STATUS OF COAL PROJECTS (Underline denotes changes since June 1994)
COMMERCIAL AND R&D PROJECTS (Continued)
In order to obtain a higher gasification efficiency, it is necessary to optimize the oxygen/coal ratio provided to each burner. That
is, the upper stage burners produce reactive char and the lower stage burners generate high temperature gas. High temperature
gas keeps the bottom of the gasifier at high temperature, so molten slag falls fluently.
The specifications and target of the pilot plant are as follows:
Coal feed
Pressure
Temperature
50 ton per day
30 kg/cm g
About 1,800C
Oxidant Oxygen
Coal Feed
Slag
Dry
Discharge Slag Lock Hopper
Refractory Lining
Water-cooled slag coating
Dimensions Outer Pressure Vessel 2 Meters Diameter, 133 Meters Height
Carbon Conversion 98 Percent and more (target)
Cold Gas Efficiency
78 Percent and more (target)
Continuous Operation 1.000 Hours and more (target)
The execution of this project is being carried out by the Research Association for Hydrogen from Coal Process Development, a
joint undertaking by nine private companies, and is organized by NEDO. Additional research is also being conducted by several
private companies to support research and development at the pilot plant. The nine member companies are:
Idemitsu Kosan Co., Ltd.
Osaka Gas Co., Ltd.
Electric Power Development Company
Tokyo Gas Co., Ltd.
Japan Energy Corporation
Toho Gas Co., Ltd.
The Japan Steel Works, Ltd.
Hitachi, Ltd.
Mitsui SRC Development Co., Ltd.
NEDO succeeded in maintaining 1,149 hours of continuous operation and achieved the target gasification efficiencies of the
HYCOL pilot plant in January 1994.

of Gas Technology (IGT), Kerr-McGee Coal Corporation, Illinois Coal Develop
Kerr-McGee Coal Corporation is heading a team whose goal is to develop the Institute of Gas Technology's (IGT) MILDGAS ad
vanced mild gasification concept to produce solid and liquid products from coal. The process uses a combined fluidized-
bed/entrained-bed reactor designed to handle Eastern caking and Western noncaking coals.
The 24 ton per day facility will be built at the Illinois Coal Development Park near Carterville, Illinois. The 3-year program will
provide data for scaleup production, coproducts for testing, preparation of a preliminary design for a larger demonstration unit,
and the development of commercialization plans.
Kerr-McGee Coal Corporation will provide the coal and oversee the project. Bechtel Corporation will design and construct the
process development unit, and Southern Illinois University at Carbondale will operate the facility. IGT will supply the technology
expertise and supervise the activities of the team members.
The technology will produce a solid char that can be further processed into form coke to be used in blast furnaces as a substitute
for traditional coke. Liquids produced by the process could be used to manufacture such materials as roofing and road binders,
electrode binders, and various chemicals.

M-C Power has a goal of bringing a market-responsive, natural gas fueled IMHEX molten carbonate fuel cell (MCFC) to the
power generation industry by the end of the 1990s. The technology for this MW-Class (1 MW nominal capacity) power plant for
use in distributed generation and cogeneration applications is being developed through a step-wise demonstration program which
began in 1990 and will continue through 1998. M-C Power leads a team which consists of M-C Power, the Bechtel Group. Stewart
and Stevenson Services, Inc. and the Institute of Gas Technology. This team provides both the market and power plant expertise
for this commercialization effort.
