Abstract
Whole crude shale oil is contacted with a suitable catalyst, e.g., cobalt molybdate on alumina, and hydrogen within a temperature range of about 600.degree. F.-850.degree. F. and a pressure range of about 200 psig-5000 psig until a substantial amount of nitrogen compounds contained in the oil are converted to at least basic nitrogen compounds. Hydrogen consumption is high, about 700-3000 SCF/Bbl of fresh oil charged. The contacted oil, containing basic nitrogen compounds in the oil, formed by the hydrogen contacting, is reacted with dry HCl and resulting reaction product is removed from the oil. The reaction product can be converted into hydrogen and HCl for use in the process. As a result of the severe hydrogen contacting and the HCl treatment, a major amount of the whole crude shale oil can be converted to jet fuel.
