摘要：
The effects of extraction time, temperature, flow rate, and pressure on percent extraction, the relative amounts of extract fractions, and their time distribution were studied to formulate a qualitative model for the mechanism of supercritical extraction of coal. The solvent used was toluene; the solute was a Wyodak subbituminous coal. Factorial experimental designs and the Yates algorithm were useful in model building. © 1990, American Chemical Society.
