toluidine, etc., all of which are operating well.
