STATUS OF COAL PROJECTS (Underline denotes changes since June 1994)
COMMERCIAL AND R&D PROJECTS (Continued)
- LU NAN AMMON1A-FROM-COAL PROJECT China
National Technical Import Corporation (C-360)
The China National Technical Import Corporation awarded a contract to Bechtel for consulting services on a commercial coal
gasification project in the People's Republic of China. Bechtel will provide assistance in process design, design engineering,
detailed engineering, procurement, construction, startup, and operator training for the installation of a 375 tons per day Texaco
gasifier at the 200 metric tons per day Lu Nan Ammonia Complex in Tengxian, Shandong Province. The gasifier was completed in
1991, and has replaced an obsolete coal gasification facility with the more efficient Texaco process.

Technology Corporation and United States Department of
Since the mid-1980s, Coal Technology Corporation (CTC), formerly UCC Research Corporation, has been investigating the
pyrolysis of coal under sponsorship of DOE's Morgantown Energy Technology Center. This work initially was the development of
a batch process demonstration unit having a coal feed capacity of 120 pounds per batch. The process produced coal liquids to be
used for motor fuels and char to be potentially used for blast furnace coke and offgas.
In January 1988, DOE and CTC cost shared a $3,300,000 three-year program to develop a process demonstration unit for the
pyrolysis of 1,000 pounds/hour of coal by a continuous process. This work involved a literature search to seek the best possible
process; and then after small scale work, a proprietary process was designed and constructed. The unit began operating in
February 1991. Test runs have been made with a variety of caking bituminous coals and no major differences in coke making were
observed.
In the CTC mild gasification process, coal is heated from ambient temperature to around 400F in the first heat zone of the reac
tor, and then to 800 to 900F in the second heat zone. Lump char discharged from the reactor is cooled in a water jacketed auger
to 300F. At present, the char is stored, but in an integrated facility, the cooled char would then be crushed, mixed with binder
material and briquetted in preparation for conversion to coke in a continuous rotary hearth coker. The moisture and volatile
hydrocarbons produced in the reactor are recovered and separated in scrubber/condensers into noncondensibles gases and liquids.
The coal liquid, char, and coke (CTC/CLC) mild gasification technology to be demonstrated involves the production of three
products from bituminous caking type coals: coal liquids for further refining into transportation fuels, char for ferro-alloy produc
tion, and formed coke for foundry and blast furnace application in the steel industry. The CTC/CLC process will continuously
produce blast furnace quality coke within a 2-hour duration in a completely enclosed system. The coal liquids will be recovered at
less than 1,000F for further refining into transportation fuel blend stock.
The processing involves feeding coal into CTC's proprietary mild gasification retort reactors at operating about 1,000F to extract
the liquids from the coal and produce a devolatized char. The hot char is fed directly into a hot briquette system along with addi
tional coking coal to form "green"
briquettes. The green briquettes will directly feed into the specially designed rotary hearth con
tinuous coking process for final calcining at 2,000*r to produce blast furnace formed coke. The small amount of uncondensed
gases will be recirculated back through the system to provide a balanced heat source for the mild gasification retorts and the rotary
hearth coking process.
Research work on the pilot plant is continuing with emphasis on the production of 4"x5"x6"
briquettes for the foundry industry.
The process is now ready for commercial use. Several major companies are in negotiations with CTC for licensing and building
commercial coke plants using the CTC/CLC process. The first demonstration plant, planned to be build in West Virginia, is per
mitted to process 250.000 tons of coal per year.
- MONGOLIAN ENERGY CENTER People's
Republic of China (C-390)
One of China's largest energy and chemical materials centers is under construction in the southwestern part of Inner Mongolia.
The first-phase construction of the Jungar Coal Mine, China's potential largest open-pit coal mine with a reserve of 25.9 billion
tons, is in full swing and will have an annual capacity of 15 million tons by 1995.
The Ih Je League (Prefecture) authorities have made a comprehensive development plan including a 1.1 billion yuan complex which
will use coal to produce chemical fertilizers. A Japanese company has completed a feasibility report.
The region may be China's most important center of the coal-chemical industry and the ceramic industry in the next century.
