On the 26th, the reporter learned from Sanju Environmental Protection that after more than 5 years of independent research and development, it has made a major technological breakthrough in the field of biomass direct liquefaction. Independently repeat the test and evaluation.
According to the data of the repeated test results of the Chinese Academy of Sciences, for the corn stalk raw material of this test, about 2.1 tons of straw can produce 1 ton of primary biological liquid fuel with an oxygen content of less than 5%. The evaluation report shows that this technical route can reduce processing costs, improve oil quality, and significantly reduce wastewater discharge.
"Compared with existing technical routes for biomass fuel ethanol, biodiesel and bio-jet coal, raw materials for direct biomass liquefaction technology are readily available and cost-effective, and agricultural and forestry wastes can be directly converted in large quantities under the action of catalysts. Into liquid clean fuels and chemicals based on hydrocarbons, "said Dr. Cui Yongjun, who is responsible for the development of this technology.
"At present, no other company in the industry can achieve this degree, because we use an independently developed catalyst and a special deoxygenation process, and organically combine with the suspended bed technology, which is more economical in cost." Cui Yongjun said, The team developed a high-efficiency and low-cost catalyst, breaking through the problems of efficient deoxygenation technology and avoiding the generation of large amounts of organic wastewater. At the scientific and technological achievement appraisal meeting organized by China Petroleum and Chemical Industry Federation on June 21, the appraisal committee believed that the suspension bed hydrogenation (MCT) heavy oil processing technology independently developed by Sanju Environmental Protection had reached the world's leading level.
The conclusion of this independent repeated test is consistent with the company's test results, indicating that the technology has initially met the conditions for industrialization. It is also reported that it plans to build 3-5 sets of standardized industrial demonstration devices with a scale of 200,000 to 300,000 tons in the next three years; to achieve full industrialization in the next five years, that is, to establish a number of standardized distributed biomass liquefaction plants to achieve 5 million The total production capacity of tons has initially formed a large-scale upstream and downstream industrial layout. In response to this technology, the company is establishing an intellectual property protection system and has applied for a total of 80 invention patents. (Reporter Ma Aiping)
