Morrell, J C

The invention relates to a continuous process to produce shale oil from oil shales. It comprises an improvement, the purpose of which is to remove relatively small and up to substantial amounts of the water present as steam; and to prevent pitch formation, and ''stickiness'' in a second or retorting stage of the process, carried out at a much higher temperature. The first step may consist of a fixed vertical vessel in one aspect of the process or alternately a much smaller rotating horizontal vessel than that used in the second step of the process. The first step is conducted at a temperature from ambient, preferably 212/sup 0/ F up to 550/sup 0/ F. The second or retorting step is conducted at 800/sup 0/ F to 1000/sup 0/ F. Indirect heating of the oil shales is employed in all cases.
