Recently, the topic of haze once again become a hot topic. When haze can be stopped, many people care about the issue.
Today, with the birth of Xi'an Jiaotong University (Xi'an Jiaotong University) "coal supercritical water gasification hydrogen generation polygeneration technology", smog in the near future may be greatly alleviated.
According to "Daily Economic News" reporter learned that this technology Xi'an Jiaotong University, commonly known as "supercritical steam steamed coal" by the Xi'an Jiaotong University Power Engineering Multiphase State Key Laboratory of Professor Guo Liejin team research and development. The technology can directly and efficiently transform coal chemical energy into hydrogen energy, and eradicates gas pollutants such as sulfides and nitrides and generation and emission of dust particles such as PM2.5 from the source. It is a transformative technology in the coal energy industry .
On December 25, Xi'an Jiaotong University transferred the intellectual property rights and related technologies of the technological achievements to the industrialized investment company at a price of 150 million yuan. The company initially proposed to raise one billion yuan to promote the construction and operation of technology industrialization projects.
Industrialization project officially started in Xi'an
December 25, Xi'an Jiaotong University "coal supercritical water gasification hydrogen power generation polygeneration technology" major scientific research industrialization project was officially launched in Xi'an.
As a transformative technology, there is a fundamental difference between "supercritical water steaming coal" and traditional technologies such as coal-fired power generation and coal gasification power generation.
"Conventional coal-fired power generation, including coal gasification and power generation, uses coal to burn in the air and oxidizes it with oxygen, which is an exothermic process that can be used. In a coal boiler, it is absorbed by the water in the boiler, and then it turns into steam, which in turn drives the steam turbine to work, which is often referred to as steam turbine power generation. "Professor Guo Liejin told the Daily Economic News reporter.
Guo Liejin also said that more efficient use of steam turbine power generation, there is also called gas turbine power generation. However, due to the device's material to be more high temperature, higher performance requirements, so the process is particularly difficult. "All of these technologies were developed abroad from the very beginning, and we just followed others to learn, though our industry is the most successful."
"Oxidation will naturally produce sulfur dioxide and nitrogen oxides, coupled with the particulate matter raised when the coal combustion, PM2.5 is the way to come." Professor Guo explained, "Enterprises to desulfurization and denitration dust, it is necessary to install dust removal device The cost is high for the business, and having to run these devices at the same time consumes less energy, so the overall efficiency is not high, on the average 40%. "
For the research and development of "supercritical water steaming coal," Professor Guo Liejin explained in a plain way, "We are now the technology without air into the coal and water is mixed together, let it react. The whole process is not oxidation reaction, but the reduction reaction."
"The traditional combustion process I did not, I burn hydrogen, get water, so my product is clean and then get high temperature and pressure of supercritical water vapor, the same can make the steam turbine work. The resulting efficiency ratio Traditionally high, there is no pollution. "
The transferee company intends to raise 1 billion to promote industrialization
In fact, Xi'an Jiaotong University this "supercritical water steaming coal" technology has just come out, it triggered the industry shake. This reporter has learned that the technology has now completed a complete principle of innovation, laboratory regularity pilot study and part of the pilot test.
On the 25th, on the industrialization project achievement conference, Xi'an Jiaotong University transferred the intellectual property rights and related technologies of the technological achievements to Shaanxi Superinvertebrate Energy Technology Co., Ltd. at a price of 150 million yuan. The reporter of "Daily Economic News" noticed that the company is a joint-stock company that was jointly founded by three companies including China Allianz Investment Fund Management (Beijing) Co., Ltd., Hong Kong Nichiren Investment Co., Ltd. and Xi'an North Qi Energy Technology Development Co., Ltd. Industrial Investment Company.
According to the statistics, China Allianz Investment Fund Management (Beijing) Co., Ltd. was established in 2012 with a registered capital of 350 million yuan. Its principal business is investment management of non-securities businesses and is a subsidiary of China National Nuclear Construction Corporation. Press inquiries found that the company also had in January this year signed with the South pump the establishment of M & A fund agreement, the initial fund size does not exceed 1 billion yuan for the environmental technology industry.
Shaanxi Nuclear Power Jiaotong University Super Clean Energy Technology Co., Ltd. announced the same day that it will initially fund the construction of a demonstration project of industrialization of technology with a total amount of 1 billion yuan. At the same time, it will strive to complete the construction and operation of the project in 3 years.
"This technology is also being studied abroad, but it is behind us." Guo Liejin told reporters, "They did not form a large-scale continuous production plant, our large-scale pilot plant, has been running for thousands of hours in a row No problem now.At present, all kinds of coal chemical industry also have to produce hydrogen, but also steam, as long as replace some of the units, you can use.
"All industrial enterprises that use coal as raw material can use this technology." Professor Guo emphasized.
