CNPC News: “Planting†Gasoline from Farmland? Crops become a material source from fuel to plastics? These assumptions, through biotechnology, are not only possible but also feasible and even profitable.
“If we use half of our current resources, we can build a green oil field with an annual output of 50 million tons, which is equivalent to an annual output of Daqing.†Today, at the “2005 China Biomass Engineering†forum of the Chinese Academy of Engineering, the The feasibility of material energy, Shi Yuanchun, an academician of the two academies, calculated the accounts with confidence. At the same time, several academicians and professors from the technological frontier in this field conducted in-depth discussions on the development trend of international biomass technology, the current status of China's biomass engineering technology, and the challenges and industrialization prospects.
“In recent years, there has been an important trend in the world, that is, as petrochemical energy sources are becoming increasingly depleted. In the pursuit of sustainable development, environmental protection and circular economy, the world has begun to focus on renewable energy sources and materials. 'Biomass economy 'It has surfaced.' Shi Yuanchun explained that the biomass economy is based on the abandonment of biomass in agriculture and forestry and the use of low-quality production of energy, chemical plants, and engaged in the production of high value-added products.
Academician Stone called plants the best “processing plant†and “reservoir†for hydrogen energy. He said: "Although solar energy, wind power, small hydropower and other renewable energy sources can provide energy, we can't produce materials on our own, and bioconversion technology allows us to directly use plants to provide energy. Biomass can both contribute energy and be like Thousands of chemical products are produced from coal and oil."
As agriculture begins to expand into the energy sector, “waste†such as livestock and poultry manure, agricultural and forestry crops, and their remnants can all become “babyâ€. Experts believe that "biomass energy" will become the most potential new energy source in the 21st century.
"At present, the total amount of biomass in the world is as high as 6.91017 kcal/year. Unfortunately, the utilization rate is only 3%," said Li Shizhong, deputy director of the China Agricultural University Student Material Engineering Center. Taking China as an example, 200 million tons of straw are burnt in open ground every year. 2.5 billion tons of livestock and poultry excrement pollute the environment. Nearly 200 million mu of farmland is covered by plastic mulch and soil fertility attenuates. “Actually, this is a huge waste. We must let farmers realize that they are not just burning straw but are burning money.†Zhen Zhenyuan, secretary of the Party Committee of China Agricultural University, urged that the road to industrialization should be accelerated so that biomass energy can benefit farmers and even every one. Drive the driver.
According to Shi Yuanchun, the biomass industry has been promoted as a national strategy in developed countries such as Europe and the United States. As early as 2000, the United States Congress passed the "Biomass R&D Act" and proposed an ambitious goal in the development of the biomass economy (2020): Biofuels replace 10% of national fuel consumption (50% in 2050) ); To replace 25% of the national petrochemical raw materials; To reduce the equivalent of 70 million cars of phosphorus emissions (100 million tons). At the same time, EU, Japan, India, Canada and other countries have also issued relevant plans.
The latest research report released by the OECD on September 6, 2004, recommends that governments of all countries should vigorously support and encourage technological innovation in the field of biomass energy, reduce the price gap between it and traditional crude oil and natural gas products, and ultimately achieve alternatives. result.
According to Shi Yuanchun, the development of biomass energy in China is very realistic. "Our country's oil reserves are 2% of the world's total, consumption is the second largest in the world, and the degree of import dependence is nearly 40%. The emissions of SO2 and CO2 also rank the first and second in the world. China is not only rich in raw materials, but also has its own The cultivation of sweet sorghum and other fine energy plants; fuel ethanol, biodiesel, bio-plastics and other main products industrial conversion technology is basically mature and there is room for improvement, the cost reduction is generally 25% to 45%%. Currently in Xinjiang, Shandong Sichuan and other places have begun to make progress.
