We all know that the chemical industry is highly specialized. As an important part of the chemical industry, the design and development of refinery catalysts need to go through three stages before they can be produced quantitatively. What are the three stages?
(1) the exploration stage: according to the chemical reaction characteristics, consult the relevant literature analysis, theoretical guidance, from the technical and economic design and preliminary development. The catalyst was determined after determination, screening and improvement for further amplification. Note: this phase is usually performed in the laboratory. Generally, only the synthesis method and the activity and selectivity of the catalyst are evaluated. Laboratory experiments are usually carried out on small devices that reflect the intrinsic activity of the catalyst.
(2) analog amplifier stages: (1) phase catalyst in a certain number of, under the condition of industrial production, activity, selectivity, life, and then the productive performance inspection, such as improved and perfected, obtain comprehensive performance data of catalyst, proposed can be applied to the industrial production scale and the data for industrial production. Note: this stage is usually carried out on industrial installations of a certain scale (according to production conditions), and can be carried out in the amplification laboratory or on the lateral lines of industrial installations. At this stage, the law of reaction dynamics should also be studied to provide data and data for industrial amplification.
(3) industrial production stage: design and establish the reaction device and catalyst production workshop for industrial production, and officially carry out industrial production after trial run.
Catalyst manufacturers Sciensun chemical industry in particular pointed out that in each of the above stages, should pay attention to the economic feasibility, technical and economic comprehensive evaluation and analysis, otherwise the production is meaningless.
