Abstract
Described herein are results of survey on brown coal liquefaction techniques and peripheral techniques, centered by COSTEAM process under development in USA, solubilization by alcohol and liquefaction and cracking with the aid of tetrahydroquinoline as the hydrogen donor under development in Japan, and low-temperature carbonization and new promising techniques. The COSTEAM process shows higher reaction rates, conversions and oil yields for brown coal liquefaction than the one using hydrogen gas. Some of the problems involved in this process high viscosity and oxygenated compound content of the product oil. The product oil is acceptable as fuel for power generating plants and can be produced at a moderate cost, but may be unsuitable as vehicle fuel. Coal liquefaction and solubilization processes are mainly represented by those which use hydrogen. The hydrogen cost, which is high, determines the product price. The processes which use alcohol or tetrahydroquinoline are still in the experimental stage. (NEDO)
