News on coal-based ethylene glycol
Thread Content
It is said that Jiangsu Danhua Group and Shanghai Pujing Chemical Technology Co., Ltd. have recently started collaborating on a project to produce ethylene glycol from coal-based syngas.
If anyone knows the specific details, please let me know. We are paying close attention to the developments regarding ethylene glycol; thank you in advance to all our friends for their support.
Reply to 2# Yong'er: What’s going on? How about probing the situation?
We started collaborating a long time ago; when did this news come out?
Reply to 4# shuishou: I have been considering a project involving ethylene glycol recently. It is said that both Danhua’s technology and Pujing’s technology are quite good. I wonder how the cooperation between these two companies is progressing? Have regeneration, carbonylation, hydrogenation, and purification all been done? It seems that there are no issues with the process now; the key lies in the hydrogenation catalyst. I hope all fellow sailors will provide more information~~
Reply 5# DHEG: The scaling capacity of the Danhua project is quite good.
What is the activity and lifespan of the hydrogenation catalyst? What about the reaction conditions? You know?
Danhua utilizes the technology from the Fujian Institute of Physical Chemistry, while Pujing collaborates with East China University of Science and Technology. How did these two companies end up working together? Please let those familiar with the situation know.

Just a few days ago, Danhua and Wu Zheng started working together; if things continue like this, won’t all those involved in the production of ethylene glycol from coal end up being part of the same group?
The progress of the 200,000-ton coal-based ethylene glycol production facility project is slower than expected; the main issue is the decline in catalyst stability in the process of producing ethylene glycol via oxalate hydrogenation, resulting in a production capacity of only 30%.
Reply to 9# han9th, Brother Han: I heard that Wu Zheng’s technology originated from Danhua – so why are they cooperating now? ? ?
