Biomass energy, as the name implies, is the form of energy stored in biomass by solar energy in the form of energy, ie biomass-based energy. The trees around us, the stalks in the farmland, animal waste, biogas and so on are all biomass energy. Because organisms are directly or indirectly from the sun, so biomass can also be said to be a generalized solar energy. Human earliest history of energy use is also derived from biomass energy. In recent years, great progress has been made in the field of biomass energy. Two cutting-edge technologies have emerged in the field of biomass energy. The first is bio-fermentation conversion of industrial waste gas and the second is algae fuel technology. The two new technologies promote biomass Can go to the energy front desk. The core of "Bio-Fermentation Transformation Technology for Industrial Emissions" is the conversion of industrial waste streams containing carbon monoxide to fuel using microbial fermentation. The basic principle is that carbon monoxide or carbon dioxide and hydrogen are converted to ethanol, acetic acid or other products by bacterial anaerobic fermentation. So this technology so everyone is very concerned because of its raw materials can be obtained from any biomass resources, rich resources, while taking full advantage of the original waste resources, such as urban waste, discarded tires, as well as emissions from steel mills, etc. ; It can also be closely integrated with the existing steel, coal industry, extend the industrial chain, increase the added value of the industrial chain, has a very strong applicability. At present, Lanze Technology Co., Ltd. in New Zealand has mastered the key technology of the process and is promoting the industrial application. In 2011, Langze cooperated with Baosteel in the construction of a 300 tonne / year steelmaking tail gas to ethanol project, which will promote scientific data on the industrialization of ethanol from tail gas plants in the world. In December 2011, Langze Technology cooperated with Yankuang Group to produce liquid fuels and other products from syngas generated by Yankuang's coal gasification plant. At present, Shandong Energy Group is also actively engaging with Lanze Technology. Shandong Energy Group owns the coke oven gas methanol and coal methanol industry and the largest coke oven gas LNG (liquefied natural gas) project in the country Will be ample excess of hydrogen, so that you can use the technology, as raw materials for the production of ethanol or fuel oil fermentation. This will also be Shandong Energy Group involved in the field of new energy an attempt. The invention of "algae fuel technology" is equally significant. Algae photosynthesis ability is very strong, its unit of fuel is the highest in biofuels. At present, only about 6,000 liters of biofuels can be extracted from the rapeseed oil grown per hectare of land, but the same area of ​​algae can extract 80,000 liters of biofuels. Algae growth and adaptability, fast growth, low requirements. Algae need sunlight, water and carbon dioxide to grow. In just one day, its number can be quadrupled. Another feature of algae is to absorb carbon dioxide and "produce oil" through photosynthesis. As we all know, carbon dioxide emissions are the culprit of global warming, so using algae to create energy, but also reduce carbon dioxide emissions, can be described as double benefit. However, the development of algae energy faces the problems of cost and ecological security. First, the cost of preparation. In the 1970s, scientists at the National Renewable Energy Laboratory spent 17 years conducting feasibility studies on alternative energy sources for algae. In those days, scientists tested algae in open ponds and found that algae fuel was produced in algae farms built in shallow ponds that provided enough biodiesel to replace fossil fuels for transportation and domestic heating. However, in 1996 they discontinued the project because, after calculation, they considered the cost of producing biodiesel through algae too high. Although algae research advances a lot at present, but large-scale commercial development also takes a long time. Second, ecological security issues. On the one hand, some experts pointed out that many gene technologies are used in the research on the production of fuel by algae. The most serious consequence is that the genetically modified algae may escape human control, return to nature, replace other species, lead to overgrowth of algae, Destroy the original ecosystem. On the other hand, algae play an important role in the environment. The oxygen produced by their photosynthesis is an important source of atmospheric stability and the basis of the marine food chain. Whether large-scale development will have adverse effects remains to be demonstrated. How far can biomass energy that has come onto the energy front? We'll see. Other Concrete Pump Spare Parts
