This company began research on coal high-pressure catalytic hydrogenation technology in the 1960s, and the related pilot plants were in operation from 1984 to 1991, during which a large amount of engineering data was accumulated. .

I hope to get an overview of all the technical aspects of this company, such as the processes used, the current stage of development (lab, pilot scale, or industrial production), and the technical features, with as much detail as possible. If you want to promote it, it is advisable to provide detailed explanations within the scope of confidentiality; otherwise, the credibility will be low. Also, I hope you remove your contact email; otherwise, posts like yours are considered advertisements and should be moved to the technical promotion section. Those who wish to get in touch with you can do so within the platform.
The full name of the EDL process is High-pressure catalytic hydrogenation of coal; it should be considered a technology for the direct liquefaction of coal. The company began research on coal high-pressure catalytic hydrogenation technology in the 1960s, and the related pilot plants were in operation from 1984 to 1991, during which a large amount of engineering data was accumulated. Between 1986 and 1989, two industrial plants with capacities of 95 t/d and 350 t/d were designed. The EDL process includes the following elements: • Coal preparation and slurrying • Reaction system with liquid-phase hydrogenation and recycle gas system • Vacuum flash distillation • Atmospheric distillation. It also involves various utility systems, such as an emergency expansion system, hydrogen production systems, steam and condensate systems, and process water systems.
Requirements for raw materials:
Coal: Ash content ~ 15 wt% (based on dry matter); Sand content ~ 1 wt% (based on dry matter); Salt content ~ 2 wt% in the ash.
Hydrogen: H2 ~ 92 vol%; CO ~ 10 ppmv; CO2 ~ 0.1 vol%.
The main process parameters are as follows:
• Yield: approximately 50–60% light/middle oil mixture along with cracked gas, without vacuum residue; or approximately 85% light/middle oil mixture along with cracked gas, including vacuum residue.
• Catalyst usage: 1.5–2% of the feed coal.
• H2 requirement: around 900–1100 Nm3 per ton of coal.
• Gas/product ratio: approximately 1300–1500 Nm3 per m3 of slurry.
Based on our experience, especially in the field of lignite hydrogenation, we can provide the following services:
• Analysis of coal quality and assessment of its hydrogenation potential.
• Preliminary investigation regarding the selection of appropriate equipment.
• Optimization of the main process steps.
• Technical evaluation of different process options.
• Planning for small-scale, continuously operating pilot plants to conduct preliminary tests.
• Preparation of feasibility studies.
• Site surveys.
• Basic engineering design for large-scale pilot plants, to establish the foundations for the actual production plants.
• Design of process stages for large-scale pilot plants with a capacity of approximately 25 kt/year of coal (on a daf basis), taking into account the requirements of major equipment and local conditions.
• Overall planning for production plants.
I think this provides enough detail!

If the technology is good, the Germans should develop an industrial setup on their own, rather than letting the Chinese carry out tests on large-scale investment projects.
The tone upstairs is very strange. Just because we have the technical capability to build industrial facilities, it doesn’t mean we necessarily have to build them ourselves. It’s like when you go to a supermarket to shop; there are many products, and you buy what meets your needs. You don’t need it; can’t you just not buy it? Such things must be mutual consent.
