摘要

Predicted shortages in petroleum supply in the next 10 to 60 years and estimated coal reserves 25 times larger than the current proven oil reserves have prompted the use of coal as feedstock for liquid-fuel synthesis for the transportation and industrial sectors. Low thermal efficiencies and excess CO_2 production have prevented development of large-scale coal-to-liquid (CTL) fuel synthesis plants. Gasification of solid coal is the first and most energy intensive step in CTL fuel synthesis process. Therefore, the understanding of the thermo-chemical and kinetic processes in gasification is important to improve the overall CTL process. However, application of detailed laboratory experimentation and diagnostics of the gasification process are rare due to the severe operating conditions. Presence of fine coal particles, ash, and slag add to this difficulty.
