In order to solve the fuel shortage problem, China started its fuel ethanol program as early as 2000. In April 2001, the two national standards of “modified fuel ethanol†and “special ethanol gasoline†were formally announced. Since June 2002, ethanol gasoline for vehicles has been piloted in Henan, Heilongjiang, Jilin and Anhui provinces, and has been successfully implemented in some provinces after the success. It is understood that most of the fuel ethanol in these provinces is produced from corn.
At the same time, as the main sugarcane producing area in Guangxi, the idea of ​​producing ethanol from sugarcane as raw material was proposed. The Guangxi Academy of Agricultural Sciences provoked the burden of research and development.
According to Li Ruiyang, dean of the Guangxi Academy of Agricultural Sciences, Guangxi has officially started research and development to produce ethanol from sugar cane as a raw material last year. As the energy crisis is an urgent issue on a global scale, many countries are trying to produce alternative energy sources using various biological raw materials. Brazil is one of the countries that earlier mastered the direct processing of fuel products from sugar cane.
Li Ruiyang and other researchers who have been carrying out new product development have put forward the concept of “energy caneâ€, which can be used to produce sugar cane for fuel ethanol. Using "energy cane" to produce ethanol, the output will be 1 to 2 times that of ordinary sugar cane. After solving the problems of technology and equipment, the issue of sugar cane production was placed in front of the research and development team. After repeated trials, the Guangxi Sugarcane Research Institute bred a new cane sugar cane variety, Guitang No. 22, this year. The average yield per hectare of cane increased to 121 tons, which is also very high in the world.
In order to solve the waste liquid treatment technology problems encountered in the production of ethanol from sugarcane, Guangxi has already conducted “quantitative field return†experiments in the key sugarcane producing areas such as Shangsi and Chongzuo. The current experiment has been successful and is now being further summarized. Complete use of technology. It is understood that the implementation of this technology will completely eliminate the use of chemical fertilizers in sugarcane fields, but will put large amounts of nutrient-containing ethanol waste back into the land. The "quantitative returning field" technology has been listed as a key promotion program in Guangxi by the Sugar Department of Guangxi Agriculture Department.
According to reports, Guangxi, as the main sugarcane producing area, is fully qualified to carry out energy ethanol projects. Moreover, with the solution to the two major problems that have plagued energy ethanol production: “liquid waste treatment†and “capacity increaseâ€, the technology of sugar cane energy ethanol has also matured. However, this does not mean that "energy sugar cane" can be widely promoted soon. Its main problem is that market conditions do not yet exist.
Judging from the current situation, 7.8 tons of sugar cane can produce 1 ton of sucrose, but the production of 1 ton of ethanol requires about 13 tons of sugar cane, and the combined sale price and production cost of sucrose and ethanol are not economically economical. Cost-effective, so the traditional way of sugar cane production is more optimistic about the farmers. Moreover, the same is the production of ethanol, the current price of edible alcohol in China is about 4,500 yuan / ton, the price of industrial ethanol is only 3,300 yuan / ton, and the higher prices of edible alcohol market demand. Therefore, Guangxi's conditions for the development of sugarcane fuel ethanol can be said to have matured initially, only to be regulated by the market's "East Wind", and this may also depend on the state's relevant departments to take certain support measures.
