A method for reducing the nitrogen content of a syncrude feed obtained from at least one of oil shale, tar sands, and coal wherein the syncrude is mixed with an extractant-catalyst which is effective for extracting nitrogen materials from the syncrude feed and also effective as a hydrocracking catalyst for said syncrude feed. Said mixing helps form a first phase composed of a first low nitrogen syncrude product and a second phase composed of said extractant-catalyst and high nitrogen syncrude feed, separating said first and second phases from one another, and hydrocracking said second phase to produce a second low nitrogen syncrude product.
