| (1)The management and the offer of the technical information on coal |
 |
| JCOAL has established "Information and Dissemination Center" staffed by a team of knowledgeable people. The Center manages all information on coal in a uniform way including data on geology, infrastructure and mines as well as on coal utilization technology and environmental technology. At the same time, the Center provides information, such as the publications of "Coal Note" and "Clean Coal Technologies in Japan", the offer of the data on coal by "JCIS" and the distribution of related information by "JCOAL Mail Magazine", and carries out various activities to facilitate resource development projects and the dissemination of clean coal technology. |
 |
|
| (2)The forming of a resources development projects |
|
| JCOAL has been conducting geological survey and the assessment of
preliminary mining plans in China, Indonesia, Vietnam, Russia and other
coal producing countries. In addition, we carry out extensive research
projects including the development of necessary infrastructure, assessment
of coal mine methane (CMM) and promotion of coal utilization technology
in these countries. |
|
| (3)The finding of the CDM projects |
|
| JCOAL hosts seminars and conducts field surveys on such technologies as
the coal bed fixation of carbon dioxides by substitution of carbon dioxides
with methane gas, the recovery and utilization of CMM and monitoring of
greenhouse gases with the aim of establishing the foundation of global
environmental technology. Moreover, we carry out surveys and research
activities concerning global warming including project finding and the
domestic emission trading system in order to bring about the Kyoto
Mechanism, which includes the Clean Development Mechanism (CDM) and
Joint Implementation (JI). |
|
| (4)The promotion of the coal utilization |
|
1) Coal Technology Workshop
JCOAL holds the Coal Energy Partnership Business Forum (the CCT
Workshop) jointly with Tsinghua University. The Forum is aimed to
conduct the matching of technology seeds with the needs of Asian countries
and build a business network of energy-related Japanese and Chinese
enterprises in CCT (clean coal technology). We also carry out a study to
develop the strategy for the introduction and wider use of CCT.
2) The strategic investigation for the introduction & dissemination of clean coal technology to P. R. China
JCOAL implements the strategic investigation and works out the conditions for the introduction and dissemination of clean coal technology to P.R.China which is one of the biggest coal consuming countries in the world. |

| (5)UBC Process |
|
UBC (Upgraded Brown Coal) Process has been developed as LRC (Low Rank Coal) upgrading technology, based on the slurry dewatering process which was a pre-treatment process in Brown Coal Liquefaction Process.
Half of the world’s coal resources are so-called LRC such as lignite (brown coal) and sub-bituminous coal. LRC still remains to be local energy sources, because it has high moisture, low heating value and high propensity of spontaneous combustion. Upgrading technology can be convert LRC into high grade solid-fuel with higher heating value and less propensity of spontaneous combustion.
The effective utilization of the large LRC resources present in Indonesia is of great importance not only Indonesia but also Japan in maintaining stable coal supply security. This LRC upgrading technology project was launched in 2001 as a joint project between Japan and Indonesia. The aims of this project are to demonstrate UBC process by operation of 3 tons/day demonstration plant and to evaluate the feasibility of the commercialization. |

| (1)Quality control for coal cleaning |
 |
We are challenging a new field of technology regarding undergroundgasification of unused coal resources and the treatment of coal washing waste, in addition to conventional coal cleaning, the recovery and use of methane gas from mines, rehabilitation of the mined coal-mine, and sequestration of carbon dioxide on the coal bed. We are also working to find CDM and JI projects and make them commercially viable.
1) Support Project to Introduce an Advanced Coal Cleaning System
We are following up on a support project to introduce and advanced cleaning system that was implemented at the Cuo Ong coal preparation plant in Vietnam痴 Ha Long bay region.
2) Joint Research into a High-efficiency Coal Cleaning System
In Indonesia, we are continuing a joint research project into a system that will efficiently clean the raw coal, which varies in its composition and nature, in order to improve the efficiency of the selection process, stabilize the quality of the manufactured coal, and thus decrease the burden on the environment.
Recently preventing the occurrence of substances such as sulfur oxide that accompanies the use of coal has become a pressing concern due to increasing demands to protect the environment.
Coal cleaning is an effective method that contributes to preserving the environment as it can, up to a point, remove coarse particles of iron pyrite, which is one of the causes of sulfur oxide, from the coal.
At the coal energy center, we have been commissioned by NEDO and are receiving assistance from METI, to carry out joint research and experimental projects to disseminate the technology in countries in the Asia-Pacific region.
