Fuel ethanol project can solve the problem of straw burning aggravating haze
since the beginning of winter, haze has once again become the focus. On November 8, the average PM2.5 in Shenyang reached 1155 micrograms/cubic meter, and the local haze index once exceeded 1400 micrograms/cubic meter. On the same day, 21 cities in Northeast China had severe air quality pollution or above. On November 11, the Ministry of environmental protection issued the letter on informing the prevention and control of straw burning pollution from November 2 to November 8, 2015, which showed that since November, straw burning has occurred in Northeast China, and straw burning has had a serious impact on atmospheric environmental quality
"cellulosic fuel ethanol made from straw can effectively solve the problem of straw burning in the open air." Wu Guoqing, deputy director of the national energy bio liquid fuel research and development (experimental) center, said
straw burning intensifies Urban Haze
straw burning emits a large number of air pollutants such as sulfur dioxide, nitrogen dioxide, inhalable particles, etc. banning Jinan Fangyuan experimental machine factory from specializing in the production of universal material experimental machines and stopping the burning of straw has become one of the priorities of environmental protection in recent years<40 ~ 77hrdp> from November 2 to 8, the statistics of environmental satellite remote sensing monitoring data showed that 885 suspected straw burning points were detected in 13 provinces (districts and cities) such as Heilongjiang, Jilin and Liaoning, an increase of 556 points over the same period in 2014, an increase of 169% Among them, 663 in Heilongjiang, 119 in Jilin and 54 in Liaoning are the three provinces with the most fire spots. Among them, the straw burning phenomenon in Heilongjiang and Jilin provinces is particularly prominent, with an increase of 645% and 120% respectively over the same period in 2014, which has a serious impact on the local atmospheric environment quality
it is also understood that China's annual straw output is more than 700 million tons, of which about 150 million tons are burned in the field, causing serious air pollution, and sometimes even affecting highway traffic and aircraft take-off and landing. "At present, it is the winter heating season in northern China, and it is also the season when straw burning occurs frequently. Many places have taken measures to prohibit straw burning, but the relevant problems have not been fundamentally solved. Making straw into cellulose fuel ethanol can effectively solve this problem." Wu Guoqing said that each kilogram of straw can directly reduce PM2.5 emissions by 20 gramsIn July this year, the general office of the State Council issued the opinions on accelerating the transformation of the mode of agricultural development, which clearly requires promoting the resource utilization of agricultural waste and accelerating the construction of straw collection, storage and transportation system
"thanks to this, the fuel of biomass comprehensive utilization project will be fully guaranteed." According to Wu Guoqing, cellulosic ethanol is recognized as the development direction of fuel ethanol industry in the world. At present, cellulosic ethanol technology using agricultural and forestry wastes as raw materials has made continuous progress in the world, and a number of industrialized devices have been put into operation and under construction
Wu Guoqing said, "China's cellulosic fuel ethanol technology is on the eve of a breakthrough in industrialization. COFCO group, the largest fuel ethanol supplier in China, has a 500 ton cellulosic ethanol experimental device with an annual output of 10 years of mature operation, and the 50000 ton cellulosic ethanol 6 megawatt biomass power generation project currently being promoted has also met the conditions for commercial operation."

"but it should be noted that at present, China's support for cellulose ethanol research and development and industrial development is insufficient, resulting in the industrialization process of cellulose ethanol in China lagging behind the international advanced level." Wu Guoqing said, for example, the renewable energy law promulgated by the state has made clear provisions on the promotion and use of ethanol gasoline for vehicles, but there is a lack of more operational policy implementation rules, which makes it difficult to promote
it was learned that on November 3, in order to comprehensively study and implement the spirit of the Fifth Plenary Session of the 18th CPC Central Committee and promote the sustainable and healthy development of China's energy industry, the CPPCC National Committee held a symposium on the theme of "optimizing the layout of new energy and promoting the healthy development of clean energy" in Beijing. During this period, Li Yizhong, member of the CPPCC National Committee and former Minister of the Ministry of industry and information technology, made a speech on "paying attention to the development and utilization of biomass energy"
Li Yizhong said that biomass energy is the only renewable energy that can directly produce gas, liquid and solid fuels and replace refined oil and natural gas. "In June 2014, the State Council issued the strategic action plan for energy development (), which mentioned the development of a new generation of non grain fuel ethanol and biodiesel, and the development of rural renewable energy according to local conditions. Biomass energy is an important renewable energy, but now it is not paid enough attention." Li Yizhong said, "at present, the sharp decline in international energy prices has brought pressure to the development of new energy, but we can't relax the development and utilization of new energy. Most of new energy enters the market in the form of electricity. Only biomass oil and gas can replace oil and natural gas. Therefore, we shouldn't relax the research and development of biomass energy utilization technology, which can at least be used as a strategic reserve under the current oil price."
Li Yizhong suggested that relevant departments should investigate and formulate tax reduction and exemption support policies; For the problem of raw material collection, the government needs to make unified arrangements, carry out pilot projects, form a recycling industrial chain, and promote it after gaining experience; At the same time, oil and gas production from biomass energy should enter the existing oil storage system and sales system
