ABSTRACT:
A method for decreasing the foaming tendency of hydrocarbons, particularly lube basestocks, is disclosed. The method comprises passing the hydrocarbon through an adsorption zone having an adsorbent, preferably a basic adsorbent therein. In a preferred embodiment, the method comprises passing the hydrocarbon feedstock through a regenerable multi-bed adsorption zone. The foaming tendency of the hydrocarbon exiting from the bed in service is monitored. The flow to each particular bed in service is discontinued and the bed regenerated when the foaming tendency of the hydrocarbon exiting from each particular bed exceeds a predetermined value.
