Abstract

A nuclear magnetic resonance technique was used to determine the hydrocarbon content of a porous material during its displacement by an oil-miscible but hydrogen-free liquid (CCl4). After displacement of heptane by an amount of carbon tetrachloride equal to 1.5 times the pore volume, about 10 percent of the heptane remained, presumably in "dead-end" pores.
