At present, with the rise of international food prices and the widespread concern of food security issues, the development model of biomass energy using ethanol as a raw material as a raw material has been controversial because it threatens food security. To this end, scientists began to look at the 1.5th generation non-grain bioethanol, the second generation of cellulosic ethanol, the third generation of microalgal diesel, and the bio-kerosene represented by cassava, jatropha, and seaweed.
“The United Nations Industrial Development Organization is committed to helping the backward countries and regions to develop the biomass energy industry.†George, the head of the biotechnology project department of the United Nations Industrial Development Organization, said that there are large areas in many backward areas in the world that are not suitable for the cultivation of rice, corn, soybeans and other food crops. The barren lands, if cultivated on these lands, such as cassava and jatropha, will not only help the local people increase their income, but also provide more raw materials for the biomass energy industry.
While vigorously developing non-food biomass energy and improving the technological level of biomass energy utilization, China has made great progress in exploration and practice. "With the development of science and technology, the problems of biomass energy, food for people, and disputes for grain can be solved." Dr. Yang Huanming, academician of Chinese Academy of Sciences and president of Shenzhen Huada Gene Research Institute, said that as a new industry The development of biomass energy currently depends to a certain extent on grain cultivation, but with the development of science and technology, the use of marine algae to produce biodiesel, and the use of artificial bacteria or embryonic microbes to produce energy alternatives such as gasoline and diesel have tended to tend to Mature, biomass energy industry can gradually get rid of dependence on farmland.
As an important biomass energy base in southern China, after several years of development, Guangxi has already possessed a number of renewable energy energy enterprises such as bio-ethanol, bio-diesel, and biomass power generation. Currently, it has been scaled by Guangxi Zhongliang Biomass Co., Ltd. Substance companies, Liuzhou Minghui Biofuels Co., Ltd., and Funan Bioenergy Co., Ltd. used raw materials such as cassava, jatropha, bagasse, straw, and other non-food crops.
According to Huang Ribo, deputy chairman of the Guangxi People's Political Consultative Conference and president of the Guangxi Academy of Sciences, Guangxi is actively developing the use of cassava, bagasse, straw, marine microalgae and other tropical and subtropical resources in southern China to expand the range of raw materials required by the bio-industry and actively overcome major bottlenecks. With key technologies, it is proposed to develop bio-refinery technology and build a green biomass energy industry that does not compete for food or land.
Nickel-based alloy wire owns good resistance to high reactive gases, caustic resistance medium and acid corrosion performance, and also owns high strength, good capability of shaping, hot and cold forming and welding deformation. Therefore it is widely used in petroleum chemical industry, metallurgy, atomic energy, ocean development, aviation, aerospace to solve the problem that general industry, stainless steel and other metals, non-metallic materials engineering corrosion problems could not be solved,it is a very important kind of corrosion resistant metal materials. Nickel based alloys are nickel based alloys that contain alloy elements and which can be resistant to corrosion in a number of media. To classify the chemical composition characteristics, mainly nickel, nickel copper alloy, nickel alloy, nickel chromium molybdenum (Nie Mutie) (iron nickel alloy), nickel chromium molybdenum (including Ni Cr Mo alloy and Ni Cr Mo Cu alloy) and nickel iron chromium (both iron nickel alloy) and other types of. Pure nickel welding wire ERNi-1 for welding of 200, 201 nickel alloy and nickel plated steel plate; steel and nickel dissimilar materials welding; steel surface surfacing.
