Selection of reaction feedstock
Thread Content
What is the basis for choosing a reactor with feed at the bottom or at the top?
I didn’t notice that there was feeding at the lower part~~~
Regarding this issue of whether to start from the bottom or the top, it depends on the flow pattern of the catalyst inside the reactor. Hydrogenation is mostly carried out in fixed-bed reactors, where the material flows from top to bottom, while in bubbling beds it is the opposite.
This is the selection of process packages; each process has a specific reaction mechanism. The selection of a process package should be based on several key factors, including the properties of the raw materials, the requirements for product quality, the process technologies available in the industry, and the investment costs
Fixed-bed, fluidized-bed, and bubbling-bed reactors each have their own advantages, disadvantages, and applicable ranges; likewise, different process packages also have their respective suitable applications. The process and process package to be chosen should be determined based on the user’s raw material requirements and product specifications.
Both of our sections are fixed-bed reactors; one is of the bubbling type, and the other is a radial bed.
Is this related to the gas phase or the liquid phase? In the first stage, feeding is at the bottom of the liquid phase, while in the second stage, feeding is at the top of the gas phase.
