Which research institute’s technology is used for the tar hydrogenation process in Huadian’s 2*6 million tons/year lignite pyrolysis cogeneration project?

As the title says. [Quote] On May 30, the Huadian 2*6 million tons/year lignite pyrolysis cogeneration project officially commenced construction. This project is the first innovative coal chemical project undertaken by HuanDian – it constitutes the initial phase of the HuanDian Hulunbuir Large-Scale Integrated Energy Project. With a total investment of 7.9 billion yuan, it uses Hulunbuir lignite as raw material and employs independently developed technologies such as circulating fluidized bed co-production technology, lignite drying and shaping technology, and tar hydrogenation technology to jointly produce various products including high-calorific-value clean coal, diesel with a low freezing point, naphtha, and liquefied natural gas, thereby enabling the systematic utilization of lignite with high moisture content.
Let’s talk about it while driving. . . Improving the quality of lignite seems simple, but it involves considerable technical challenges in practice. Shenhua has encountered many difficulties in upgrading its lignite. Where does the hydrogen used in tar hydrogenation come from? I’d like to ask.
A circulating fluidized bed is much more flexible to operate than a fixed-bed reactor. I wonder if there is a circulation pump at the bottom of the reactor? The circulation pump is equivalent to the hydrogen circulation machine in the fixed-bed process, and it is very important
Reply 2# markhome: Is it from the Beijing Coal Research Institute?
Reply 3# kelvinlu: As the tar produced as a by-product of pyrolysis, the hydrogen source comes from the concentration and conversion of the raw coal gas generated as a by-product of pyrolysis
I have been keeping an eye on Huadian’s 2*6 million tons/year lignite pyrolysis cogeneration project. Design work was tendered in March, and supervision work was tendered in July; it’s just not clear which company will win the contract The winning bid announcement wasn’t found?
At that time, I talked for a long time with the Coal Science Research Institute; they admitted that the technology was good, but there was no demonstration available. Later it was said that Shengbang’s technology would be used, but it’s not clear what was actually used in the end
Quality improvement is from Shandong, with fluidized bed technology!
Hydrogen is produced from gas!
The technology used in Huadian Hulunbuir lignite pyrolysis cogeneration project includes: German ZEMAG technology for lignite drying and shaping, the fluidized-bed low-temperature pyrolysis technology from Zhejiang University, and tar hydrogenation technology provided by Shaanxi Coal Industry Shanghai Shengbang.
