Isobutane dehydrogenation market

2010-11-01View Original

Thread Content

There are already many industrial operations for propane dehydrogenation in China, but isobutane dehydrogenation has not yet been put into use there; it is said that Shandong Yuhuang plans to launch a 300,000-ton isobutane dehydrogenation project; Currently, UOP and Lummus technologies are mostly used for isobutane dehydrogenation abroad; is this technology available in China?

First of all, where are 300,000 tons of isobutane? It’s hard to find even 30,000 tons. Is there a way to import it? I’m also interested in knowing the product composition of isobutane dehydrogenation. Leaving the catalyst aside, what are the temperature and pressure conditions?

It’s true; the technology comes from the United States.

The last edit to this post was made by yangzy2008 on 2010-11-2 at 17:38; it’s around 600 degrees. The main issue is that high temperatures place high demands on the catalyst, resulting in a low conversion rate in each reaction step

Reaction temperature: 590 degrees, reaction under negative pressure

Where in China are there units for producing propylene via propane dehydrogenation?

No one has yet managed to carry out alkane dehydrogenation on a domestic scale

The supply of n-isobutane is no longer a problem domestically; the issue lies in its downstream processing and utilization.

After the aromatization process became popular, isobutane was in ample supply. . .

After separation, the aromatization product is best used as a feedstock for isobutane dehydrogenation.
