Abstract
A process for removing undesirable elements, e.g. nitrogen, sulfur, oxygen, from the light organic liquid product derived from a solvent refined coal liquefaction process, while preserving octane number, which comprises the steps of (1) subjecting the light liquids to an ion-exchange resin treatment and (2) contacting the resulting ion-exchanged liquids with a zeolite acting as an adsorbent under specified conditions of space velocity, temperature and pressure.
