Coincidentally, in 2007 , Chinese Academy of Sciences released " Technology Foresight next 20 years ," the report said , the proposed enzymatic ( biomimetic catalysis ) technology will be widely used.
In the meantime, the State Council Academic Degrees Committee of Discipline Review Group ( chemical group ) member , Hunan University doctoral tutor Professor Guo Cancheng research , contributed to promote the formation of this discipline .
Witness a new round of the biotechnology revolution
OECD states: " industrial biocatalysis technology for sustainable development of the most promising technologies ." Biomimetic catalytic oxidation technology is one of the three biological application of technology in the 1970s formed . Many developed countries, international research goal is to establish a new environmentally friendly catalytic process , which involves a large number of changes in the national economy and the traditional chemical processes .
After several years , due to the difficulty of their research , many scientists left the field . However, Cheng Guo continued support of the National Natural Science Foundation of China and the " 863" Project, stick in the field for nearly 30 years , guiding postdoctoral , doctoral and master more than 100 , forming hydrocarbons may be industrial applications biomimetic catalytic oxidation technology.
August 29, 2003 , Sinopec Yueyang Chemical Plant Applications Cheng Guo developed biomimetic catalytic technology in 45kt / a cyclohexanone large industrial equipment , conducted the first international test case of biomimetic catalysis for industrial applications . Lower than the conventional process temperature and pressure conditions , the reaction does not change the main unit , using only a simple 1 ~ 2ppm concentration of metal porphyrin, cyclohexanone plant capacity can be doubled , and cyclohexanone production costs can be reduced by 15% .Sellotape
Since the process of biomimetic catalytic process avoiding polluting traditional process , the process can also significantly reduce environmental pollution. Industrial weeklong trial showed that a simple biomimetic catalytic metal porphyrins air oxidation of cyclohexane production of cyclohexanone technical feasibility .
2004-2005 , Sinopec Baling Company on 70kt / a cyclohexanone introduction of large-scale industrial installations , conducted a two-year industry biomimetic catalytic continuous stability test . The results show that Cheng Guo technology has developed biomimetic catalytic performance on large-scale installations and stable operation . The project marks the application of biomimetic catalysis technology has been an international leader .Washi tape
Cyclohexanone is the manufacture of caprolactam , adipic acid and other nylon intermediates required in the production of raw materials , in the present international industry obtained from cyclohexane oxidation. The air oxidation of cyclohexane production of cyclohexanone is considered to be the least efficient international chemical processes. Biomimetic catalysis technology with new technology of independent intellectual property rights , and is expected to solve the industrial production of cyclohexanone conversion rate , environmental pollution, high cost problems. When Wang Jiming , president of Sinopec ,Masking tape
said the technology will bring several hundred million dollars annually in economic benefits petrochemical . And Senior Vice President of Sinopec Cao Xianghong when he said, hoping the two sides to further cooperation between schools and enterprises , promote the use of new technologies for preparing cyclohexanone , set off the "new revolutionary tradition of chemical oxidation process ."
Academicians , the "Father of the catalyst of the " Min Enze evaluation of its achievements in recent years, one of the three areas of green chemistry China leaps of progress.Wholesale masking tape
