The new technology of turning waste into valuable straw and corn bran transformed into biomass oil

The stalks and corn wrappers, which were originally burned by farmers, have been transformed into new clean energy through a new technology. A few days ago, the first barrel of “biomass oil” produced by this new technology was released in Yijun, our province, which not only made the second generation of “biofuel” industrialization in the province the forefront of the country, but also created new revenue for farmers. way.

Biomass oil production uses straw pyrolysis technology and is a national 863 scientific research achievement. When the straw was crushed into 3 mm pellets and entered a closed high-temperature furnace, the temperature rose instantaneously to 800°C, and some of the combustible material gasified to form a gas in the furnace. The gas is introduced into the cooling furnace. After the temperature is reduced rapidly, the gas is rapidly liquefied and the oil is produced. In order for everyone to understand this technology. The coal we use now, the crude oil and natural gas that we use, all passed through for thousands of years. The movement of the earth's crust and vegetation have evolved in the following. With the current technology, this process has been shortened to a few minutes.

According to reports, the biomass oil has a calorific value ranging from 16 megajoules to 20 trillion joules. Using one ton of biomass oil can reduce one ton of carbon dioxide, making it the first choice for high-pollution companies.

According to incomplete statistics, China has more than 700 million tons of straw each year. If comprehensive utilization can replace half of the fossil fuel, it can effectively alleviate the shortage of traditional energy such as coal and oil. In addition, because the raw materials for biomass oil production use field wastes, the sustainable development model of “not competing with people and not competing with grain” has been truly realized, and the economic benefits have been remarkable.

Chen Hongfa, deputy secretary-general of the Ministry of Science and Technology of China, and director of the Center for Promotion of Science and Technology Achievements: This project is of great significance. One is a policy that meets the country's new energy, energy conservation, emission reduction, and renewable resources. Second, it has rich resources and it does not dispute with farmers. The land does not compete for grain, uses wastes for production, the original stalks are burned, and now they are used as raw materials for production to boost farmers' income. Thirdly, they have mastered the core technology, are currently called biomass oil, and will produce zero-size diesel oil in the future. Meet the technical innovation of the Ministry of Science and Technology.
