Abstract
High boiling hydrocarbons are upgraded to products including low aromatic content kerosene or jet fuel in a dual reaction zone process. Feeds such as gas oils are fed to a hydrocracking reactor, with the effluent separated into vapor and liquid fractions. The vapor fraction is partially condensed to yield a liquid comprising kerosene/diesel boiling range hydrocarbons which is charged to a hydrogenation reactor. Liquid recovered from both reactors goes to a common fractionator. Vapor remaining after the partial condensation goes to the hydrogenation zone product separator to recover recycle hydrogen.
