Research on Solvent Extraction Process of Coal for Direct Carbon Fuel Cells

Abstract:

Two different extraction methods, microwave extraction and traditional soxhlet extraction, were used to evaluate the optimal extraction process of coal for direct carbon fuel cells through enrichment efficiency of the organic components and extraction time required under the same extraction rate. The experimental results showed that the extraction rate of microwave extraction was 9.7368% when adopted tectonic coal of 8th coal mine as sample, selected 80mL pyridine as solvent, set 95W as microwave power and 3min as extraction time. Under the same extraction rate condition, soxhlet extraction time is 35.73h, and the extraction efficiency of the microwave extraction was 714.6 times that of the soxhlet extraction. The microwave extraction was a simplify and promising working for coal, which was used as raw fuel for direct carbon fuel cells, with fast extraction speed, large sample capacity, energy saving and environmental friendly.
