Abstract
A continuous-flow extraction was conducted on kerosene fraction derived from Wyoming coal by methanolmediatedextraction
Continuous operation was performed for 100 hours with feedstock supplied at a rate of 1kg/hr, demonstrating stable operation. The extraction yields of treated oil and phenols were almost constant throughout the duration of the operation. To 100kg of feedstock supplied, 19.5kg of crude phenol including 50.8wt% of phenol, cresols and ethylphenols and 78.8kg of treated oil were obtained.
Those extraction yields were 84.4%, 75.3% and 62.5%, respectively. The extraction yields well corresponded to those from batch experiments.
