Methanation process
Thread Content
Isn’t it true that there are already some research institutions in China that have developed catalysts with good catalytic performance? What’s the specific situation? Is there anyone who knows and can provide relevant information? Given that, what are the advantages and disadvantages compared to foreign techniques such as those of Topso, David, and Ruchi?
Currently, in China, the catalyst manufacturers that are researching methanation catalysts and carrying out pilot-scale tests include the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, the Southwest Research Institute, Wuhan Colin, Nanjing Guochang Company, and others. Their biggest difference from foreign catalyst manufacturers is that the specifics of their actual industrial application are unknown
Let’s start with adiabatic reactors, which are the mainstream approach. In China, the actual temperature resistance is roughly around 500; it might be a bit higher, up to 550, but that’s due to marketing tactics, you know. Abroad, the claimed value might be 700, while the actual value is 650. Higher temperature resistance allows for higher CO concentrations and a larger processing capacity, and this is probably the most important factor. When it comes to actual applications or industrial use, there’s no comparison possible. The isothermal reactors produced by Hangzhou Linda in China have lower temperatures, which is an advantage, but they require many thin tubes in order to handle large volumes of material. . The process is complex and costly. It’s not easy; just like in the case of Fischer-Tropsch synthesized oil, that’s why there is currently a lot of research and development focused on slurry-bed reactors for Fischer-Tropsch processes. Linda just applies for patents everywhere. I have only known about this for three months; please correct me if there are any mistakes. .
