Comparative discussion on the HPPO process
Thread Content
As we all know, there are currently three patent holders for the HPPO process: Evonik from Germany, BASF and Dow Chemical, as well as the technology developed by the Dalian Institute of Physical Chemistry. I would like to ask what the differences among these three are? What’s special about it? Experts, please give me some advice
I haven’t heard of any HPPO technology at Dalian University of Physical Chemistry. Are you referring to Xi Zuwei’s phase-transfer catalyst technology (tungsten-molybdenum catalyst series)? I don’t know what the prospects for the industry are. In China, the only place where HPPO (titanium-silicon molecular sieve system) has been put into industrial use is the Changling Refining and Chemical Complex, operated by the Chinese Academy of Sciences. In China, the main institutions working on this technology are Dalian University of Technology, East China University of Science and Technology, and us. They are all in the pilot stage and not yet in commercial operation.
Yes, the titanium-silica molecular sieve catalyst we use for ammonia oximation has been successfully industrialized in three enterprises in Shandong, Henan, and Hebei. I am currently working on the HPPO process and its titanium-silica molecular sieve catalysts.
It’s quite professional; one needs to have a good understanding of high school-level technology
There are many projects to be carried out domestically, but the specific details are not very clear
How is the project at Taixing Yida? Does anyone know anything about it?
Which company’s technology does Gimpo Kumho use? Does anyone know?
What are they doing? It might just be something said without any real meaning
