ABSTRACT:
A method for reducing the nitrogen content of a feed stream derived from oil shale and/or coal comprising hydrodenitrogenating the feed stream, subjecting the hydrodenitrogenated feed stream to first flashing conditions to remove hydrogen, hydrogen sulfide, and ammonia, dehydrogenating the remainder of the feed stream, and subjecting the dehydrogenated feed stream to second flashing conditions to separate hydrogen from the process product.
