摘要
A method is described for converting nitrogen containing oil stock such as shale oil syncrudes or other stocks of high nitrogen level by cracking in the presence of C.sub.2 to C.sub.5 hydrocarbons and/or methanol with an acidic zeolite cracking catalyst. Cocracking of the high nitrogen stock with the carbon-hydrogen contributors provides appreciable denitrogenation of the charge thus decreasing the need for hydroprocessing the charge with attendant savings in operating costs.
