Time of Award: The polyoxymethylene dialkyl ether (DMMn) developed as part of this research is an oxygen-containing diesel blending component with a high cetane number. Its general formula is CH3(OCH2)nOCH3; it is a yellow liquid with a high boiling point, an average cetane number of over 76, and an oxygen content of 47–50%. It represents a clean, high-cetane-number diesel blending component. It contains oxygen but no sulfur; when blended with diesel, it can increase the cetane number and reduce sulfur content, thereby assisting deep hydrogenation technologies in the production of ultra-low sulfur diesel that meets National IV and National V standards. 10% to 20% of it can be added to diesel, which significantly reduces the emissions of particulate matter, soot, HC, and CO in exhaust gases. It can cut exhaust pollutant emissions by over 50%, and is currently recognized worldwide as a component for cleaner fuels.

As far as I know, there are currently five technology providers: two in Shanghai, one in Jiangsu, one in Beijing, and one in Hebei. Of course, their technical approaches, equipment investment requirements, and levels of maturity vary, so it is necessary to conduct evaluations and assessments

Our company, in collaboration with China University of Petroleum and several design institutes, has developed the polymethoxymethane (scientific name: polyoxymethylene dimethyl ether) technology (referred to as “MTCD technology”). You can take a look at it; for more details, you can contact the phone number listed on the website. I work in technology; business matters are not my responsibility. Of course, we can communicate on a technical level. Seeing your message, I thought I’d make a connection for you. http://www.mtcdtech.cn/

As of now, the company with mature technology and industrial-scale production facilities seems to be Runcheng Technology in Dongying, Shandong； In Guangrao County, Shandong Province, there is a 30,000-ton MTCD industrial demonstration facility available for inspection and visitation.

What was said upstairs is not comprehensive; currently, there are several companies that possess industrial facilities. Dongying Runcheng has a facility with a capacity of 30,000 tons, Zibo Jinchang has one with a capacity of 40,000 tons. Shengrong, which is under Héze Yuhuang, has a pilot plant with a capacity of 10,000 tons, and Héze Chenshin also has a pilot plant of 10,000 tons. In addition, there are industrial facilities under construction in Sichuan, Anhui and other places. Beijing Xuyang also has a pilot plant on a scale of 1,000 tons in Hebei.

May I ask if your raw materials are fed in a solid-liquid form or as a liquid? Which type of reactor should be used? We are also studying this matter; could we exchange information on it?

Liquid feed; the reactor is a batch stirred tank. The catalyst is inside

What are your reactants? Our reactant, polyformaldehyde, is a solid

Polyformaldehyde is a solid particle; I thought you were referring to the PODE reactor mentioned later
