9.Summary of Research Results
|
An environmental friendly industrial municipal system based on coal energy matching with the southern area of
China is studied. The emphasis is placed on the development and examination of the elemental technologies
and systems to realize the proposed new total system from the combination of them. This project was organized
by Nagoya University, and was accomplished by the joint research group of Japanese and Chinese academic
researchers. The following main results were obtained: 1. An efficient power generation system by pure
oxygen combustion of coal is proposed, and the stable combustion was studied by the examination in the drop
tube furnace. 2. A city gas production process from Refuse Derived Fuels (RDF) in the circulating fluidized
bed is developed, and gas with higher heating value than 20MJ/m3 was produced by the system. 3. The
lifecycle evaluation of the civil engineering structures, especially transport infrastructures, was performed to
reduce the total environmental load such as the CO2 emission and energy consumption. 4. The estimation of the
amount of pollutants discharge in the atmosphere and its adverse impact on environment is carried out, and an
advanced future transport system using clean energy in Guangzhou metropolitan area, China was proposed. 5.
The evaluation of the energy saving potential by the introduction of decentralized energy plant was performed,
and the total operation technology of the central energy system and various decentralize energy plants are
developed. 6. Hybrid separation techniques for complete recycling of metallic compounds composed of
harmful elements, such as Ga-As scrap and Se-As scrap, were developed. 7. The process to treat the surface
water containing the humic substances by adding both the polyaluminum chloride and the powdered activated
carbon and filtering with the ultrafiltration membranes was developed. 8. The analytical methods for
environmental monitoring and multielement determination of about 40 elements and chemical speciation of
trace metals by using ICP-MS (inductively coupled plasma mass spectrometry) have been developed to
evaluate the pollutants in the environment. 9. A system of Clean Development Mechanism and its influence to
China is surveyed, and environmental law system and policy at Local Levels (Canton Province and
Guangzhou ) are inquired. |
