ABSTRACT:
Raw shale oil is selectively dewaxed to lower the pour point by contacting a shale oil charge with a low acid crystalline zeolite. The low acid catalysts can be formed by extensive ion exchange of ZSM-5 type catalysts. The shale oil is dewaxed in the absence of hydrogen at high temperature and low pressure.
