A few days ago, it was learned from China Petroleum & Chemical Corporation that the company’s R&D team took a breakthrough in cellulosic ethanol production technology over a seven-year period, and innovatively developed a variety of raw materials, such as corn stalks, to form a complete set of cellulose-based ethanol production technology.
According to statistics, China can collect about 700 million tons of straw each year, except for papermaking, feed, fertilizer conversion, and loss collection. According to the remaining 20% ​​of straw, about 140 million tons of straw each year can be used to produce ethanol. According to 5 tons of straw produced 1 ton of ethanol, the annual output can reach 28 million tons. The development and utilization of straw and other agricultural and forestry wastes to produce fuel ethanol will be calculated based on a net income of 200 yuan per ton of straw, and it will also increase farmers' income by 28 billion yuan each year.
According to reports, China began to pilot the use of fuel ethanol in 2001 and has now become the third largest producer and application country of biofuel ethanol in the world. Sinopec formed a cellulosic ethanol technology research and development team in 2007 to tackle technological problems and integrate a full set of key technologies. At the end of 2013, Sinopec's technical team completed the development of an annual production capacity of 50,000 tons of cellulose-based ethanol technology packages, which could provide technical support for the construction of 10,000-ton demonstration units.
