ABSTRACT:
A process is disclosed for separating an organic material from a composition comprising said organic material intermixed with particulate solids, the process comprising advancing a light hydrocarbon fluid through said particulate solids at an effective rate to drive said organic material from said particulate solids. In applications wherein the product produced by said process comprises said particulate solids and undesirable residual organic material intermixed with said particulate solids, said process further comprises the steps of: advancing a higher molecular weight hydrocarbon fluid through said particulate solids at an effective rate to drive said undesirable residual organic material from said particulate solids, at least part of said higher molecular weight hydrocarbon fluid remaining intermixed with said particulate solids; and advancing a second light hydrocarbon fluid through said particulate solids at an effective rate to drive remaining higher molecular weight hydrocarbon fluid from said particulate solids.
