Catalyst loading in a tubular fixed-bed reactor
Thread Content
A tubular fixed-bed reactor has a large number of reaction tubes. How should the catalyst be loaded in order to ensure fast loading, as well as uniform distribution of the catalyst within each tube? After loading, the pressure drop across each tube should be the same and their heights should be consistent.
Usually, a professional loading company is hired to ensure quality, under the guidance of the catalyst manufacturer.
The loading of catalysts in tubular fixed-bed reactors is generally carried out by specialized catalyst loading companies. During the loading process, it is particularly important to control the bulk density (referred to as bulk ratio by many companies in China), and efforts should be made to ensure that the bulk density remains roughly constant from top to bottom within the reaction tube. After loading is complete, it is necessary to ensure that the pressure drop across each reaction tube is roughly the same. Generally, the reaction tubes are not filled to capacity during loading; a certain amount of headspace is left to facilitate the addition of a small amount of catalyst when balancing the pressure drops between the various reaction tubes. At the end of loading, in order to balance the pressure drop in the reaction tubes, the amount of catalyst and the loading height within each reaction tube will vary slightly. Commercial tubular fixed-bed reactors mostly use mechanical charging, which allows for a fast loading speed. In the case of small-scale reactors, manual loading is used, but it’s very slow. Last time, we had four reactors in total, with 24 reaction tubes in all, and two Dutch people spent 2 days doing the loading work, without including the time required for preparatory tasks such as sandblasting.

How many hours is the typical lifespan of a catalyst? It seems quite troublesome to load the catalyst into a tubular reactor
Who has the contact information of manufacturers that install fixed-bed catalysts?
Jiangsu Tianpeng is very professional, but it doesn’t cooperate with smaller companies
There are many of them, such as Shandong Henghui, Shanghai Yangshen, Jiangsu Tianpeng, and so on. Let’s take a look at your specific needs and requirements.
Shanghai Yangshen is probably the best at it
