13 The objective of this project are to elucidate the thermal characteristics of
plastics such as polyolefin, polyvinyl chloride, polyvinylidene chloride and
their mixtures, and to develop the dechlorination technique by thermal
treatment, prior to converting waste plastics to oils or other useful
materials.
Thermal properties of low and high density polyethylene(PE),
polypropyrene(PP), polystyrene(PS) and polyvinylchloride(PVC) were analized
in the range from 40 oC to the decopmosition-vaporization state by
a new apparatus for thermoanalysis, which was composed of thermogravimeter and
conduction-type scanning calorimeter. Mixed plastics of PE,PP,PS and PVC,
which contained PVC in the range from 4 to 40 wt%, were also analized.
Performance test for dechlorination of mixed plastics were conducted by
using an extruder which has two shafts rotating at opposite directions.
Dechlorination ratio for mixtures of two or four kinds of plastics which
contained PVC at 4 to 40 wt%were accomplished to 99.9 wt% under the conditions
of decomposition temperature at 340 ,and residence time of the plastics
above 5.0 minutes.
Measurements of thermal properties of dechlorination-treated plastics were
done.
Tests of oil recovery from treated plastics by thermo-catalytic decomposition
were conducted and gasoline-like oils were obtained.

13 The improvement of combustors is the important subject to solve the problem
of the global environmental issue. The object of this research is to
elucidate the combustion mechanisms of fuel and to establish the clean and
efficient combustion technology. The example of research subjects is the
emission control of CO2 and NOx from the standpoint of combustion mechanisms.
Microgravity environment is adopted to simplify the phenomena of combustion
for experimental observation. It is possible to eliminate the effect of
natural convection and to make a homogeneous mixture of particulate fuel and
air under the microgravity environment

13 This study aims to develop a new method for the sequestering of CO2 in deep
sea as CO2 hydrate. Under the temperature and pressure conditions of deep
sea, the mixture of CO2 and water forms the crystalline molecular complex,
called CO2 hydrate clathrate. CO2 molecules is enclosed within the lattice
formed by water molecules, which are strongly hydrogen bonded with each other.
As the density of CO2 hydrate is higher than that of sea water, CO2 hydrate
would be sequestered in deep sea. To investigate the feasibility of deep sea
CO2 sequestering, it is necessary to study the physical properties of CO2
hydrate. The object of this study are to investigate the formation and
dissociation processes of CO2 hydrate and its physical properties.

13 The objectives of this research project are to elucidate the mecha-nism of
nitrogen and nitrous oxides (N2O and NOx) formation and to develop new
combustion technology for simultaneous control of N2O and NOx emissions
from bubbling and circulating fluidized-bed coal combus- tors. The effects
of operating conditions, and coal and combustor typeson the emission levels of
N2O and NOx have been examined using experi- mental combustors. In addition,
catalytic effects of CaO, MgO and hematite particles were examined to reduce
the emission levels. Finaly a novel technique for simultaneous reduction of
the emissions, the ITS System, has been proposed based on the above
experience. The ITS Systemenables us to reduce NQO and NO emissions
respectively by over 85% and 60% in the bubbling fluidized-bed combustor.

enzymes in human liver. In the conventional mutagenic bioassay systems,
extract from rat liver has been used for an alternative of human liver
extract. This study aims to establish yeast and mammalian cell lines that
express the human metabolic enzymes by the genetic engineering and assay
