| 标题： Energy, Environment and Living Crisis | |
| 摘要： People are searching for clean and sustainable energy, and great efforts have been dedicated to utilization of hydrogen energy, nuclear energy, shale gas, flammable ice and all kinds of natural energy to avoid of burning coal. To the author’s opinion, these ideas may not be correct. Hydrogen energy is still far away from reality due to existence of two barriers. First, hydrogen energy must base on reproducible hydrogen, i.e., the hydrogen comes from water, but not from any fossil fuels; second, the hydrogen must be densely and safely stored on moving objects. However, these barriers have not been taken away even theoretically. Nuclear energy includes fission and fusion energy. The former has been widely applied in practice, but how to deal with the long term (hundred thousand years) radioactivity of reactor residue is still a serious challenge; the latter is believed to be an endless energy source, although the resources of lithium, an inevitable material for fusion reaction, is quite limited. Exploitation of shale gas depressed the price of crude oil, however, a lot of fresh water expends, not mention the possible damage on environment. The resource of flammable ice is shown much more abundant than other fossil fuels, but ecological disaster might happen on exploiting not mention the shortage of sophisticated exploitation technology. All kinds of natural energy have a common problem: storage of the energy producedunevenly. This problem is a serious challenge for extensive utilization of them. Besides, it has been indicated that natural energy alone cannot satisfy all human requirements for energy. To the author’s opinion, coal is the most reliable clean energy because zero emission is guaranteed when“carbon reduction” is applied to the flue gas of power plants. Methanol as by-product of such power plants will be widely used in fuel cells to provide power for miscellaneous moving objects. Deterioration of environment is usually attributed to the expenditure of fossil fuels. This is very superficialcomprehension of nature. Although CO2 is released on burning fuels, the global emission of CO2 is linearly correlated to the world population, and zero emission is recorded when the population is less than 1.3 Billion. The ecological crisis is caused by over large population of the world. The present world population is 7.5 billion and it increases exponentially. The world must consider which will sustain longer, the energy source or human kind itself. | |
| 简介： 1959-1965：Study in the Dept. Eng. Chem., Tsinghua University, and started the academic career in Tianjin University since then. Promoted to Professor in 1990 and retired in 2009. 1981-1983: visiting scholar in the Dep. Chem. Eng., University of Wisconsin-Madison, USA majored in process systems engineeringwith advice of Professor Richard Hughes, the President of AIChE that time. 1992-95: cooperative research in the Institute of Hydrogen, Univ. of Quebec, Canada. Elected to Director Board of Int. Ads. Soc. for 2004-2010. Hosted the 4th Pacific Basin Conference on Ads. Sci. &Technol. Tianjin，2006. Ten independent or collaborate books or monographs written in Chinese/English. More than 140 journal articles were published in Chinese/English. H-index=27. Marquis’ Who’s Who in the World since 2005. Major achievements in energy research: 1. Clarification of the adsorption mechanism at above-critical temperatures and its impact on the research of storage materials for H2/CH4. 2. Hydrogen energy is shown still far away from reality because the way to solve problems of producing re-generable H2 and storage of the latter have not been lighten up. As results, the great mass fervor for hydrogen energy development fell down. 3. Invention of a storage method for methane-majored fuels on wet activated carbon that reached almost same volumetric storage capacity as CNG (200 V/V) at half pressure. 4. Invention of a PSA (pressure swing adsorption) process with CO2 displacement to enrich methane from methane-contained fuels, with which both product concentration and methane recovery reached 95 % from lower than 20 %. 5. Proposed forced carbon circulation (FCC) strategy to replace the well-known CCS (carbon capture and storage) strategy. Basing on FCC strategy regenerated H2 is possibly to produce in large scale and coal is easily changed to green power source through carbon reduction. Methanol, as by-product of green coal power, will become a common fuel of fuel cells, which are especially suitable for moving objects. 6. Clarification of the relationship between energy and environment. It is the over-loaded world population, but not the expenditure of energy, responsible for the damage of environment. | |
