The research project on the 10,000-ton-scale fixed-bed technology for cobalt-based synthetic oil, supported by the Chinese Academy of Sciences and various enterprises, has made breakthrough progress after years of work. The industrial pilot test on a 10,000-ton scale was successful: the catalyst operated stably for 2,000 hours, with a CO conversion rate of 85% and a yield of C5+ above 85%. The side-line unit functioned properly, reaching an internationally leading level. On November 15, the High-Tech Bureau of the Chinese Academy of Sciences organized experts in Changzhi, Shanxi, to evaluate the scientific and technological achievements of a major research project funded by the Academy – namely, the fixed-bed technology for producing ten-thousand-ton quantities of cobalt-based synthetic oil, a project that was carried out jointly by our institute and Shanxi Lu’an Mining (Group) Co., Ltd. The experts present listened to the technical report on the work carried out by the project team, and inspected on-site the operation of the 10,000-ton industrial demonstration facility. After scrutiny and thorough discussion, it was unanimously agreed that: 1. This achievement focuses on **energy strategies and market demands, and has seen the development of cobalt-based Fischer-Tropsch synthesis fixed-bed technology as well as industrial trials aimed at large-scale commercialization. 2. Related to these achievements, **22 invention patents have been applied for or obtained**, forming a complete technical system. The first domestic industrial trial of coal-based syngas for cobalt-based synthetic oil (CTL) was carried out, with continuous operation lasting over 2,000 hours; this has laid a solid foundation for industrial demonstrations with a capacity of 50,000–100,000 tons per year, and significant economic and social benefits are expected to be achieved. Developing coal-based clean fuels is an important part of China’s alternative energy strategy; the Ministry of Science and Technology planned a major project during the 12th Five-Year Plan period titled “Key Technologies for Large-Scale Coal-Based Clean Fuels and Process Integration Technologies”. The achievement of this result will play a positive role in promoting the rapid development of coal-based clean fuel technology research and development at my institute during the 12th Five-Year Plan period. http://www.s*cc.ac.cn/xwzx/zhxw/201011/t20101124_3028437.html.

I’m numb after seeing such news – internationally leading? Please, if it’s companies that say such things, it’s understandable – they just don’t know and are talking nonsense. But does the Coal Chemistry Institute itself say such things as well? Let’s not even talk about Shell’s technology – surely those who have carried out pilot tests using cobalt-based fixed-bed systems around the world can be grouped together. Please allow me to exaggerate a bit, but after all these years working in this field at the Coal Chemistry Institute, one must be aware of the international developments in this technology. Such statements make me feel once again the impatience within China’s research community (I’ve been experiencing this lately quite often). As for international advancements, I can’t say a word about them. To claim international leadership based on such data – do they think the Earth is just Shanxi? “\"The first domestic industrial test of cobalt-based synthetic oil using coal-based syngas was completed.\" I suspect this isn’t the first domestic industrial test facility for cobalt-based fixed-bed processes using coal-based syngas, right?
Lay the foundation for a single industrial demonstration plant with a capacity of 50,000 to 100,000 tons per year? Is the starting point a bit low? It’s definitely aiming for million-ton-class industrial demonstrations!
Anyway, it’s good data; something to be pleased about； But whether it appears impetuous is something for future generations to judge!
What are the values of 85% CO conversion rate and an yield of over 85% for C5+? How were these figures obtained? Loop? What is the recycling rate?
Advancing the further industrialization of this technology is believed to be able to solve all the problems on the way forward, which is truly commendable!