Talking about the development of biomass technology, Li Shizhong said that although China's overall level is low, the key technologies for bio-utilization of three plant biomass have been achieved in the internationally recognized lignocellulosic hydrolysis, bio-utilization of fermentable sugars, and the separation and purification of metabolites. breakthrough. The 35th Engineering Science and Technology Forum of the Chinese Academy of Engineering -- the "2005 China Biomass Engineering Forum" was opened at the Great Hall of the People in Beijing on the 28th. Experts at the meeting called for the time for the development of the biomass industry in China to be mature. China should take advantage of resources, technology, and talents to establish this sunrise industry and open up a "third battlefield" for agricultural efficiency and farmers' income increase.
Academician Shi Yuanchun of the Chinese Academy of Engineering said that the biomass industry refers to the use of renewable or recycled organic materials, including crops, trees and other plants and their residues, livestock and poultry manure, organic waste, and the use of The marginal land is planted with energy plants as raw materials for bio-based products, biofuels and bio-energy production industries. This emerging industry not only provides energy like renewable energy such as solar energy, wind power, and small hydropower, but also produces thousands of chemical products like coal and oil. In China, 200 million tons of straw are burned every year, and 2.5 billion tons of livestock and poultry excrement pollute the environment. Nearly 200 million mu of farmland is degraded due to plastic mulch and the soil fertility is attenuated. The development of the biomass industry is another way to enrich agricultural and forestry waste. Non-farmland and non-farmland are used as raw materials and bases to make harmless and resourceful agricultural and forestry wastes and pollutants, and to produce energy and bio-chemical products with a broad market, environmental friendly, and high added value.
This authoritative agricultural expert said that this will be the “third battlefield†opened up for agricultural efficiency and peasant income increase after traditional agriculture expands from primary agricultural product production to agricultural product processing. If China can use half of its current resources, the annual output value of the biomass industry can reach nearly RMB 1 trillion.
The strategic orientation of China's biomass industry is mainly focused on solving the “three rural issues†problem, and it combines the development of bio-energy and environmental protection. Shi Yuanchun proposed that in the historical transformation of China's energy structure, China has strong practicality and feasibility in developing biomass energy: not only is it rich in raw materials, but also has its own energy plants such as sweet sorghum and Jatropha curcas; fuel ethanol, The industrialized conversion technologies of biodiesel, bio-plastic, and other main products are basically mature and have much room for improvement. Bioenergy has begun to make progress in places such as Xinjiang, Shandong and Sichuan. If we can use half of our existing resources, we can build a “green oil field†equivalent to a Daqing annual output of 50 million tons.
Officials from the Ministry of Science and Technology revealed that the relevant contents of promoting the development of the biomass industry have been included in the research scope of the national medium and long-term science and technology development plan. Experts said that China has many advantages in this regard. As long as the work is in place, there is hope that it will lead the world in the biomass industry.
In another five years, perhaps a quarter of the cars running on the street burn ethanol made from crop straws or almost no pollution "biodiesel." At the Bioengineering Science and Technology Forum held yesterday by the Chinese Academy of Engineering, Shi Yuanchun and other five academicians from the Chinese Academy of Engineering stated that China’s emerging biomass industry is already at the leading position in the world. After five years, the production capacity is expected to reach the production capacity of Daqing Oilfield, becoming an annual output of 5000 Ten thousand tons of "green oil fields."
Biomass engineering is one of the most cutting-edge research projects in China's engineering technology. Biomass mainly refers to straw, wood and other wood fiber and other agricultural and forestry waste and livestock manure. Producing non-polluting chemical products and green energy by using them as raw materials is the only way for human beings to achieve sustainable development, and it is highly valued by all countries in the world.
China's related biotechnology has been basically mature. At present, China has made important progress in three internationally recognized key technologies such as hydrolysis of lignocellulose, separation and purification of metabolites. China's biomass resources are extremely abundant. A total of 1,554 species of plants can be used as raw materials for biomass fuel production. Each year, 700 million tons of straw and 2.5 billion tons of livestock manure are produced. The autonomously cultivated sweet sorghum can produce 48 liters of ethanol per hectare per day. It is a high-quality raw material.
Experts said that the development of biomass energy is crucial to China’s energy security. China's oil reserves are only 2% of the world. In 2004, nearly 40% of the country's oil imports depended on imports. This is estimated to require 56% to 60% of imported oil in 2020.
